Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 7210 ACD/HCP4ATBTA 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 (50 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7210 ACD/HCP4ATBTA with a precision bore diameter (d) of 50 mm, an outside diameter (D) of 90 mm, and a nominal ring width (B) of 60 mm. This configuration yields an effective cross-sectional wall thickness of 20.0 mm and an envelope ratio (D/d) of 1.8, delivering compact rigidity for OEM machinery housings.
To extend the trouble-free lifespan of CHG Bearing 7210 ACD/HCP4ATBTA, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
Model 7210 ACD/HCP4ATBTA 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 50 mm) and steep thermal gradients between inner and outer rings.
