HKC120XP4 323.85 mm 304.8 mm 9.525 mm Frequently Asked Questions about HKC120XP4 Thin Section Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects HKC120XP4 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Absolutely. The CHG Bearing HKC120XP4 Thin Section Four-Point Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HKC120XP4, FAG HKC120XP4, NSK HKC120XP4. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for HKC120XP4, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Each HKC120XP4 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 (304.8 mm bore side) ensures perfect planar contact without edge binding.
