HKD140XP4 381 mm 355.6 mm 12.7 mm Frequently Asked Questions about HKD140XP4 Thin Section Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model HKD140XP4 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 355.6 mm) and steep thermal gradients between inner and outer rings.
Standard batches of CHG Bearing HKD140XP4 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.
Absolutely. The CHG Bearing HKD140XP4 Thin Section Four-Point Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HKD140XP4, FAG HKD140XP4, NSK HKD140XP4. 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 HKD140XP4 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.
