1797/3230G2Y3K1 4100 mm 3230 mm 240 mm 3820 mm 3380 mm Frequently Asked Questions about 1797/3230G2Y3K1 Crossed Roller Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the 1797/3230G2Y3K1 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.
Quality starts with raw material selection: CHG Bearing crafts 1797/3230G2Y3K1 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 1797/3230G2Y3K1. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
The Open Type engineered for 1797/3230G2Y3K1 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.
