Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 110.15.730.03 with a precision bore diameter (d) of 654.05 mm, an outside diameter (D) of 812.038 mm, and a nominal ring width (B) of 55.88 mm. This configuration yields an effective cross-sectional wall thickness of 79.0 mm and an envelope ratio (D/d) of 1.24, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 110.15.730.03 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (654.05 mm x 812.038 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
To ensure optimum performance of CHG Bearing 110.15.730.03 Crossed Roller Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 654.05 mm bore. For the 812.038 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Every production batch of CHG Bearing 110.15.730.03 Crossed Roller Slewing Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
