Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing 011.45.1800.03K directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Four-Point Contact Ball Slewing Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies 011.45.1800.03K with a precision bore diameter (d) of 1660 mm, an outside diameter (D) of 1940 mm, and a nominal ring width (B) of 140 mm. This configuration yields an effective cross-sectional wall thickness of 140.0 mm and an envelope ratio (D/d) of 1.17, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 011.45.1800.03K 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.
When fitting 011.45.1800.03K over a 1660 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.
