Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of 1797/3230GK5 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 1797/3230GK5 Crossed Roller Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 3230 mm bore. For the 4100 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Model 1797/3230GK5 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 3230 mm) and steep thermal gradients between inner and outer rings.
Engineered according to international ISO boundary plans, CHG Bearing supplies 1797/3230GK5 with a precision bore diameter (d) of 3230 mm, an outside diameter (D) of 4100 mm, and a nominal ring width (B) of 240 mm. This configuration yields an effective cross-sectional wall thickness of 435.0 mm and an envelope ratio (D/d) of 1.27, delivering compact rigidity for OEM machinery housings.
