Frequently Asked Questions about HKC055XP0 Thin Section Four-Point 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 HKC055XP0 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.
Each HKC055XP0 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (139.7 mm bore side) ensures perfect planar contact without edge binding.
Built for demanding industrial environments, the HKC055XP0 Thin Section Four-Point 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.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for HKC055XP0, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
