HKA047AP0 133.35 mm 120.65 mm 6.35 mm Frequently Asked Questions about HKA047AP0 Thin Section Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Standard batches of CHG Bearing HKA047AP0 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 HKA047AP0 Thin Section Angular Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 120.65 mm bore. For the 133.35 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 HKA047AP0 with a precision bore diameter (d) of 120.65 mm, an outside diameter (D) of 133.35 mm, and a nominal ring width (B) of 6.35 mm. This configuration yields an effective cross-sectional wall thickness of 6.3 mm and an envelope ratio (D/d) of 1.11, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing HKA047AP0 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (120.65 mm x 133.35 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
