9.525 mm 374.65 mm 355.6 mm PXC140 Frequently Asked Questions about PXC140 PX 4-Point Contact Ball Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To maximize the performance of the PXC140, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 355.6 mm bore. For the 374.65 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PXC140. This lowers operating temperatures and power consumption, particularly when running near its 830 RPM threshold.
The standard PXC140 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 355.6 mm x 374.65 mm dimensions without warping.
Yes. As part of our B2B commitment, if a PXC140 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.
