024.30.800 898 mm 702 mm 124 mm 658 mm 942 mm Frequently Asked Questions about 024.30.800 Double-Row Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of 024.30.800 Double-Row Ball 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 024.30.800 Double-Row Ball Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 658 mm bore. For the 942 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
In its sealed configuration (Open Type), CHG Bearing pre-charges 024.30.800 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
Each 024.30.800 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 (658 mm bore side) ensures perfect planar contact without edge binding.
