S7213 CD/P4ADGA 120 mm 65 mm 46 mm Frequently Asked Questions about S7213 CD/P4ADGA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of S7213 CD/P4ADGA Super-precision Angular Contact Ball Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
To safeguard CHG Bearing S7213 CD/P4ADGA against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (65 mm x 120 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Standard batches of CHG Bearing S7213 CD/P4ADGA 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies S7213 CD/P4ADGA with a precision bore diameter (d) of 65 mm, an outside diameter (D) of 120 mm, and a nominal ring width (B) of 46 mm. This configuration yields an effective cross-sectional wall thickness of 27.5 mm and an envelope ratio (D/d) of 1.85, delivering compact rigidity for OEM machinery housings.
