PAA035 6.35 mm 101.6 mm 88.9 mm Frequently Asked Questions about PAA035 PA Angular Contact Ball Series
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The standard PRS Bearings PAA035 is designed for rigid configurations. For optimal performance, strict alignment of the 88.9 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
Depending on your thermal and fit requirements, PRS Bearings supplies the PAA035 in C0 (Normal), C2 (Tight), or C3 (Loose) internal radial clearances. Proper clearance selection by PRS Bearings specialists helps prevent premature bearing seizure.
The PRS Bearings PAA035 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 88.9 mm bore interface.
Engineered for heavy-duty endurance, the PRS Bearings PAA035 offers a dynamic load rating (Cr) of 2,455 and a static load rating (Cor) of 5,827. These ratings reflect PRS Bearings's commitment to using high-fatigue-strength materials for demanding radial and axial force environments.
