WHY ARE WHEEL HUB ASSEMBLIES IMPORTANT?

Wheel hub assemblies connect your vehicle’s wheels and rotor to the caliper and allow smooth rotation. They are typically attached to the steering knuckle or rear axle flange/spindle, and depending on the application, they may feature ball or tapered rolling elements.

Designed to minimize friction and support the wheel load , wheel hub assemblies reduce the resistance of your wheels when in contact with the road. They also control wheel positioning, which determines several performance factors, including tire wear, braking control, vehicle stability in both straight lines and turns, and overall vehicle handling.

Wheel hub assemblies may be considered an important part of a vehicle’s ABS, TCS and ESC systems. Based on continuous inputs from the integrated ABS sensor, these control systems ensure safe operation.

Requirements for wheel hub assemblies include:

Precision machining of raceway and flanges

Premium rolling elements (optimized size, finish and material)

High-quality lubricating grease

Durable seal construction and material

Accurate ABS sensor signal and plug

Exact orbital roll forming

Designed as pre-assembled units, wheel hub assemblies feature precision machined rolling elements, seals, mounting flanges and commonly, integrated ABS sensors. They are pre-adjusted and pre-set, so they require no maintenance.

Automotive Applications Use Two Types of Rolling Elements

Ball Bearings/Sphere Shaped Rolling Elements

Double row angular contact wheel bearings work best in light- to medium-duty applications. They have a good capacity to handle radial and axial load, and their compact design saves on weight.

Tapered/Cone Shaped Rolling Elements:

Used for larger vehicles and heavy-duty applications,tapered rolling elements have an excellent capacity to handle radial and axial load. They feature a cup and cone design.

Cup and Cone Design:

This design is used in pairs on front or rear non-driven wheels. Setting the preload is mandatory, and because they don’ t have an integrated seal, maintenance is required. Repack with grease periodically.
