Furthermore, they must be corrosion-resistant and withstand wear and aging to guarantee a long lifespan with optimal sealing performance.

Radial shaft seals are positioned between moving and stationary parts, or between two parts that move relative to each other. These seals comprise two main components:

V-rings are conical seals designed to adapt to various shaft diameters. O-rings are circular seals placed in a groove on the housing or the shaft, offering effective leakage protection.

Various materials, including NBR, FKM, PTFE, and metal, are available for radial shaft seals, with the choice depending on the specific requirements of the application. It's crucial to consider the size and dimensions of the sealing space and the operational conditions, such as temperature and pressure, when selecting the appropriate radial shaft seal. Moreover, purchasing radial shaft seals from reputable manufacturers is recommended to guarantee quality, maximal sealing effectiveness, and reliability.

Scope of work as per the first shop was to “replace the left/front wheel bearing and press the new one”, that’s all they mentioned.

There are various types of radial shaft seals, including standard radial seals, shaft seals, V-rings, and O-rings. Standard radial seals are the most commonly used and are available in different designs and materials. Shaft seals, also known as Simmerring seals, are employed to prevent the ingress of dirt and moisture into the ends of rotating shafts.

Same with a guy I know in my area who passed away back in 2011. He BSed, cobbled together, hacked up, and in general screwed everyone over yet everyone within 25 miles of him praised his name to the mechanical heavens. Go figure…

Radial shaft seals are utilized to prevent the escape of liquids or gases from the lateral movement of a rotating shaft. These seals are composed of an elastic material that wraps around the rotating shaft, equipped with a spring to apply uniform pressure on the sealing lip. This lip closely conforms to the shaft's surface, effectively preventing the leakage of fluids or gases into the surrounding area. Used in rotating machinery such as engines, gearboxes, and pumps, radial shaft seals serve a crucial role in avoiding leaks and prolonging the equipment's lifespan. Often, they act as a vital connection between a stationary metal housing and a rotating shaft or axle

I took my knuckle to a shop and they pressed out my bearing and he said hub was scored but he had 1 used. For $20. I tried to pay with my card and tech said hub was his and cash only. Had to run to atm for $20 cash. Bet tech had a few hubs in his toolbox. From other jobs?

Radial shaft seals must meet several requirements to ensure effective sealing. They need to be chemically resistant to the media they are sealing, provide adequate abrasion protection, and possess high thermal stability.

You did the right thing by getting other quotes and as an aside, never give a lot of credence to online reviews. Some may be fake and in some cases people may have been robbed blind and simply do not realize it. Their car is fixed for double what anyone else charges so they’re happy with it all.

Regular inspection and maintenance of radial shaft seals are indispensable for ensuring optimal performance and longevity.

After installation, the seal's fit must be verified for correctness. A correctly installed radial shaft seal ensures a durable seal, effectively preventing the escape of fluids and lubricants from the system.

Some radial shaft seals also come with a metal or plastic casing, which protects the sealing lip and makes installation easier. Additionally, certain models include an extra protective lip to block the ingress of dirt, gases, and moisture into the system.

This doesn’t include the cost of replacing one perfectly good ABS sensor that had to be destroyed in the process. (tech told me that the sensor would be in the way of the press, and they couldn’t remove it without destroying it. ). I believed him, as I replaced the ABS sensor on the other side a year earlier. It was defective. I too had to destroy the old one to remove it, as Toyota machined the hole too small. Talk about a tight fit! There was TSB about this, I believe.

Not necessarily. I had this setup on my old Mazda Protege. You press the hub out of the bearing, and the inner race of the bearing is stuck in the hub. You then carefully score the outside of the inner race, and strike it once or twice with a chisel…the inner race splits in too, and you’re left with the hub, which you can press into the new bearing.

Radial shaft seals can be made from a variety of materials suitable for their applications. Here are some common materials for radial shaft seals:

The developer of the modern shaft seal is the Austrian engineer Walter Simmer, who, on behalf of Freudenberg, developed the first shaft seal in its current form in 1929. For this reason, shaft seals or shat seal rings are often referred to as Simmerring seal even today.

They need to be tight due to the super tight tolerance on positioning for proper operation. I did some work recently and had to R&R an ABS sensor. Long story short, a thousandth made a huge difference in signal level. Too close and it rubs, too far and weak signal. Rust forming on the spacer was enough to cause weak signal…removing them required diligent care not to damage them…

Yeah, tight but not pressed in I had to pry mine out a fraction at a time, going around to keep it from getting jammed. Both GM and an 03 Toyota Camry. The GM had a penta-socket head fastener on one side and a pressed in “rivet” on the other. Still struggling to understand/justify the need for such hardware…

You didn’t mention the year of your Elantra, but when I plugged in a 2015 into repairpal.com for an estimate, my local zip code brought up an estimate for $173-266 to change a single wheel bearing…you definitely need to get a 2nd and 3rd quote

In addition to the temperature range, the desired outer diameter as well as the inner diameter and the circumferential speed must also be taken into account.It is also advisable to purchase a sufficient number of seals to allow replacement if necessary. Finally, it is important to carry out regular inspection and maintenance to ensure optimum performance and a long service life of the radial shaft seals.

Radial shaft seals are shaft seals used to prevent the escape of liquids or gases from the lateral movement of a rotating shaft. These seals are made of an elastic material, such as nitrile (NBR), fluororubber (FKM/FPM/Viton), or PTFE, and are equipped with a spring to exert a uniform force on the sealing lip.

You should also verify how many wheel bearings they’re replacing. If it were me, I would go ahead and replace the bearing on the other side of the vehicle as well…chances are, it’s not far behind in terms of failure.

