71900 CDGA/P4A 22 mm 10 mm 6 mm Frequently Asked Questions about 71900 CDGA/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 71900 CDGA/P4A over a 10 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.
The Open Type engineered for 71900 CDGA/P4A by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71900 CDGA/P4A with a precision bore diameter (d) of 10 mm, an outside diameter (D) of 22 mm, and a nominal ring width (B) of 6 mm. This configuration yields an effective cross-sectional wall thickness of 6.0 mm and an envelope ratio (D/d) of 2.2, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 71900 CDGA/P4A 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 10 mm bore. For the 22 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
