PAD080 12.7 mm 228.6 mm 203.2 mm Frequently Asked Questions about PAD080 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 PAD080. This lowers operating temperatures and power consumption, particularly when running near its 2,350 RPM threshold.
The PRS Bearings PAD080 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.
PRS Bearings provides the PAD080 with various cage options including high-strength pressed steel, machined brass for high-vibration tasks, or reinforced polymers for the quietest operation in precision machinery.
The PAD080 is manufactured by PRS Bearings using premium-grade bearing steel that undergoes rigorous quality control processes. The company adheres to international standards including ISO 9001 and IATF 16949, ensuring consistent material purity and structural integrity across all production batches.
