71802 CD/P4DGA 24 mm 15 mm 10 mm Frequently Asked Questions about 71802 CD/P4DGA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 71802 CD/P4DGA over a 15 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.
To ensure optimum performance of CHG Bearing 71802 CD/P4DGA Super-precision Angular Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 15 mm bore. For the 24 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
To safeguard CHG Bearing 71802 CD/P4DGA against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (15 mm x 24 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 71802 CD/P4DGA with a precision bore diameter (d) of 15 mm, an outside diameter (D) of 24 mm, and a nominal ring width (B) of 10 mm. This configuration yields an effective cross-sectional wall thickness of 4.5 mm and an envelope ratio (D/d) of 1.6, delivering compact rigidity for OEM machinery housings.
