Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The PRS Bearings XRBT155 is a drop-in replacement for international models like RAU1505. It follows universal ISO dimensions, making it easy to upgrade your supply chain to PRS Bearings's high-quality standards.
Yes, while the standard PRS Bearings XRBT155 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.
PRS Bearings recommends storing the XRBT155 in its original packaging in a clean, low-vibration warehouse. Maintaining a relative humidity below 60% and a stable room temperature ensures maximum shelf life.
The standard PRS Bearings XRBT155 is designed for rigid configurations. For optimal performance, strict alignment of the 15 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
