Lip selection is driven by the media type, shaft speed, pressure, temperature and contamination parameters. The media used in the majority of applications is either oil or grease. Lip designs generally include a spring when the media is oil because of its higher viscosity as compared to grease. There is also a double spring design when there is media on both sides of the oil seal. Lip designs can also include a secondary lip which purpose is to mitigate particulates from reaching the sealing lip. For additional protection of the oil seal from outside particulates, a V-Ring can be used in conjunction with the oil seal to eliminate particulates.

Oil seals offer numerous style options. With the most popular styles, each can be categorized as Good, Better and Best. The manufacturer most often uses a Good (or Better) solution which was the most economical version that would perform to specifications. When replacing that oil seal, you can use the exact style or choice a Better or Best solution if your exact style is not in stock. In the charts below, you can always move up to Better and Best styles which can be substituted. Our goal is to provide our customers with the best product fast so we will stock the Better and Best styles and price them competitively.

Which means, that a few months prior, I’ve just hit 210 KPH with broken wheel bearings in what’s essentially a 20 years old coffin on wheels. Yay.

To replace a wheel bearing properly, it has to be popped out of the hub assembly, preferably using a hydraulic press. Problems can arise with the re-installation of the new bearing, as the alignment must be accurate to avoid the bearing wearing out rapidly and causing further pain.

BR Case– The BR design is same as B with additional rubber coating on the leading edge of the case. This additional rubber coating is to ensure sealing when the oil seal is seated in the groove.

If left to wear down further, a wheel bearing could seize and lock the axle, causing all sorts of additional damage to the drivetrain. Worst-case scenario, the wheel may come off the car altogether, so it’s best to get the car looked at as soon as possible if you suspect a dodge bearing. However, considering the forces that a drivetrain has to counteract during its lifetime of usage, it is impressive how long wheel bearings can last if inserted properly and looked after - depending on the car, original bearings can generally last for comfortably over 100,000 miles.

Wheel bearings play an important role within the drivetrain of any vehicle, as they provide the first connection between the moving and static areas of the car. A bearing – in its simplest form – is a friction reduction device placed within something like a wheel to aid the efficiency of rotation. This is achieved as rolling produces much less friction force than sliding.

As long as you catch a wheel bearing issue early, though, it shouldn’t be a massively expensive or time-consuming fix, and if you’re decent with a spanner, it’s potentially something you can sort yourself. Here’s what a wheel bearing is, why it’s important, and how to tell if there’s something wrong with one.

‘T’ Lip – dual lip with spring. The lip design includes a secondary dust lip to minimize particulates from entering the sealing region. This is the most common lip design.

Material: There are several material options. Nitrile (Blank), Viton (V), Silicone (S), EPDM (E), Carboxylated Nitrile (X), HNBR (H), Polyacrylate (P), and Teflon (T).

‘K’ Lip – dual lip without a spring. This lip is designed for grease applications and include a secondary dust lip to minimize particulates from entering the sealing region.

The oil seal size is specified by three dimensions: the rotating shaft diameter, the housing bore diameter, and the width (thickness). Because of the oil seal’s purpose, the correct size is critical to performance. The inside diameter of an oil seal is sized slightly smaller than the shaft diameter in order to seal lubricants inside and prevent harmful contaminants from entering. Oil seals are offered in both metric and inch sizes to ensure the correct fit. Oil seals can be looked up by size using the Oil Seal Size Chart, which narrows down oil seals as dimensions are entered.

Like all mechanical parts on a car that rotates, rub and roll, they tend to wear out eventually. There are several signs of a knackered wheel bearing. The most common is a constant drone, hum or growl from the affected wheel, which will get more noticeable as speed increases or the car turns. You may also notice less responsive steering or speed-dependent wheel wobble. On more modern cars, which often have anti-lock brake sensors integrated into the hub assembly, you might get an ABS warning light on the dash.

Hey, i have driven a car to the limit where humming sound is so loud inside that you can’t even hear a Radio. They can last a long time before they go, even if they are shot.Also had an situation where from the moment bearing started to hum, till it disintegrated it self, it lasted about 2 km…. I guess it depends on how good brand you use and how lucky you are.

As an example, this oil seal has a part number that corresponds to a Shaft Size of 3”, a Bore Size of 4”, a Width Size of 0.625”, a Style of TB2, and is made of Viton material. Conversely, the same size oil seal in Metric has a Shaft Size of 76.20 mm, a Bore Size of 101.60 mm, and a Width Size of 15.88 mm.

Oil seals are produced by a variety of manufacturers from around the globe. Part numbers vary greatly with manufacturers, so we have created a quick cross reference guide to cross oil seal lip and case designs. Sizing and material selection can be made on our e-commerce site or provide to an Inside Salesperson when placing an order. See the chart below:

Material selection is important to the life of a radial shaft seal. The elastomer’s resistance to temperature, abrasion, chemicals, weather, sunlight, and ozone can affect a profile’s longevity and performance. The two most prevalent materials are Nitrile and Viton. See our Oil Seal Materials page for details on compounds and chemical compatibility.

