Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The PR075UU produced by PRS Bearings adheres to strict ISO standards with a bore diameter of 190.5 mm, an outer diameter of 209.55 mm, and a width of 12.7 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 1.1 for high-precision housing fits.
The PRS Bearings PR075UU features precision-machined corner chamfers designed to facilitate easier mounting. These ISO-standard chamfers ensure that the PR Sealed Radial Contact Ball Bearing fits snugly against shaft shoulders, preventing stress concentration at the 190.5 mm bore interface.
The L10 life of the PRS Bearings PR075UU is calculated based on its 7,120 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.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PR075UU. This lowers operating temperatures and power consumption, particularly when running near its 860 RPM threshold.
