Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting N2344 over a 220 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 N2344 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 N2344 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.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for N2344, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
