Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing 332169A-1 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.
Standard batches of CHG Bearing 332169A-1 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
Absolutely. The CHG Bearing 332169A-1 Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 332169A-1, FAG 332169A-1, NSK 332169A-1. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
To safeguard CHG Bearing 332169A-1 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (305.07 mm x 500 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
