Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 1797/1100G Crossed Roller Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 1100 mm bore. For the 1415 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Quality starts with raw material selection: CHG Bearing crafts 1797/1100G inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Engineered according to international ISO boundary plans, CHG Bearing supplies 1797/1100G with a precision bore diameter (d) of 1100 mm, an outside diameter (D) of 1415 mm, and a nominal ring width (B) of 115 mm. This configuration yields an effective cross-sectional wall thickness of 157.5 mm and an envelope ratio (D/d) of 1.29, delivering compact rigidity for OEM machinery housings.
For international ocean and air freight, CHG Bearing packs 1797/1100G 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.
