FCDP78108320 540 mm 390 mm 431 mm 320 mm Frequently Asked Questions about FCDP78108320 Four-Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting FCDP78108320 over a 390 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 FCDP78108320 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (390 mm x 540 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
