Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 2797/1010G2 Crossed Roller Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 1010 mm bore. For the 1200 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Engineered according to international ISO boundary plans, CHG Bearing supplies 2797/1010G2 with a precision bore diameter (d) of 1010 mm, an outside diameter (D) of 1200 mm, and a nominal ring width (B) of 90 mm. This configuration yields an effective cross-sectional wall thickness of 95.0 mm and an envelope ratio (D/d) of 1.19, delivering compact rigidity for OEM machinery housings.
Each 2797/1010G2 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 (1010 mm bore side) ensures perfect planar contact without edge binding.
Model 2797/1010G2 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 1010 mm) and steep thermal gradients between inner and outer rings.
