Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The PXG070 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.
The L10 life of the PRS Bearings PXG070 is calculated based on its 45,407 dynamic capacity and your specific application loads. By maintaining clean operating conditions and using PRS Bearings's recommended lubrication, users can expect significantly extended service intervals.
Every PRS Bearings PXG070 is treated with premium rust-preventative oil and vacuum-sealed or wrapped in VCI paper. This guarantees that the 177.8 mm bore and 228.6 mm outer surfaces remain pristine during overseas transit.
Under optimal lubrication conditions, the PRS Bearings PXG070 can reach a limiting speed of 1,500 RPM. The low-friction raceway finish developed by PRS Bearings allows for cooler running temperatures even at high velocities.
