FAQs

Q1: Why are double-row angular contact bearings commonly used in hub units?

A: They can handle both radial and axial loads simultaneously, which suits the combined steering, braking, and cornering forces a hub experiences. The angular contact design also allows controlled preload.

Q2: Why do some hub units use tapered roller bearings instead?

A: Tapered rollers are effective for high axial load applications, such as heavy-duty or commercial vehicles. They require careful preload adjustment, which is why they are less common in sealed passenger-car units.

Q3: Why is the cage material important in a hub bearing?

A: The cage separates and guides the rolling elements. Steel cages offer strength at high temperature, while polymer cages reduce noise and friction but may be more sensitive to heat and contamination.
