Thermal Range Calculator: Calculates the thermal expansion effects due to operating temperatures to find the right shaft and housing tolerances for the application.

The first caged bearings for axles were patented in the late 1700s, and the design that has carried forward to modern times is basically a set of steel balls or rollers that are housed within a ring-shaped housing called a race. Most ball bearings will have an inner race, which is grooved and holds the balls on the inside, and a grooved outer race on the outer circumference of the bearing. In a roller bearing, the race has slots that allow the rollers to spin against the axle on the inside and the wheel on the outside.

Using our thermal range calculator, you can manipulate the shaft and housing tolerances to automatically find the best tolerance for the resultant fit.

We recommend using a slip fit on the housing so bearings can move axially for spring preloads or to absorb thermal expansion.

Back in the days of horses and carriages, wheels were attached to the carriage by way of a wooden or metal stick axle that was fixed to the carriage, requiring the wheels to rotate on the axle. A major drawback of this setup was that there was a lot of friction between the wheel and the axle, and that friction made it harder to move the carriage, resulting in wasted energy. The other issue was that the friction would cause a lot of wear and tear on the axle and wheel where they joined, so you’d need to do constant maintenance on the joint.

Machined parts and components all have tolerance standards when manufactured. These standards produce a consistent, uniform product.

On applications where the shaft is rotating, using a press fit will prevent the bearing’s inner ring from rotating, relative to the shaft. If the inner ring rotates separately from the shaft, then micro-fretting and premature bearing failure could occur.

Wheel bearings have come a long way since the days when you had to repack them every several thousand miles, but they still do fail on occasion. Keep reading to learn how to identify a bad wheel bearing by the sounds it makes and what to do to avoid a wheel bearing to go bad.

Be sure to consult your owner’s manual, a repair guide, an AutoZoner at a store near you, or a licensed, professional mechanic for vehicle-specific repair information. Refer to the service manual for specific diagnostic, repair and tool information for your particular vehicle. Always chock your wheels prior to lifting a vehicle. Always disconnect the negative battery cable before servicing an electrical application on the vehicle to protect its electrical circuits in the event that a wire is accidentally pierced or grounded. Use caution when working with automotive batteries. Sulfuric acid is caustic and can burn clothing and skin or cause blindness. Always wear gloves and safety glasses and other personal protection equipment, and work in a well-ventilated area. Should electrolyte get on your body or clothing, neutralize it immediately with a solution of baking soda and water. Do not wear ties or loose clothing when working on your vehicle.

It’s important to know about tolerances because, during operation, temperatures rise causing the bearings, shaft and housing to expand, along with their respective tolerances. Be prepared for these changes when machining a shaft and housing unit so that you are choosing the correct bearing and fit for your application.

The best protection for your bearing. Easy to install with a simple “drop-in” next to your bearing. No added space needed. CF seals offer 100% sealing efficiency against splashing liquids.

Designed with grooves in the outer ring to offer more protection (than our L-type seal) against contamination and direct spray liquids. Liquid gets pushed out through outer grooves when in rotation.

There are a few things to listen and feel for when attempting to diagnose a bad wheel bearing. Some of the sounds that we associate with bad bearings can also be indicators of problems with other parts of the vehicle, but there are a few tricks to test whether the noise is a bearing issue. Here are a few sounds that can indicate a bad bearing:

Finding the right shaft OD to match the inner ring (or ID) of the bearing and the correct housing ID to match the outer ring (or OD) of the bearing, produces a resultant fit.

Frontwheel bearingnoise symptoms

Once you’ve done the road test and have an idea of where the sound is coming from, park your car, jack it up, and remove the tire. Don’t forget to use jack stands! With the tire off, rotate the bearing to see if there is undue resistance or if you can feel or hear clicks, grinding or other sounds coming from the bearing. It should be smooth and quiet. You can also try to wiggle it back and forth and there shouldn’t be any play in the bearing.

We know that not every application requires super, high-precision bearings. We stock other industrial parts from quality brands.

Badwheel bearing problems

Bearings have tolerance standards for the inner diameter (ID) and the outer diameter (OD). Machined shaft and housings also have tolerance standards on their parts that range around 10µm.

Other tolerance recommendations such as shaft and housing concentricity, surface roughness and runout and are located on pages 70-72 of the GMN Bearing catalog.

Some of these symptoms can also be a result of bad tires, or even a bad CV joint, but a bad bearing will sound worse when it is put under load, like when the car is turning, so use this method to test and see if it is your bearing that’s causing the noise:

When it’s time to shop for a new wheel bearing, AutoZone has all the parts and tools you need to keep your car rolling, and we have locations in every state that you can find by using our Store Locator.

In rotating shaft applications, we recommend a press-fit between the shaft and the inner ring (ID) of the bearing and a slip-fit between the housing and the outer ring (OD) of the bearing, when in use.

In automotive applications, the wheel bearings are usually sealed units that connect the wheel to the suspension of the vehicle. Your wheel studs will typically be part of the bearing and if it is a drive wheel, there can be a hollow in the middle of the bearing where a spindle is inserted from the axle shaft.

You may find that the car wanders on the road, your tires may wear unevenly, the friction heat from the failed bearing could damage other parts of the car, and the wheel could actually separate from your car.

Since the wheel bearing is the sole point of contact between the car and the wheel, it’s very important that it is functioning properly. A bad bearing will be noisy, could lead to heat damage of other components, and could seize up or cause the wheel to break off the car, leaving the driver stranded.

Our ABEC 7, P4+ precision class of bearings allow for tighter resultant fits for those doing final grinding / lapping just before assembly. We provide the exact bearing inner diameter (ID), outer diameter (OD) and width (W) value deviation from nominal for each specific bearing which will also give you a tighter resultant fit.

20161024 — Wheel bearings are known to cause humming. However they are usually noticeable at all speeds and get louder as speed increases.

For high-speed applications, the centrifugal force could cause the inner ring to expand and lift off the shaft which could lead to drastic machine malfunctions and a decrease in bearing life. Increasing the press-fit on the bearing and shaft would help counteract this scenario.

Your wheel bearings impact efficiency and keep the wheels attached to your car, so it’s important to use the best possible parts to complete any repair. Replacing your own wheel bearings can be an afternoon or evening job, depending on the make and model of your vehicle, so do a bit of research and don’t be afraid to tackle this important repair yourself.
