Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The PRS Bearings PXB070 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.
To maximize the performance of the PXB070, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 177.8 mm bore. For the 193.675 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
