PAA065 6.35 mm 177.8 mm 165.1 mm Frequently Asked Questions about PAA065 PA Angular Contact Ball Series
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PAA065. This lowers operating temperatures and power consumption, particularly when running near its 2,960 RPM threshold.
Yes. As part of our B2B commitment, if a PAA065 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.
PRS Bearings recommends storing the PAA065 in its original packaging in a clean, low-vibration warehouse. Maintaining a relative humidity below 60% and a stable room temperature ensures maximum shelf life.
The standard PRS Bearings PAA065 is designed for rigid configurations. For optimal performance, strict alignment of the 165.1 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
