Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 1797/2635G over a 2635 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 1797/2635G against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (2635 mm x 3332 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
