7022 ACE/HCP4ALDT 170 mm 110 mm 56 mm Frequently Asked Questions about 7022 ACE/HCP4ALDT Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 7022 ACE/HCP4ALDT is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 110 mm) and steep thermal gradients between inner and outer rings.
As standard production, CHG Bearing subjects 7022 ACE/HCP4ALDT to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 7022 ACE/HCP4ALDT, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Each 7022 ACE/HCP4ALDT 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.
