12.7 mm 279.4 mm 254 mm PXD100 Frequently Asked Questions about PXD100 PX 4-Point Contact Ball Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The PRS Bearings PXD100 features precision-machined corner chamfers designed to facilitate easier mounting. These ISO-standard chamfers ensure that the PX 4-Point Contact Ball Bearing fits snugly against shaft shoulders, preventing stress concentration at the 254 mm bore interface.
Depending on your thermal and fit requirements, PRS Bearings supplies the PXD100 in C0 (Normal), C2 (Tight), or C3 (Loose) internal radial clearances. Proper clearance selection by PRS Bearings specialists helps prevent premature bearing seizure.
Certainly. While the standard PXD100 is pre-filled with high-grade industrial lubricant, PRS Bearings can provide custom fills, including food-grade (NSF H1), high-temperature, or extreme-pressure greases tailored to your operational needs.
Yes, while the standard PRS Bearings PXD100 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.
