Frequently Asked Questions about PAC090 PA Angular Contact Ball Series

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

The PRS Bearings PAC090 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 228.6 mm bore interface.
Engineered for heavy-duty endurance, the PRS Bearings PAC090 offers a dynamic load rating (Cr) of 8,105 and a static load rating (Cor) of 24,554. These ratings reflect PRS Bearings's commitment to using high-fatigue-strength materials for demanding radial and axial force environments.
To maximize the performance of the PAC090, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 228.6 mm bore. For the 247.65 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
The PAC090 produced by PRS Bearings adheres to strict ISO standards with a bore diameter of 228.6 mm, an outer diameter of 247.65 mm, and a width of 9.525 mm. PRS Bearings utilizes advanced grinding technology to ensure a radial section wall thickness of 9.5 mm and a balanced D/d ratio of 1.08 for high-precision housing fits.
