7201 CD/P4A 32 mm 12 mm 10 mm Frequently Asked Questions about 7201 CD/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7201 CD/P4A with a precision bore diameter (d) of 12 mm, an outside diameter (D) of 32 mm, and a nominal ring width (B) of 10 mm. This configuration yields an effective cross-sectional wall thickness of 10.0 mm and an envelope ratio (D/d) of 2.67, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 7201 CD/P4A 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 12 mm bore. For the 32 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Each 7201 CD/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 (12 mm bore side) ensures perfect planar contact without edge binding.
Model 7201 CD/P4A 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 12 mm) and steep thermal gradients between inner and outer rings.
