71936 CD/P4ADBC 250 mm 180 mm 66 mm Frequently Asked Questions about 71936 CD/P4ADBC Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 71936 CD/P4ADBC, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Beyond standard alloy steel, CHG Bearing can customize the 71936 CD/P4ADBC Super-precision Angular Contact Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Model 71936 CD/P4ADBC is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 180 mm) and steep thermal gradients between inner and outer rings.
To ensure optimum performance of CHG Bearing 71936 CD/P4ADBC 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 180 mm bore. For the 250 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
