1797/2500G2K2 2920 mm 2500 mm 260 mm 3060 mm 2622 mm Frequently Asked Questions about 1797/2500G2K2 Crossed Roller Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To extend the trouble-free lifespan of CHG Bearing 1797/2500G2K2, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
Each 1797/2500G2K2 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 (2500 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies 1797/2500G2K2 with a precision bore diameter (d) of 2500 mm, an outside diameter (D) of 2920 mm, and a nominal ring width (B) of 260 mm. This configuration yields an effective cross-sectional wall thickness of 210.0 mm and an envelope ratio (D/d) of 1.17, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 1797/2500G2K2 Crossed Roller Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 2500 mm bore. For the 2920 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
