Liner kit , Iran
The piston bushing is a critical mechanical component in internal combustion and diesel engines, reducing friction and providing lubrication between the connecting rod and crankshaft. Internal diameter typically ranges from 18 to 120 mm, with lengths of 20–80 mm, manufactured with precision tolerances of 0.01–0.02 mm. Bushings are made of alloy steel, brass, or copper with nickel-bronze or tin coating, providing surface hardness of 180–250 HB and tensile strength of 400–600 MPa. Internal oil holes ensure continuous lubrication and minimize wear.
Structurally, the piston bushing consists of an inner shaft, cylindrical body, and oil channels. Surface hardening and precise machining increase service life up to 50,000 hours in industrial engines and 200,000 km in light vehicles. Proper balancing reduces vibration and improves power transmission to the crankshaft. This design ensures smooth operation, high durability, and optimized fuel efficiency in diesel and gasoline engines.You can order and buy Liner kit from Iran by contacting us through whatsaap and email.

Signs of Wear and Failure in Piston Bushings in iran
The piston bushing is a key engine component, and its wear can reduce performance and cause serious engine damage. One main sign is increased oil consumption due to oil leakage between the piston and bushing. Unusual knocking or tapping sounds at high RPM indicate wear or bushing enlargement. Reduced engine power and increased exhaust smoke occur due to lower compression in the combustion chamber. Excessive heat, deformation, or grooves on the internal surface are also signs of mechanical failure. Regular inspection and timely replacement prevent damage to the cylinder and piston.
