Product Description

Component Overview: 9112188 Slewing Ring

The 9112188 (Deere AT201167) slewing ring is a heavy-duty structural upgrade designed specifically for 30-ton class carriers. Engineered to eliminate upper-structure wobble and gear grinding, this assembly provides perfect rotational stability for high-capacity trenching and mass excavation.

Engineering Specifications & Benefits

Dimensional Accuracy: Manufactured to exact OEM blueprints to ensure flawless alignment with your existing swing motor pinion gear.
Severe-Duty Hardening: Deep-induction hardened raceways designed to handle the catastrophic axial loads of 30-ton earthmoving.
Advanced Sealing System: Multi-lip, industrial-grade environmental seals lock in lithium grease and block out abrasive quarry dust.
Zero-Modification Install: Identical flange thickness and mounting bolt patterns eliminate the need for custom fabrication or shop adjustments.

Mechanic's Tech Note:Always verify your excavator's specific generation (e.g., Dash-2 vs. Dash-3) before installation. This slewing ring provides an exact 1:1 match for the models listed above, ensuring safe and reliable 360-degree rotation.
