Description
Durable Cylinder Liner for Cummins KT38 / KT50
This 3022157 cylinder liner is used on Cummins KT38 and KT50 diesel engines, providing a stable and wear-resistant working surface for the piston assembly. It helps restore proper compression and sealing in worn engines, reduce oil consumption and exhaust smoke, and extend service life in demanding applications such as excavators, mining and industrial equipment.
High-Strength Material & Precision Machining
The liner is manufactured from high-quality alloy cast iron with controlled hardness and microstructure for heavy-duty diesel operation. Advanced machining and honing processes are applied to achieve a smooth cylinder surface, accurate roundness and correct bore size. This supports good lubrication, fast running-in and long-term wear resistance under high temperature and high load conditions.
Strict Quality Control
Each cylinder liner is produced under a controlled process and inspected before shipment. Dimensional checks, hardness tests and surface finish inspections are carried out to keep consistency between batches. Sample liners are installed and tested on Cummins KT38 / KT50 engines to verify sealing performance, heat transfer and running behavior during operation.
Stable Supply & Flexible Shipping
Regular stock and scheduled production support engine rebuilders, workshops and parts distributors who service Cummins KT38 and KT50 engines. Liners are packed with anti-rust protection and delivered in strong export cartons or wooden cases to avoid damage in transit. Worldwide shipment is available by TNT, DHL, FedEx, UPS, air freight or sea freight according to your requirements.