There’s a decent chance that at some point, you’ve had your car back from an MOT test and found a patch of orange on the results that says something along the lines of ‘play in offside front wheel bearing.’ It sounds scary - after all, in order of everything you want to function correctly on your car, the wheels are pretty far up the list.

‘V’ Lip – single lip without spring. This lip is designed for grease applications because the high viscosity of grease does not require a spring.

A2 Case– The A2 design also has a metal outside diameter but includes an inner case which provide structural rigidity. This case design is used when the diameter of the seal is larger and rigidity is required to maintain structural integrity during installation.

In addition to the Material, Lip, and Case selections, you can select to have a Stainless Steel Case and a Stainless Steel Spring. In those cases, you will find an additional indicator in the part number.

Last year I was driving from Townsville to Brisbane. And about 800km in the wheel bearing on the rear right wheel went which shook the wheel completely off. I was only a learner at the time so it was the scariest thing that had happened to me while driving. The worst part was the car had just been serviced for the trip and the bearings had been replaced.

Choosing the correct oil seal for your application is important. It is just as important that oil seals are installed properly, in which our step-by-step guide can be viewed here. Doing so ensures your desired oil seal fits and performs as intended. Oil leaks can happen even after replacing an oil seal if the shaft has wear groove damage, in which case restoration is possible with the installation of a shaft repair sleeve.

They never seize immediately. No need to fear. I have a comparison to make. My Skoda had 5 out of 4 changed in its 175 000 km lifetime. Only one bearing failure might have been caused by an accident. My E46 has had the originals for 245 000 km and 13 years. And none of them seems to be on their way out.

The most common mechanical failure is due to a seal leak, which allows the lubricating grease to exit the bearing, and water and grit managing to worm its way in. This all amounts to the degradation of the balls and the outer and inner housing of the bearing, often creating that gritty, skimming sound as the wheel is rotating. Looking inside a worn-out bearing, there will often be small specs of metal that have broken off from inside the bearing itself and are grinding their way around the racers, causing more damage. If you have had a minor shunt, it’s always worth having the hub assembly checked over afterwards.

The most common and cost effective case materials are stamped from cold rolled carbon steel. The steel is then phosphate coated to aid in the molding process and to help eliminate corrosion during storage. A simply ‘L’ shaped geometry is the most cost effective case design but a number of case geometries are available to improve rigidity, positioning and removability. oil seal cases can also include rubber molded options which address such factors as corrosion, vibration and sealing characteristics.

Although it can be a labour-intensive job if one were to fail, the shift to selling entire hub assemblies should make a bad wheel bearing fixable from home, with a decent tool kit and a bit of know-how. So do not fret the next time that horrid whir begins to creep into the cabin, as a fix may be only a ratchet spanner away.

A car’s wheel bearing does this by using small metal balls or cylindrical rollers that roll between two smooth rings of metal. Helped along by grease, the bearing rotates in tandem with the wheel’s rotation, the rolling motion of the balls or rollers allowing the wheel hub to rotate as freely as possible. It also helps absorb some of the forces exerted on the car’s wheel during acceleration, braking and cornering.

Most online parts stores will now sell the entire hub assembly with the wheel bearing pressed into it, saving the hassle and potential scope for mistakes within the specific bearing assembly. It goes without saying, but you should also make sure that, if possible, you or the garage is using an original manufacturer part or one of reasonably similar quality - this is one area you really don’t want to skimp on.

C Case– The outside of this case is rubber coated. This design is often used when a seal will be removed frequently or if sealing of bore and oil seal is of concern.

The wheel bearing is housed within the hub assembly, providing the static connection with the hub carrier through an outer ring or ‘racer’. On driven wheels, the driveshaft travels from the transmission and passes through the centre of the wheel bearing through the inner ring, creating the rotational partnership. Ball-type bearings are generally used on the driven wheels of a vehicle, while tapered roller bearings, with cylindrical rollers arranged around an inner ring, are predominantly used on the non-driven wheels.

Wheel bearings should last tens of thousands of miles, but many mechanics will simply hammer the bearing back into the hub assembly instead of precisely aligning it and using the aforementioned press. This will inevitably lead to the bearing not rotating in the perpendicular fashion that it was designed for, accelerating wear and damage to the part. It’s important, therefore, if you’re not 100 per cent confident in your own ability, to ensure you’re using a trusted, professional garage.

Global O-Ring and Seal’s oil seal part numbers are designed to describe the seal size, style, and material composition.

The durometer of an oil seal is typically dependent on the material it is made with. Common oil seal materials along with their durometers are as follows:

Wheel bearings are generally made from hardened steel, so they can withstand a serious amount of rotational abuse. But apply heat (through lack of lubrication) or dirt and water (broken seal) and all hell can break loose (this is yet another reason to avoid driving through deep water). Hitting one too many potholes or taking speed bumps too quickly can also exert excessive force on your bearings, shortening their useful life.

Oil seals, often called a rotary shaft seal or grease seal, closes the gap between stationary and moving components in mechanical equipment — most often rotating shafts — helping prevent lubricant escape and stopping harmful materials, such as dirt, from moving in through the clearance. Oil seals are most commonly used in gearboxes, hydraulic cylinders, and related components.
