Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 719/1220X3/DF over a 1220 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.
