Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the 618/1180 Deep Groove Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 618/1180. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Engineered according to international ISO boundary plans, CHG Bearing supplies 618/1180 with a precision bore diameter (d) of 1180 mm, an outside diameter (D) of 1420 mm, and a nominal ring width (B) of 106 mm. This configuration yields an effective cross-sectional wall thickness of 120.0 mm and an envelope ratio (D/d) of 1.2, delivering compact rigidity for OEM machinery housings.
When fitting 618/1180 over a 1180 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.
