Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing NJ28/530 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (530 mm x 650 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Standard batches of CHG Bearing NJ28/530 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
To ensure optimum performance of CHG Bearing NJ28/530 Single Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 530 mm bore. For the 650 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Engineered according to international ISO boundary plans, CHG Bearing supplies NJ28/530 with a precision bore diameter (d) of 530 mm, an outside diameter (D) of 650 mm, and a nominal ring width (B) of 72 mm. This configuration yields an effective cross-sectional wall thickness of 60.0 mm and an envelope ratio (D/d) of 1.23, delivering compact rigidity for OEM machinery housings.
