Types of bearings

Checking wheel bearings for wear is easy and only requires the vehicle or wheel to be suspended. Follow these steps to check the wheel bearing on your car:

Bearingtypes

Thrust ball bearing is composed of washer-shaped raceway ring and ball and cage components. The raceway ring fitted with shaft is called shaft washer, and the raceway ring fitted with cage is called housing washer.

It can automatically adjust the shaft or housing deflection or misalignment caused by axis errors, because the outer ring raceway is spherical and has aligning capability.

It can bear radial load and axial load. A single bearing can replace the front combination or rear combination angular contact ball bearing.

Tapered roller bearing can bear large axial load and also can bear large radial load. It is designed to make the inner raceway, outer raceway and the apex of the conical surface of the roller rolling face intersect at a point at the bearing center line.

Worn wheel bearings shouldn't be ignored. The cost of a wheel bearing replacement in front or at the back is a small price to pay for reducing the safety hazards that come with this component wearing out.

Deep groove ball bearing is the most common and typical roller bearing, it has very wide applications. It can bear radial load and axial load, and is suitable for applications which require high speed rotation, low noise and low vibration.

Thrust bearing

It is composed of washer-shaped raceway ring (shaft washer, seat washer) and cylindrical roller and cage components. Cylindrical roller is crowning processed, so the pressure distribution between the roller and the raceway surface is even. It can bear single direction axial load, and with large axial load capacity. Its axial rigidity is also strong.

These are by far the easiest bearings to work with, as long as you do not live in the rust belt. Issues that arise from bolt-in bearings are bi-metal corrosion and cost. If your vehicle is equipped with an aluminum steering knuckle, expect a fight when removing the steel bearing. This mostly applies to states that suffer from increased levels of vehicle corrosion and rust due to the climate. Since replacement parts come as an assembly, the cost can be higher when compared to a press-in or tapered roller bearing. Vehicles such as the Jeep Wrangler will use these bearings on the front axle and vehicles such as the Toyota RAV4 will use these in the rear.

Deep groove ball bearings from GMN can be used universally, and reliably take axial and radial forces in both directions.

We highly recommend you avoid driving with a worn wheel bearing. Wheel bearings can become so worn that the hub can fall out of the bearing, causing the wheel to detach from the vehicle. This is a serious scenario that you’ll want to avoid at all costs. Additionally, a worn wheel bearing will reduce the vehicle’s handling and braking abilities. If your wheel bearing is only making noise and does not exhibit any wheel play when inspected, you may have some time before you absolutely need to replace the bearing. However, if the wheel has excessive play due to a worn bearing, you’ll want to get it fixed immediately.

Types of bearingsand their applications

The cylindrical roller and the raceway are in line contact, it can bear large radial load. It is suitable for heavy load and shock load and also suitable for high-speed rotation N type and NU type axially move.

Wheel bearings provide a mounting point for the wheels and allow the wheels to spin. Wheel bearings are either a tapered rolling bearing design or a ball bearing design. Ball bearing designs are either press-in or bolt-in. Let's take a look at each bearing design in more detail.

Timken® miniature ball bearings come in a variety of types and designs. They are ideal for motors, flow meters, medical handpieces and more.

There are spherical rollers between the spherical raceway outer ring and double raceway inner ring. They can be categorized into R, RH, RHA and SR 4 types according to the different internal structure.

Ball bearing wheel bearings are cheaper to manufacture and maintain than their tapered bearing counterparts. Press-in bearings require the use of a hydraulic press to safely remove and replace them. On most vehicles, such as a Honda Civic or Toyota Camry, specifically for front wheel bearing replacements, the steering knuckle will need to be removed. Removing the knuckle will require wheel alignment afterward. Due to the need for a hydraulic press, the need for wheel alignment, and the depth of the repair, most people opt to let the pros handle it. There are options such as removing the steering knuckle at home and taking the assembly into a shop and having them press the old bearing out and the new bearing in. When it comes to press-in bearings, a replacement wheel hub will be the most expensive part. Aftermarket parts such as NAPA offer full assemblies for replacement. This may be the better option, depending on how rusty or worn your vehicle is.

How much is it to fix or replace a wheel bearing? That depends on the make/model of your car as well as the type of bearing. RepairPal estimates a wheel bearing replacement will cost you between $300 and $400. This estimate can be accurate for most vehicles. However, if we look at the pricing for the popular Toyota Tacoma, the price jumps as high as $740. Using a whole knuckle assembly from NAPA or other parts suppliers will cost between $250 and $500, plus labor. Like most repairs, if you do them yourself, you can save some money. However, when it comes to serviceable bearings and press-in bearings, we recommend you let the pros handle the repair, especially if you live in the rust belt.

Tapered roller bearings are serviceable, which means they can be removed, cleaned, and repacked with grease to prolong their life. Aside from lasting longer, serviceable bearings are cheaper to replace. However, over a lifetime of service, it may add up to maintenance services/costs. Unfortunately, the majority of vehicle manufacturers do not offer serviceable bearings anymore. Years ago, the Ford F-150 and Toyota Land Cruiser used this style of bearing. The biggest drawback of tapered roller bearings is improper maintenance. Overloaded or improperly pre-loaded bearings wear prematurely. Improper grease packing is another issue when it comes to maintenance.

If you notice growling or clunking noises, vibrations, abnormal tire wear, or excessive steering wheel play, your car may have one or more worn wheel bearings. Wheel bearings are what make our wheels go round, literally. Despite their simple design and purpose, wheel bearing replacements can be costly. The type of wheel bearing used is entirely dependent on the manufacturer, and you may pay more for a repair on a luxury vehicle. When it comes to replacing bearings, you can do this repair yourself on certain vehicles, while for others, you may need to recruit the help of the pros. In this article, we are going to cover what a wheel bearing is, how it works, the different design types, symptoms of a worn wheel bearing, how to check your car for a worn bearing, and how much it costs to replace a wheel bearing.

If the wheel bearing is worn, you will feel a popping as you move the wheel. Additional methods for inspecting wheel bearings include using chassis ears, a stethoscope, and a dial indicator (to measure the exact amount of wear).

There is contact angle between the cage ring and steel balls, the standard contact angle is mainly 15 °, 30 ° and 40 °. The larger contact angle the greater axial load capacity; the smaller contact angle the higher speed rotation capacity.

Bearing plays an important role in the mechanical operation. It can reduce the friction coefficient of the load and keep the center of the shaft fixed and not deviated. With bearing installed, the mechanical rotating body is well supported, so that it can run better. The bearings can be divided into two types according to the different friction properties during the movement process, one is rolling bearings, and the other is sliding bearings. Rolling bearings and sliding bearings are big categories. There are dozens of types of bearings in small category. Here in the following contents, we present you the 13 types of bearings and their main applications.
