Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Standard batches of CHG Bearing 7200 CD/HCP4A conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
The Open Type engineered for 7200 CD/HCP4A by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7200 CD/HCP4A with a precision bore diameter (d) of 10 mm, an outside diameter (D) of 30 mm, and a nominal ring width (B) of 9 mm. This configuration yields an effective cross-sectional wall thickness of 10.0 mm and an envelope ratio (D/d) of 3.0, delivering compact rigidity for OEM machinery housings.
Every production batch of CHG Bearing 7200 CD/HCP4A Super-precision Angular Contact Ball Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
