Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 61818, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Engineered according to international ISO boundary plans, CHG Bearing supplies 61818 with a precision bore diameter (d) of 90 mm, an outside diameter (D) of 115 mm, and a nominal ring width (B) of 13 mm. This configuration yields an effective cross-sectional wall thickness of 12.5 mm and an envelope ratio (D/d) of 1.28, delivering compact rigidity for OEM machinery housings.
The CHG Bearing 61818 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
To safeguard CHG Bearing 61818 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (90 mm x 115 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
