010.45.1400.12K 1540 mm 1260 mm 110 mm 1313 mm 1487 mm Frequently Asked Questions about 010.45.1400.12K Four-Point Contact Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 010.45.1400.12K over a 1260 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
To ensure optimum performance of CHG Bearing 010.45.1400.12K 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 1260 mm bore. For the 1540 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Engineered according to international ISO boundary plans, CHG Bearing supplies 010.45.1400.12K with a precision bore diameter (d) of 1260 mm, an outside diameter (D) of 1540 mm, and a nominal ring width (B) of 110 mm. This configuration yields an effective cross-sectional wall thickness of 140.0 mm and an envelope ratio (D/d) of 1.22, delivering compact rigidity for OEM machinery housings.
In its sealed configuration (Open Type), CHG Bearing pre-charges 010.45.1400.12K 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.
