Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for 293/1250 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 293/1250 Spherical Roller Thrust Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 293/1250, FAG 293/1250, NSK 293/1250. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
The CHG Bearing 293/1250 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
To safeguard CHG Bearing 293/1250 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (1250 mm x 1474 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
