Cylindrical Roller Bearing 90 mm OD
Meritor

This radial-bearing element supports substantial loads with minimal friction, thanks to an arrangement of rollers aligned parallel to the axis. The cylindrical geometry optimizes contact area, distributing forces evenly and improving stiffness under heavy loads while reducing heat buildup during high-speed operation. The outer diameter and bore size define a robust housing interface and allow precise mounting with minimal runout, which is critical for maintaining alignment in hub assemblies and gear stages. The bearing’s lubrication pathway helps maintain a protective film between contacting surfaces, prolonging service life even in dirty or wet environments. The materials and heat treating chosen for this part resist wear and corrosion, enabling long intervals between maintenance activities. In practical use, reliable radial support reduces vibration, extending seal life and minimizing fretting at adjacent components. Operators benefit from steadier wheel performance, reduced maintenance costs, and fewer unscheduled repairs, especially on long-haul routes where uptime is a competitive advantage.
