K-80385/325P5 533.4 mm 431.8 mm N/A mm Frequently Asked Questions about K-80385/325P5 Single Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing K-80385/325P5 Single Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF K-80385/325P5, FAG K-80385/325P5, NSK K-80385/325P5. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
To safeguard CHG Bearing K-80385/325P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (431.8 mm x 533.4 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
The CHG Bearing K-80385/325P5 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.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for K-80385/325P5, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
