Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered for heavy-duty endurance, the PRS Bearings XRSU168 offers a dynamic load rating (Cr) of 41.4 and a static load rating (Cor) of 119. These ratings reflect PRS Bearings's commitment to using high-fatigue-strength materials for demanding radial and axial force environments.
Depending on your thermal and fit requirements, PRS Bearings supplies the XRSU168 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 XRSU168 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.
The L10 life of the PRS Bearings XRSU168 is calculated based on its 41.4 dynamic capacity and your specific application loads. By maintaining clean operating conditions and using PRS Bearings's recommended lubrication, users can expect significantly extended service intervals.
