1798/1100G2K1 1400 mm 1100 mm 140 mm 1352 mm 1160 mm Frequently Asked Questions about 1798/1100G2K1 Crossed Roller Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 1798/1100G2K1 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.
Model 1798/1100G2K1 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 1100 mm) and steep thermal gradients between inner and outer rings.
To extend the trouble-free lifespan of CHG Bearing 1798/1100G2K1, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
Sourcing 1798/1100G2K1 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Crossed Roller Slewing Bearings.
