7213 CD/P4A 120 mm 65 mm 23 mm Frequently Asked Questions about 7213 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 7213 CD/P4A with a precision bore diameter (d) of 65 mm, an outside diameter (D) of 120 mm, and a nominal ring width (B) of 23 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.
To safeguard CHG Bearing 7213 CD/P4A 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.
Every production batch of CHG Bearing 7213 CD/P4A 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.
To match diverse operational dynamics, CHG Bearing supplies 7213 CD/P4A with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
