Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 5397/2422 with a precision bore diameter (d) of 2422 mm, an outside diameter (D) of 2805 mm, and a nominal ring width (B) of 158 mm. This configuration yields an effective cross-sectional wall thickness of 191.5 mm and an envelope ratio (D/d) of 1.16, delivering compact rigidity for OEM machinery housings.
To extend the trouble-free lifespan of CHG Bearing 5397/2422, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
When fitting 5397/2422 over a 2422 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.
To safeguard CHG Bearing 5397/2422 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (2422 mm x 2805 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
