PAG055 25.4 mm 190.5 mm 139.7 mm Frequently Asked Questions about PAG055 PA Angular Contact Ball Series
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Under optimal lubrication conditions, the PRS Bearings PAG055 can reach a limiting speed of 3,080 RPM. The low-friction raceway finish developed by PRS Bearings allows for cooler running temperatures even at high velocities.
Absolutely. The PRS Bearings PAG055 is a drop-in replacement for international models like KAYDON KG055AR0, SILVERTHIN SG055AR0. It follows universal ISO dimensions, making it easy to upgrade your supply chain to PRS Bearings's high-quality standards.
Certainly. While the standard PAG055 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.
The PAG055 is engineered with an optimal strength-to-mass ratio. PRS Bearings ensures that the cross-sectional distribution provides maximum structural rigidity for its 31,992 dynamic load rating without introducing excessive rotational inertia.
