12.7 mm 133.35 mm 114.3 mm PX045UU Frequently Asked Questions about PX045UU PX Sealed 4-Point Contact Ball Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To maximize the performance of the PX045UU, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 114.3 mm bore. For the 133.35 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
The standard PX045UU from PRS Bearings is heat-stabilized for temperatures up to 120°C. For extreme heat applications, PRS Bearings offers custom S1 or S2 stabilization treatments to ensure the component maintains its 114.3 mm x 133.35 mm dimensions without warping.
PRS Bearings recommends storing the PX045UU in its original packaging in a clean, low-vibration warehouse. Maintaining a relative humidity below 60% and a stable room temperature ensures maximum shelf life.
The PRS Bearings PX045UU features precision-machined corner chamfers designed to facilitate easier mounting. These ISO-standard chamfers ensure that the PX Sealed 4-Point Contact Ball Bearing fits snugly against shaft shoulders, preventing stress concentration at the 114.3 mm bore interface.
