HJA040XP0 114.3 mm 101.6 mm 6.35 mm Frequently Asked Questions about HJA040XP0 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 HJA040XP0 with a precision bore diameter (d) of 101.6 mm, an outside diameter (D) of 114.3 mm, and a nominal ring width (B) of 6.35 mm. This configuration yields an effective cross-sectional wall thickness of 6.4 mm and an envelope ratio (D/d) of 1.12, delivering compact rigidity for OEM machinery housings.
Each HJA040XP0 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 HJA040XP0 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.
The Sealed engineered for HJA040XP0 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
