71917 ACE/HCP4ALDGA 120 mm 85 mm 36 mm Frequently Asked Questions about 71917 ACE/HCP4ALDGA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open Type), CHG Bearing pre-charges 71917 ACE/HCP4ALDGA 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.
Each 71917 ACE/HCP4ALDGA 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 (85 mm bore side) ensures perfect planar contact without edge binding.
The Open Type engineered for 71917 ACE/HCP4ALDGA 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.
Absolutely. The CHG Bearing 71917 ACE/HCP4ALDGA Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 71917 ACE/HCP4ALDGA, FAG 71917 ACE/HCP4ALDGA, NSK 71917 ACE/HCP4ALDGA. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
