463/800 1280 mm 800 mm Frequently Asked Questions about 463/800 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 463/800 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (800 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies 463/800 with a precision bore diameter (d) of 800 mm, an outside diameter (D) of 1280 mm, and a nominal ring width (B) of 375 mm. This configuration yields an effective cross-sectional wall thickness of 240.0 mm and an envelope ratio (D/d) of 1.6, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 463/800 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (800 mm x 1280 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Absolutely. The CHG Bearing 463/800 Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 463/800, FAG 463/800, NSK 463/800. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
