Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Standard batches of CHG Bearing 7211 ACD/P4AQBCB 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 7211 ACD/P4AQBCB with a precision bore diameter (d) of 55 mm, an outside diameter (D) of 100 mm, and a nominal ring width (B) of 84 mm. This configuration yields an effective cross-sectional wall thickness of 22.5 mm and an envelope ratio (D/d) of 1.82, delivering compact rigidity for OEM machinery housings.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 7211 ACD/P4AQBCB. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
When fitting 7211 ACD/P4AQBCB over a 55 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
