HKB040XP4 117.475 mm 101.6 mm 7.9375 mm Frequently Asked Questions about HKB040XP4 Thin Section Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing HKB040XP4 Thin Section Four-Point Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HKB040XP4, FAG HKB040XP4, NSK HKB040XP4. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Beyond standard alloy steel, CHG Bearing can customize the HKB040XP4 Thin Section Four-Point Contact Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Each HKB040XP4 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 (101.6 mm bore side) ensures perfect planar contact without edge binding.
Model HKB040XP4 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 101.6 mm) and steep thermal gradients between inner and outer rings.
