Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 014.50.2650.03 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 2408 mm bore. For the 2835 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
For international ocean and air freight, CHG Bearing packs 014.50.2650.03 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 014.50.2650.03 with a precision bore diameter (d) of 2408 mm, an outside diameter (D) of 2835 mm, and a nominal ring width (B) of 155 mm. This configuration yields an effective cross-sectional wall thickness of 213.5 mm and an envelope ratio (D/d) of 1.18, delivering compact rigidity for OEM machinery housings.
In its sealed configuration (Open Type), CHG Bearing pre-charges 014.50.2650.03 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.
