Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 7216 CD/P4ADGD. 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 7216 CD/P4ADGD over a 80 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.
Each 7216 CD/P4ADGD produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (80 mm bore side) ensures perfect planar contact without edge binding.
As standard production, CHG Bearing subjects 7216 CD/P4ADGD to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
