The MAK M20 Cylinder Liner is a spare part for the MaK M20 series long-stroke marine diesel engines that was carefully designed and manufactured. With a 200 mm bore diameter and manufacturing that meets OEM standards, this cylinder liner guarantees a perfect fit and effective sealing within the engine block for long-term high-performance use.
The MaK M20 series, which came out in the 1990s, was a big step forward in long-stroke engine technology. This cylinder liner is made to the precise standards of the original design. It works with all inline designs (6M20, 8M20, and 9M20) that are used for marine propulsion and power generation on board.
With an integrated anti-wear ring, the MAK M20 cylinder liner gives parts a much longer life and lower wear rates, which lowers total maintenance costs and engine downtime.

Marine Applications:
- Commercial Cargo Vessels: These include bulk carriers, container feeds, and other cargo ships with M20 main engines.
- Passenger ferries and cruise ships need power systems that are reliable, have low emissions, and follow SOLAS rules.
- Support boats Offshore (OSVs): These are platform supply boats and anchor handling tugs with MaK M20 engines.
- Tugboats and Workboats: Heavy-duty port and ocean-going tugs need engines that work continuously and reliably.
- Marine diesel generating sets are power plants that are installed on ships and can produce between 1,224 and 2,160 kVA using 6M20C, 8M20C, or 9M20C configurations.
