Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing 2797/760G2 Crossed Roller Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 2797/760G2, FAG 2797/760G2, NSK 2797/760G2. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Model 2797/760G2 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 760 mm) and steep thermal gradients between inner and outer rings.
Yes, 100% of 2797/760G2 Crossed Roller Slewing Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
To ensure optimum performance of CHG Bearing 2797/760G2 Crossed Roller Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 760 mm bore. For the 1000 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
