HKC055AP0 158.75 mm 139.7 mm 9.525 mm Frequently Asked Questions about HKC055AP0 Thin Section Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies HKC055AP0 with a precision bore diameter (d) of 139.7 mm, an outside diameter (D) of 158.75 mm, and a nominal ring width (B) of 9.525 mm. This configuration yields an effective cross-sectional wall thickness of 9.5 mm and an envelope ratio (D/d) of 1.14, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing HKC055AP0 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 139.7 mm bore. For the 158.75 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Built for demanding industrial environments, the HKC055AP0 Thin Section Angular Contact Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
To safeguard CHG Bearing HKC055AP0 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (139.7 mm x 158.75 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
