46256 420 mm 280 mm Frequently Asked Questions about 46256 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46256 with a precision bore diameter (d) of 280 mm, an outside diameter (D) of 420 mm, and a nominal ring width (B) of 106 mm. This configuration yields an effective cross-sectional wall thickness of 70.0 mm and an envelope ratio (D/d) of 1.5, delivering compact rigidity for OEM machinery housings.
Every production batch of CHG Bearing 46256 Double Row Tapered Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
When fitting 46256 over a 280 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.
For international ocean and air freight, CHG Bearing packs 46256 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.
