Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing 1797/2600G Crossed Roller Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 1797/2600G, FAG 1797/2600G, NSK 1797/2600G. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
The CHG Bearing 1797/2600G 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.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 1797/2600G, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Model 1797/2600G 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 2600 mm) and steep thermal gradients between inner and outer rings.
