Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 1797/2600G2 with a precision bore diameter (d) of 2600 mm, an outside diameter (D) of mm, and a nominal ring width (B) of 200 mm. This configuration yields an effective cross-sectional wall thickness of 0 mm and an envelope ratio (D/d) of 0, delivering compact rigidity for OEM machinery housings.
Standard batches of CHG Bearing 1797/2600G2 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
Built for demanding industrial environments, the 1797/2600G2 Crossed Roller Slewing Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
In its sealed configuration (Open Type), CHG Bearing pre-charges 1797/2600G2 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
