Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for 1798/1100G2 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.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 1798/1100G2, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 1798/1100G2 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
To safeguard CHG Bearing 1798/1100G2 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (1100 mm x 1400 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
