Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for 89180 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.
In its sealed configuration (Open Type), CHG Bearing pre-charges 89180 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.
Absolutely. The CHG Bearing 89180 Cylindrical Roller Thrust Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 89180, FAG 89180, NSK 89180. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each 89180 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 (400 mm bore side) ensures perfect planar contact without edge binding.
