708 CEGB/P4A 22 mm 8 mm 7 mm Frequently Asked Questions about 708 CEGB/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 708 CEGB/P4A over a 8 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 708 CEGB/P4A with a precision bore diameter (d) of 8 mm, an outside diameter (D) of 22 mm, and a nominal ring width (B) of 7 mm. This configuration yields an effective cross-sectional wall thickness of 7.0 mm and an envelope ratio (D/d) of 2.75, delivering compact rigidity for OEM machinery housings.
Each 708 CEGB/P4A 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 (8 mm bore side) ensures perfect planar contact without edge binding.
Every production batch of CHG Bearing 708 CEGB/P4A Super-precision Angular Contact Ball Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
