1797/2100G2K1 2600 mm 2100 mm 180 mm 2540 mm 2200 mm Frequently Asked Questions about 1797/2100G2K1 Crossed Roller Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects 1797/2100G2K1 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Engineered according to international ISO boundary plans, CHG Bearing supplies 1797/2100G2K1 with a precision bore diameter (d) of 2100 mm, an outside diameter (D) of 2600 mm, and a nominal ring width (B) of 180 mm. This configuration yields an effective cross-sectional wall thickness of 250.0 mm and an envelope ratio (D/d) of 1.24, delivering compact rigidity for OEM machinery housings.
For international ocean and air freight, CHG Bearing packs 1797/2100G2K1 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
When fitting 1797/2100G2K1 over a 2100 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.
