PAF050 19.05 mm 165.1 mm 127 mm Frequently Asked Questions about PAF050 PA Angular Contact Ball Series
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
PRS Bearings recommends storing the PAF050 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.
To maximize the performance of the PAF050, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 127 mm bore. For the 165.1 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
The PAF050 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.
The PRS Bearings PAF050 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 127 mm bore interface.
