7022 ACD/P4ATBTB 170 mm 110 mm 84 mm Frequently Asked Questions about 7022 ACD/P4ATBTB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 7022 ACD/P4ATBTB 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 (110 mm bore side) ensures perfect planar contact without edge binding.
In its sealed configuration (Open Type), CHG Bearing pre-charges 7022 ACD/P4ATBTB with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
To ensure optimum performance of CHG Bearing 7022 ACD/P4ATBTB Super-precision Angular Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 110 mm bore. For the 170 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
To safeguard CHG Bearing 7022 ACD/P4ATBTB against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (110 mm x 170 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
