Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Under optimal lubrication conditions, the PRS Bearings PXC055 can reach a limiting speed of 2,040 RPM. The low-friction raceway finish developed by PRS Bearings allows for cooler running temperatures even at high velocities.
Certainly. While the standard PXC055 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.
Depending on your thermal and fit requirements, PRS Bearings supplies the PXC055 in C0 (Normal), C2 (Tight), or C3 (Loose) internal radial clearances. Proper clearance selection by PRS Bearings specialists helps prevent premature bearing seizure.
Yes, while the standard PRS Bearings PXC055 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.
