HKS07403XS0 80 mm 74 mm 2.5 mm Frequently Asked Questions about HKS07403XS0 Super Thin Section Four-point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing HKS07403XS0 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (74 mm x 80 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Absolutely. The CHG Bearing HKS07403XS0 Super Thin Section Four-point Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HKS07403XS0, FAG HKS07403XS0, NSK HKS07403XS0. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
In its sealed configuration (Open Type), CHG Bearing pre-charges HKS07403XS0 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
To ensure optimum performance of CHG Bearing HKS07403XS0 Super Thin Section Four-point Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 74 mm bore. For the 80 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
