Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Depending on your thermal and fit requirements, PRS Bearings supplies the XRE11012 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 XRE11012 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 XRE11012 produced by PRS Bearings adheres to strict ISO standards with a bore diameter of 110 mm, an outer diameter of 135 mm, and a width of 12 mm. PRS Bearings utilizes advanced grinding technology to ensure a radial section wall thickness of 12.5 mm and a balanced D/d ratio of 1.23 for high-precision housing fits.
To maximize the performance of the XRE11012, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 110 mm bore. For the 135 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
