Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing 010.45.1284.12 Four-Point Contact Ball Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 010.45.1284.12, FAG 010.45.1284.12, NSK 010.45.1284.12. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each 010.45.1284.12 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 (1150 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies 010.45.1284.12 with a precision bore diameter (d) of 1150 mm, an outside diameter (D) of 1410 mm, and a nominal ring width (B) of 110 mm. This configuration yields an effective cross-sectional wall thickness of 130.0 mm and an envelope ratio (D/d) of 1.23, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 010.45.1284.12 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (1150 mm x 1410 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
