XRBU 405 73 mm 40 mm 5 mm Frequently Asked Questions about XRBU 405 XRBU Crossed Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Certainly. While the standard XRBU 405 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 XRBU 405 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 40 mm x 73 mm dimensions without warping.
The XRBU 405 utilizes high-purity bearing steel treated with PRS Bearings's advanced thermal processes. This creates a tough core that effectively absorbs shock loads while maintaining a highly wear-resistant surface on the raceways.
Yes, while the standard PRS Bearings XRBU 405 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.
