19.05 mm 215 900 mm 177.8 mm PXF070 Frequently Asked Questions about PXF070 PX 4-Point Contact Ball Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The PRS Bearings PXF070 features precision-machined corner chamfers designed to facilitate easier mounting. These ISO-standard chamfers ensure that the PX 4-Point Contact Ball Bearing fits snugly against shaft shoulders, preventing stress concentration at the 177.8 mm bore interface.
The PXF070 utilizes high-purity bearing steel treated with PRS Bearings's advanced thermal processes. This creates a tough core that effectively absorbs shock loads while maintaining a highly wear-resistant surface on the raceways.
Yes. As part of our B2B commitment, if a PXF070 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.
The PXF070 is engineered with an optimal strength-to-mass ratio. PRS Bearings ensures that the cross-sectional distribution provides maximum structural rigidity for its 27,147 dynamic load rating without introducing excessive rotational inertia.
