Frequently Asked Questions about PXA040 PX 4-Point Contact Ball Bearing

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

Under optimal lubrication conditions, the PRS Bearings PXA040 can reach a limiting speed of 2,820 RPM. The low-friction raceway finish developed by PRS Bearings allows for cooler running temperatures even at high velocities.
Every PXA040 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 PXA040 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.
Depending on your thermal and fit requirements, PRS Bearings supplies the PXA040 in C0 (Normal), C2 (Tight), or C3 (Loose) internal radial clearances. Proper clearance selection by PRS Bearings specialists helps prevent premature bearing seizure.
