Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The PRS Bearings XRBT305 features an advanced dual-sealing system with standard double seal (ds: 32.5) and double high-performance seal (Dh: 37) configurations. These specialized seals provide an effective barrier against dust, moisture, and contaminants, ensuring the internal raceways of the XRBT305 remain uncontaminated. This significantly reduces maintenance costs and extends service life.
PRS Bearings recommends storing the XRBT305 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 XRBT305 is designed for rigid configurations. For optimal performance, strict alignment of the 30 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
PRS Bearings provides a comprehensive B2B warranty for the XRBT305 against manufacturing defects. Furthermore, our engineering team offers ongoing technical support to ensure the Ultra Thin XRA-C Crossed Roller Bearings operates optimally within your specific machinery.
