25.4 mm 558.8 mm 508 mm PXG200 Frequently Asked Questions about PXG200 PX 4-Point Contact Ball Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, while the standard PRS Bearings PXG200 meets ISO P0 (ABEC-1) levels, PRS Bearings also manufactures high-precision variants in P6 (ABEC-3) and P5 (ABEC-5) for applications requiring minimal runout and extreme rotational accuracy.
PRS Bearings recommends storing the PXG200 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.
To maximize the performance of the PXG200, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 508 mm bore. For the 558.8 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
Depending on your thermal and fit requirements, PRS Bearings supplies the PXG200 in C0 (Normal), C2 (Tight), or C3 (Loose) internal radial clearances. Proper clearance selection by PRS Bearings specialists helps prevent premature bearing seizure.
