Frequently Asked Questions about PAB020 PA Angular Contact Ball Series

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

Engineered for heavy-duty endurance, the PRS Bearings PAB020 offers a dynamic load rating (Cr) of 2,673 and a static load rating (Cor) of 4,849. These ratings reflect PRS Bearings's commitment to using high-fatigue-strength materials for demanding radial and axial force environments.
The standard PRS Bearings PAB020 is designed for rigid configurations. For optimal performance, strict alignment of the 50.8 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
Yes. As part of our B2B commitment, if a PAB020 experiences unexpected issues in the field, PRS Bearings engineers can perform detailed metallurgical and wear analysis to identify root causes and optimize your future setups.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PAB020. This lowers operating temperatures and power consumption, particularly when running near its 8,650 RPM threshold.
