9.525 mm 476.25 mm 457.2 mm PRC180 Frequently Asked Questions about PRC180 PR Radial Contact Ball Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The standard PRS Bearings PRC180 is designed for rigid configurations. For optimal performance, strict alignment of the 457.2 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
PRS Bearings recommends storing the PRC180 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.
Depending on your thermal and fit requirements, PRS Bearings supplies the PRC180 in C0 (Normal), C2 (Tight), or C3 (Loose) internal radial clearances. Proper clearance selection by PRS Bearings specialists helps prevent premature bearing seizure.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PRC180. This lowers operating temperatures and power consumption, particularly when running near its 1,090 RPM threshold.
