3-943G2 3850 mm 3322 mm 200 mm 3720 mm 3420 mm Frequently Asked Questions about 3-943G2 Crossed Roller Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 3-943G2 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 3322 mm) and steep thermal gradients between inner and outer rings.
Engineered according to international ISO boundary plans, CHG Bearing supplies 3-943G2 with a precision bore diameter (d) of 3322 mm, an outside diameter (D) of 3850 mm, and a nominal ring width (B) of 200 mm. This configuration yields an effective cross-sectional wall thickness of 264.0 mm and an envelope ratio (D/d) of 1.16, delivering compact rigidity for OEM machinery housings.
Beyond standard alloy steel, CHG Bearing can customize the 3-943G2 Crossed Roller Slewing Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
The Open Type engineered for 3-943G2 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.
