The choice of a fit is highly dependent on the operating conditions. The right choice is determined by the rotation ratio. A rotation ratio is about the movement of the bearing ring, which is the inner or outer ring, in relation to the direction of the load.

Chances are when you start hearing a loud noise from under the hood of your car as you’re driving, you automatically think it’s an exhaust leak or your car is going to break at any moment. But have you thought about the possibility of a broken — or nearly broken — wheel bearing causing that noise?

The clearance of the bearing determines to a large extent the life of and the noise in the bearing. The clearance is indicated in:

The coherence of the entire ISO fitting system in relation to choices, schedules and recommendations for loose, fixed and sliding fits is further elaborated in the catalogs of our manufacturers.

The internal clearance of a bearing, measured without load, is the distance that one ring can move relative to the other ring. There is usually a difference between the radial play of an unmounted and a mounted bearing. This difference is due to the chosen shaft and housing fit tolerances, which can stretch the inner ring and/or compress the outer ring. The initial play before mounting is always greater than the play during operation. When bearings are in service, there are also changes in clearance due to thermal expansion between the inner and outer ring.

Tire Wear and Tear. What about your tires? We all know the importance of rotating your tires to promote even wear, but did you know a broken wheel bearing can lead to uneven tire wear too? The looseness of the wheel and the vibration that reverberates through the wheel cause your tires to wear unevenly, meaning you are more likely to have to invest in new tires sooner.

A: Common causes include poor maintenance, water and dirt contamination, extreme driving conditions, and manufacturing defects.

Car Feels Loose. Does your car feel loose? When you hear professional drivers talk about a “loose” car, you may not know what that means. It often refers to the steering of the vehicle, which can include wheel bearings. Wheel looseness, or also called wheel play, is another common symptom of a bad wheel bearing. As the bearing begins to wear down, they become loose inside the wheel hub and spindle, which makes your vehicle feel loose while steering.

When wheel bearings wear out, they can have a significant impact on vehicle performance, leading to increased friction and resistance within the wheel assembly. This extra friction forces the engine to work harder to maintain the same speed, resulting in decreased fuel efficiency. Additionally, worn bearings can cause uneven tire wear, as the compromised alignment and stability of the wheels lead to irregular contact with the road surface. Hitting a pothole or other road hazard can exacerbate bearing damage, potentially causing sudden bearing failure and loss of vehicle control. The deterioration of wheel bearings also affects the proper transfer of torque from the engine to the wheels, further compromising handling and increasing braking distance.

A: While possible, replacing a wheel bearing requires specific tools and expertise. It’s recommended to seek professional help for accurate installation.

A rotating load exists when the ring is stationary and the load rotates or when the ring rotates and the load is stationary. A stationary load is the situation where both ring and load are stationary or both are rotating at the same speed. Another possibility is an indefinite load if the direction of the load varies due to impact or vibration.

Vehicle Pulling to One Side While Driving. Are you doing the steering, or is the car driving where it wants to? When a wheel bearing corrodes or becomes pitted, the smooth exterior lining is gone and the vibration is transmitted to the tires which may feel like it is “pulling” to one side or the other. As the bearing on one side deteriorates, it puts more pressure on the opposite bearing, leading to uneven wear and increased friction. This uneven wear generates heat, which further accelerates the degradation of the bearing. As a result, the affected wheel may start to wobble or vibrate, robbing the vehicle of its stability and smooth handling, especially when cornering or driving at higher speeds.

Unusual Noises Coming From the Wheels. Listen carefully. The most common and often most-identifiable symptom associated with a bad wheel bearing is noise coming from the wheel or tire area of the moving vehicle. You may mistake this as engine noise, but when you listen closely you will likely hear grinding or grating that gets louder as the vehicle accelerates. Since wheel bearings are not known for wearing out too frequently, the noise is typically suspected to be something else and the problem gets overlooked.

A: Typically, wheel bearings last between 85,000 to 100,000 miles, but this can vary based on driving conditions and maintenance.

To achieve the optimum service life of a bearing, the selection of the right bearing is of course a prerequisite. If the shaft and housing fit are not properly matched to the bearing, even the correct bearing will fail prematurely.

C0: Standard clearance for applications where the normally recommended fits and under normal operating conditions leave a more or less correct clearance

The ISO tolerances for the shaft and housing together with the tolerances for the bore and outer diameter of a bearing give the fit. The ISO tolerances are defined in a form of tolerance fields relative to the zero line. The position of the tolerance field is indicated by a letter. Capital letters are used for the houses and small letters for the axes.

A: Driving with a bad wheel bearing is dangerous as it can lead to wheel failure and accidents. It should be addressed immediately.

In general, bearings should have practically no play in service condition. This applies in particular to ball and spherical roller bearings, tapered roller bearings and cylindrical roller bearings. This is a small positive clearance of a few microns. The selection of the correct clearance depends on, among other things, the application, the shaft and housing fits, and the temperature in the bearing and the machine.

Wheel bearings are essential in the operation of your vehicle. More precisely, a wheel bearing is crucial for the proper function of the hub, tire, and wheel assemblies to work together. The wheel bearing allows friction-free movement and rotation of the hub assembly, and thereby provides smooth tire and wheel rotation. Worn-out or damaged wheel bearings can lead to a range of problems that affect vehicle performance and safety, making it essential for drivers to recognize the signs of trouble.

The radial clearance classes for unmounted bearings are defined in ISO standards and tables. With the most common bearings, such as deep groove ball bearings, spherical roller bearings and cylindrical roller bearings, the play is determined during production.

The material of the shaft or housing is also a factor to consider. For example, aluminum expands more than steel when heated. There are also more factors that play a role. Think of a thin-walled housing, a hollow shaft or high vibrations.
