About This Swing Motor

The M2X series covers Kawasaki swing motors for mid-size excavators such as Doosan DH225/DH258 and Samsung/R210 machines. Different spline counts and mounting hole patterns separate the sub-models — the spec table on each page lists exactly those dimensions.

The DH258(M2X150)12-hole is an OEM-standard aftermarket replacement built to the original mounting, spline and port specification. Direct fit for DH258-5/7 as listed in the catalog. 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.
