Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The XRA12008C 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.
Absolutely. The PRS Bearings XRA12008C is a drop-in replacement for international models like THK RA12008C. It follows universal ISO dimensions, making it easy to upgrade your supply chain to PRS Bearings's high-quality standards.
Certainly. While the standard XRA12008C 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.
To maximize the performance of the XRA12008C, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 120 mm bore. For the 136 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
