6.35 mm 241.3 mm 228.6 mm PRA090 Frequently Asked Questions about PRA090 PR Radial Contact Ball Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The PRA090 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.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PRA090. This lowers operating temperatures and power consumption, particularly when running near its 2,160 RPM threshold.
The standard PRA090 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 228.6 mm x 241.3 mm dimensions without warping.
Absolutely. The PRS Bearings PRA090 is a drop-in replacement for international models like KAYDON KA090CP0, SILVERTHIN SA090CP0. It follows universal ISO dimensions, making it easy to upgrade your supply chain to PRS Bearings's high-quality standards.
