Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The PRS Bearings XRA 6008 features an advanced dual-sealing system with standard double seal (ds: 63.5) and double high-performance seal (Dh: 70.5) configurations. These specialized seals provide an effective barrier against dust, moisture, and contaminants, ensuring the internal raceways of the XRA 6008 remain uncontaminated. This significantly reduces maintenance costs and extends service life.
PRS Bearings provides the XRA 6008 with various cage options including high-strength pressed steel, machined brass for high-vibration tasks, or reinforced polymers for the quietest operation in precision machinery.
Yes, beyond standard ISO specifications, PRS Bearings can produce the XRA 6008 with tailored radial internal clearances and ultra-precision accuracy classes to meet the strict demands of specialized OEM applications.
The XRA 6008 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.
