Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The standard PRS Bearings XRB 50025 is designed for rigid configurations. For optimal performance, strict alignment of the 500 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
Certainly. While the standard XRB 50025 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.
The standard XRB 50025 from PRS Bearings is heat-stabilized for temperatures up to 120°C. For extreme heat applications, PRS Bearings offers custom S1 or S2 stabilization treatments to ensure the component maintains its 500 mm x 550 mm dimensions without warping.
Every PRS Bearings XRB 50025 is treated with premium rust-preventative oil and vacuum-sealed or wrapped in VCI paper. This guarantees that the 500 mm bore and 550 mm outer surfaces remain pristine during overseas transit.
