896/892D 228.6 mm 136.525 mm Frequently Asked Questions about 896/892D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 896/892D is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 136.525 mm) and steep thermal gradients between inner and outer rings.
The CHG Bearing 896/892D 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.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 896/892D correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
To safeguard CHG Bearing 896/892D against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (136.525 mm x 228.6 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
