Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, PRS Bearings is a leading OEM partner. We offer bulk B2B pricing for the PXC040, along with custom laser marking, specialized packaging, and technical documentation (MTR/COC) tailored to your company's requirements.
Depending on your thermal and fit requirements, PRS Bearings supplies the PXC040 in C0 (Normal), C2 (Tight), or C3 (Loose) internal radial clearances. Proper clearance selection by PRS Bearings specialists helps prevent premature bearing seizure.
To maximize the performance of the PXC040, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 101.6 mm bore. For the 120.65 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 PXC040 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 101.6 mm x 120.65 mm dimensions without warping.
