Find key technical answers regarding dimensions, specifications, and replacement options for this model.
For international ocean and air freight, CHG Bearing packs 403Q002C 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.
Absolutely. The CHG Bearing 403Q002C Four-Point Contact Ball Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 403Q002C, FAG 403Q002C, NSK 403Q002C. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
When fitting 403Q002C over a 1701.825 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 403Q002C with a precision bore diameter (d) of 1701.825 mm, an outside diameter (D) of 2045.5 mm, and a nominal ring width (B) of 203.2 mm. This configuration yields an effective cross-sectional wall thickness of 171.8 mm and an envelope ratio (D/d) of 1.2, delivering compact rigidity for OEM machinery housings.
