Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing S7213 ACDGB/P4A is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Model S7213 ACDGB/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 65 mm) and steep thermal gradients between inner and outer rings.
Engineered according to international ISO boundary plans, CHG Bearing supplies S7213 ACDGB/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.
Standard batches of CHG Bearing S7213 ACDGB/P4A 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.
