Frequently Asked Questions about PXF180 PX 4-Point Contact Ball Bearing

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

As a dedicated bearing manufacturer, PRS Bearings maintains strategic inventory of the PXF180 for prompt dispatch. For large OEM forecast orders, our lean production lines guarantee highly competitive lead times.
Yes, while the standard PRS Bearings PXF180 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.
To maximize the performance of the PXF180, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 457.2 mm bore. For the 495.3 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
Yes, beyond standard ISO specifications, PRS Bearings can produce the PXF180 with tailored radial internal clearances and ultra-precision accuracy classes to meet the strict demands of specialized OEM applications.
