Frequently Asked Questions about PRF400 PR Radial Contact Ball Bearing

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

The PRF400 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 standard PRF400 from PRS Bearings is heat-stabilized for temperatures up to 120°C. For extreme heat applications, PRS Bearings offers custom S1 or S2 stabilization treatments to ensure the component maintains its 1016 mm x 1054.1 mm dimensions without warping.
Absolutely. The precise manufacturing of the PRS Bearings PRF400 results in stable, predictable vibration baselines. This makes it highly compatible with modern IoT condition monitoring sensors for early fault detection.
Every PRS Bearings PRF400 is treated with premium rust-preventative oil and vacuum-sealed or wrapped in VCI paper. This guarantees that the 1016 mm bore and 1054.1 mm outer surfaces remain pristine during overseas transit.
