Frequently Asked Questions about PAB080 PA Angular Contact Ball Series

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

The PAB080 utilizes high-purity bearing steel treated with PRS Bearings's advanced thermal processes. This creates a tough core that effectively absorbs shock loads while maintaining a highly wear-resistant surface on the raceways.
Every PAB080 batch undergoes 100% automated vibration and noise testing at the PRS Bearings factory. We guarantee compliance with Z1/V1 standards, with premium Z3/V3 options available for high-end electric motors.
The PRS Bearings PAB080 features precision-machined corner chamfers designed to facilitate easier mounting. These ISO-standard chamfers ensure that the PA Angular Contact Ball Series fits snugly against shaft shoulders, preventing stress concentration at the 203.2 mm bore interface.
Depending on your thermal and fit requirements, PRS Bearings supplies the PAB080 in C0 (Normal), C2 (Tight), or C3 (Loose) internal radial clearances. Proper clearance selection by PRS Bearings specialists helps prevent premature bearing seizure.
