Find key technical answers regarding dimensions, specifications, and replacement options for this model.
PRS Bearings provides a comprehensive B2B warranty for the XRT130-NT against manufacturing defects. Furthermore, our engineering team offers ongoing technical support to ensure the XRT Series Crossed Tapered Roller Bearings operates optimally within your specific machinery.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the XRT130-NT. This lowers operating temperatures and power consumption, particularly when running near its 620 RPM threshold.
Certainly. While the standard XRT130-NT 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.
Under optimal lubrication conditions, the PRS Bearings XRT130-NT can reach a limiting speed of 620 RPM. The low-friction raceway finish developed by PRS Bearings allows for cooler running temperatures even at high velocities.
