7022 CD/P4ATBTA 170 mm 110 mm 84 mm Frequently Asked Questions about 7022 CD/P4ATBTA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects 7022 CD/P4ATBTA 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.
Model 7022 CD/P4ATBTA 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.
To ensure optimum performance of CHG Bearing 7022 CD/P4ATBTA 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.
Absolutely. The CHG Bearing 7022 CD/P4ATBTA Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 7022 CD/P4ATBTA, FAG 7022 CD/P4ATBTA, NSK 7022 CD/P4ATBTA. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
