010.45.1800.12 1940 mm 1660 mm 110 mm 1802 mm 1887 mm Frequently Asked Questions about 010.45.1800.12 Four-Point Contact Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 010.45.1800.12 Four-Point Contact Ball Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 1660 mm bore. For the 1940 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 010.45.1800.12 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.
Absolutely. The CHG Bearing 010.45.1800.12 Four-Point Contact Ball Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 010.45.1800.12, FAG 010.45.1800.12, NSK 010.45.1800.12.
