Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects 1797/2635 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Each 1797/2635 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 (2635 mm bore side) ensures perfect planar contact without edge binding.
To safeguard CHG Bearing 1797/2635 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (2635 mm x 3440 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Absolutely. The CHG Bearing 1797/2635 Crossed Roller Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 1797/2635, FAG 1797/2635, NSK 1797/2635.
