Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The PRC140 produced by PRS Bearings adheres to strict ISO standards with a bore diameter of 355.6 mm, an outer diameter of 374.65 mm, and a width of 9.525 mm. PRS Bearings utilizes advanced grinding technology to ensure a radial section wall thickness of 9.5 mm and a balanced D/d ratio of 1.05 for high-precision housing fits.
Under optimal lubrication conditions, the PRS Bearings PRC140 can reach a limiting speed of 1,390 RPM. The low-friction raceway finish developed by PRS Bearings allows for cooler running temperatures even at high velocities.
The L10 life of the PRS Bearings PRC140 is calculated based on its 9,581 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.
Certainly. While the standard PRC140 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.
