Find key technical answers regarding dimensions, specifications, and replacement options for this model.
PRS Bearings provides a comprehensive B2B warranty for the PXG045 against manufacturing defects. Furthermore, our engineering team offers ongoing technical support to ensure the PX 4-Point Contact Ball Bearing operates optimally within your specific machinery.
The L10 life of the PRS Bearings PXG045 is calculated based on its 36,498 dynamic capacity and your specific application loads. By maintaining clean operating conditions and using PRS Bearings's recommended lubrication, users can expect significantly extended service intervals.
To maximize the performance of the PXG045, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 114.3 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 PRS Bearings PXG045 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 114.3 mm bore interface.
