Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The XRB 18025 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.
To maximize the performance of the XRB 18025, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 180 mm bore. For the 240 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
Certainly. While the standard XRB 18025 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.
Yes, PRS Bearings strictly adheres to global environmental directives. The bearing steel and industrial lubricants used in the XRB 18025 are formulated to meet international safety standards, ensuring eco-friendly equipment integration.
