Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46284A with a precision bore diameter (d) of 420 mm, an outside diameter (D) of 620 mm, and a nominal ring width (B) of 188 mm. This configuration yields an effective cross-sectional wall thickness of 100.0 mm and an envelope ratio (D/d) of 1.48, delivering compact rigidity for OEM machinery housings.
For international ocean and air freight, CHG Bearing packs 46284A 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.
As standard production, CHG Bearing subjects 46284A 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.
Standard batches of CHG Bearing 46284A conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
