Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To maximize the performance of the PX14008UU, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 140 mm bore. For the 156 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 PRS Bearings PX14008UU is designed for rigid configurations. For optimal performance, strict alignment of the 140 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
Yes, beyond standard ISO specifications, PRS Bearings can produce the PX14008UU with tailored radial internal clearances and ultra-precision accuracy classes to meet the strict demands of specialized OEM applications.
PRS Bearings provides a comprehensive B2B warranty for the PX14008UU against manufacturing defects. Furthermore, our engineering team offers ongoing technical support to ensure the X Type Four Point Contact Ball Bearing operates optimally within your specific machinery.
