718/710P4 870 mm 710 mm 74 mm Frequently Asked Questions about 718/710P4 Angular Contact Ball Bearings（718 / 719 SERIES）
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 718/710P4 over a 710 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.
Each 718/710P4 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (710 mm bore side) ensures perfect planar contact without edge binding.
To safeguard CHG Bearing 718/710P4 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (710 mm x 870 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
