Swing gear rings (internal ring gears), swing bearings and slewing rings for the mainstream excavator families — ZT series swing rings, DH, PC, SK, ZAX, E-series and LG fitments. These are the hardened internal-gear and bearing components that carry the upper structure, plus the planetary carriers and gear sets used in swing and travel reductions.
The SK200-8 is an OEM-standard aftermarket replacement built to the original mounting, spline and port specification. Bolt-on installation — no machining or adaptation required.
Every unit is inspected and pressure-checked before dispatch and ships with a test report. Stock models leave within 48 hours; non-stock units are typically ready in 5–15 days. Sea, air and express shipping are available worldwide, and our team answers quote requests within 12 hours — usually much faster on WhatsApp.
Count the internal teeth and measure the outside diameter and the bolt-hole pitch circle. Send both numbers plus the machine model on WhatsApp and we match the ring.
They are separate parts — this catalog lists both. Tell us which one failed; usually the bearing race wears while the internal ring gear stays serviceable.
Yes — swing pinions, planet gears, carriers and sun shafts are available for the popular families. Send the gearbox number.
Send your part number, machine model or a nameplate photo — WhatsApp is fastest.
