The swing ring is one of the most structurally critical components on your Kato excavator — and one of the most costly to replace if it fails suddenly. We supply premium-grade, induction-hardened replacement swing rings (slewing rings) engineered precisely for the Kato HD series lineup.
Why Choose Our Kato Replacement Swing Rings?
- Deep Induction-Hardened Teeth: Gear teeth undergo precise thermal tempering to optimise hardness depth — minimising tooth pitting and preventing premature shearing under maximum slewing acceleration.
- High-Load Capacity Raceways: Built from premium forged alloy steel with precision-ground internal tracks, distributing high-tonnage shifting loads evenly across the internal roller elements.
- Premium Dust and Moisture Seals: Rugged multi-lip rubber seals designed to retain heavy grease while excluding abrasive rock dust, grit, and moisture from the bearing track.
- Exact Bolt Hole Alignment: Machined strictly to OEM dimensional tolerances for a perfect torque-spec installation on both the lower cab body and upper frame.
Whether you're overhauling a compact utility machine or a large production excavator, we have the heavy-duty slewing ring replacement you need.