The choice of the right sealing material depends on various factors, such as the requirements for the seal (e.g. chemical resistance, temperature resistance), the operating conditions (e.g. speed, pressure) and the media used (e.g. lubricants, liquids).

Generally, radial shaft seals differentiate or seal between two types of media. These are most frequently liquid and gaseous media, as well as potential environments with varying pressures.

When buying radial shaft seals, there are a few important factors to consider. First of all, the requirements of the scope of application should be precisely defined in order to select the appropriate type of seal and the suitable material. It is important to know exactly the size and dimensions of the seal space to ensure that the selected radial shaft seal fits. The operating conditions, such as temperature and pressure, must also be taken into account. It is advisable to buy radial shaft seals from reputable manufacturers who can guarantee quality and reliability.

A cylindrical outer casing with a tight fit, sealing against the bore of the housing, and a sealing lip that dynamically and statically seals against the shaft.

Radial shaft seals are made from an elastic material, such as Nitrile (NBR), Fluorocarbon rubber (FKM/FPM/Viton), or PTFE. Typically designed as a ring, they feature a sealing lip that snugly wraps around the rotating shaft, and a spring or tension spring that presses the sealing lip against the shaft. Depending on the requirements and application, the sealing lip may be executed as either a radial or axial type (Axial shaft seal).

A radial shaft seal is a sealing component used in rotating machinery and equipment to prevent the penetration of dirt and moisture into the system and to keep the escaped liquid in the system. The seal is cylindrical and is inserted into a recess on the housing or on the component, where it ensures a permanent seal between the rotating shaft and the stationary part of the system.

The installation of a radial shaft seal necessitates meticulous preparation and alignment of the shaft, along with the precise positioning of the seal element within the housing. Special tools should be used to apply the seal gently and uniformly to the shaft. To prevent damage to the seal element, care must be taken not to exert pressure on the lip area with the tool.

I thought sometimes they just replace the whole hub part is a little more but less labor. That price sounds high you need to get a second quote.

Additionally, the design of the radial shaft seal should be straightforward to install, to reduce labor costs and assembly time.

Radial shaft seals are predominantly utilized in rotating machinery such as motors, gearboxes, and pumps to prolong their lifespan and prevent leaks. They serve to seal rotating shafts across varying speeds and temperature ranges.

Cool. With that said, you really should consider getting the other one replaced at the same time…see if the shop will give you a break on the labor.

Did you get an itemized estimate? If not, ask for one. Do that when you get a second opinion too. That way you can easily compare the two. Don’t tell the second shop what the other one estimated.

Dropped my car off at a mechanic to check into an issue I’ve been having (groaning in the front/left wheel). Turns out it is a wheel bearing that needs to be replaced and the mechanic quoted me $750 for the job, saying “the bearing needs to be pressed and it’s a fair amount of labor”.

Thanks all, appreciate the help. I did call a second and third shop and was quoted $350 by one and $380 from the other. Both shops gave me their estimate, and when they then asked what I was quoted when it was diagnosed they said the shop I went to was notorious for extremely high prices and that $750 was way too high… I’m surprised since the first shop had great reviews.

Radial shaft seals are essential sealing components used in rotating machinery and systems to prevent the ingress of dirt, moisture, and other contaminants, as well as to retain any media that have leaked within the system. Their purpose is to offer an effective and durable barrier against leaks, thereby extending the lifespan of the machinery.

Radial shaft seals are available in standard, special, and custom designs, as well as in unique materials at Kofler - Dichtungen. Feel free to request a personal consultation!

Regular maintenance is important to ensure the performance and service life of radial shaft seals. It is important to check the sealing ring for wear and tears and make sure it is properly seated on the shaft. Contamination and impurities must also be removed. If the sealing ring is worn or cracked, it must be replaced. It is advisable to also check other components of the system such as bearings and sealing surfaces during maintenance to ensure optimal performance.

It should also be mentioned that radial shaft seals are often made of combined materials, since the demands on the connection to the fixed housing or the housing bore are different from those to the rotating shaft, where, for example, a PTFE sealing lip makes sense, while other parts of the seal have an elastomer outer jacket. A stiffening ring as well as a worm spring or seals with an additional dust lip can also be used to ensure ideal sealing and maximum service life.

Shaft seals are an essential element of sealing technology. Shaft seals are often referred to as Simmer rings, particularly in the automotive industry.

Elantra has same bearing setup as Honda’s. A shop can lowball the cost and then have to replace more parts or remove knuckle to press out bearing. The bearing is pressed into the hub. So, assume the hub will be damaged or scored.image600×600 22.3 KB

you can get the whole hub and bearing for like $150 , so your mechanic is telling you it is going to take him 5 hours to do the job on a bearing ?? I doubt it , i would run from that guy .

I paid $250 parts and labor for the front wheel bearing of my previous Toyota Corolla. It had to be pressed in also. They put in a Timken bearing and it didn’t take much time…around 45 minutes and I was out of there.Shop around because your estimate seems on the high side.

The sealing lip also needs to be flexible enough to closely adhere to the surface of the rotating shaft while maintaining enough rigidity to prevent tearing or dislodging.

As always when in doubt you get a second opinion . It could be that this shop does not have the right equipment for the job or there is a lot of labor involved .

After I drilled out the defective sensor , I took a reamer to the hole. The shop that removed the other sensor (left front) was nice enough to let me go home without a sensor (I got one from an online Toyota dealer at a big discount). And my labor is free.

In order to select the correct radial shaft seal, the dimensions of the seal space as well as the operating conditions such as temperature and pressure must be taken into account. The choice of material depends on the specific requirements of the application. Regular inspection and maintenance of the radial shaft seals is essential to ensure optimum performance and long service life. It is recommended to buy radial shaft seals from reputable manufacturers to ensure quality and reliability.
