About This Swing Reducer

The swing reducer (swing gearbox) is a two-stage planetary reduction mounted between the swing motor and the swing bearing pinion. Speed and torque matching are factory-calibrated for each machine family — high efficiency, low noise.

The LG200180 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.
