PAG045 25.4 mm 165.1 mm 114.3 mm Frequently Asked Questions about PAG045 PA Angular Contact Ball Series
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
PRS Bearings provides the PAG045 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.
Every PRS Bearings PAG045 is treated with premium rust-preventative oil and vacuum-sealed or wrapped in VCI paper. This guarantees that the 114.3 mm bore and 165.1 mm outer surfaces remain pristine during overseas transit.
PRS Bearings provides a comprehensive B2B warranty for the PAG045 against manufacturing defects. Furthermore, our engineering team offers ongoing technical support to ensure the PA Angular Contact Ball Series operates optimally within your specific machinery.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PAG045. This lowers operating temperatures and power consumption, particularly when running near its 3,640 RPM threshold.
