Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing 1797/3230Y3 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.
When fitting 1797/3230Y3 over a 3230 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Standard batches of CHG Bearing 1797/3230Y3 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 1797/3230Y3 with a precision bore diameter (d) of 3230 mm, an outside diameter (D) of mm, and a nominal ring width (B) of 240 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.
