Swing secondary assemblies — the second-stage planetary carrier and gear set inside the swing reducer. Listed by machine fitment: DH55/225-7, E318/E320C, LG200/225, EX200-5, EC210/EC360, PC120-6/200-6/200-7/240-8, SK200-6/200-8, SY135, SH200, R210.
The E320C Swing Secondary Assembly 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.
It is the second-stage planetary assembly of the swing reduction gearbox — carrier, planet gears, pins and thrust washers as one unit. The stage-1 (primary) assembly is the first stage.
If the swing is weak and noisy, remove the gearbox and inspect both stages. Usually the stage nearest the failed bearing shows the wear. Send photos and we identify the stage.
Planet gears, pins, carriers and thrust washers are available separately for the popular frames — tell us the stage and machine model.
Send your part number, machine model or a nameplate photo — WhatsApp is fastest.
