1798/1100G2K 1400 mm 1100 mm 145 mm 1352 mm 1160 mm Frequently Asked Questions about 1798/1100G2K Crossed Roller Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 1798/1100G2K over a 1100 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
To match diverse operational dynamics, CHG Bearing supplies 1798/1100G2K with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
Absolutely. The CHG Bearing 1798/1100G2K Crossed Roller Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 1798/1100G2K, FAG 1798/1100G2K, NSK 1798/1100G2K. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
To safeguard CHG Bearing 1798/1100G2K 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.
