Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 7207 CD/P4AQBTB against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (35 mm x 72 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7207 CD/P4AQBTB with a precision bore diameter (d) of 35 mm, an outside diameter (D) of 72 mm, and a nominal ring width (B) of 68 mm. This configuration yields an effective cross-sectional wall thickness of 18.5 mm and an envelope ratio (D/d) of 2.06, delivering compact rigidity for OEM machinery housings.
When fitting 7207 CD/P4AQBTB over a 35 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.
As standard production, CHG Bearing subjects 7207 CD/P4AQBTB 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.
