Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Depending on your thermal and fit requirements, PRS Bearings supplies the PXB160 in C0 (Normal), C2 (Tight), or C3 (Loose) internal radial clearances. Proper clearance selection by PRS Bearings specialists helps prevent premature bearing seizure.
Yes, while the standard PRS Bearings PXB160 meets ISO P0 (ABEC-1) levels, PRS Bearings also manufactures high-precision variants in P6 (ABEC-3) and P5 (ABEC-5) for applications requiring minimal runout and extreme rotational accuracy.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PXB160. This lowers operating temperatures and power consumption, particularly when running near its 740 RPM threshold.
PRS Bearings provides a comprehensive B2B warranty for the PXB160 against manufacturing defects. Furthermore, our engineering team offers ongoing technical support to ensure the PX 4-Point Contact Ball Bearing operates optimally within your specific machinery.
