Piston

Engine components: bushings, pistons, bearings, and complete gaskets

Engine components including bushings, pistons, bearings, and complete gaskets are manufactured from alloy steel and high-strength aluminum to ensure durability under severe operating conditions. Bushing surfaces are hardened to 55–60 Rockwell C, and bearings are cold-rolled to 50 Rockwell C for enhanced wear resistance. Pistons are produced with dimensional tolerance below 0.01 millimeters and can withstand combustion pressures up to 120 bar. Gaskets are made from multilayer steel with copper and nickel coating to ensure complete sealing and prevent oil and coolant leakage.

The weight of each engine component set ranges from 3 to 25 kilograms depending on engine model, with installation performed using precision tools and standard bushings. Operating temperature ranges from minus 40 to plus 250 degrees Celsius, while gasket heat resistance reaches up to 300 degrees Celsius. Bearing lubrication is provided by standard engine oil at 5–7 bar operating pressure to ensure uniform operation and reduced wear. The estimated service life of this set under standard conditions exceeds 12000 hours.

Main Rotor Piston Finger 220

The main rotor piston finger 220 is made of hardened alloy steel with a wear-resistant coating, and its shaft diameter is 18 millimeters. The total length of the finger is 120 millimeters, with a distance from the axis to the connection center of 45 millimeters. The design of bearing grooves and internal lubrication channels reduces friction and increases component lifespan up to 5000 continuous operating hours. The axial load capacity of the finger is up to 2500 Newtons, and the instantaneous torque capacity is 180 Nm. The outer surface is chromium-coated for wear resistance and can withstand temperatures up to 300°C.

The finger shaft is dimensionally controlled with ±0.02 millimeter precision after CNC machining. Lubrication grooves are 2 millimeters in diameter and spaced 10 millimeters apart to ensure optimal oil flow. All internal rotor components, including bushings and support rings, undergo stress and vibration testing according to ISO 1940. The total weight of the finger is approximately 1.6 kilograms, and its bending strength under operating conditions is 1200 N/mm².

Pistons of the 200-220-6-7 Engine

The pistons of the industrial 200-220-6-7 engine are made of high-strength aluminum alloy, capable of withstanding temperatures up to 250°C and pressures up to 120 bar. The piston crown diameter ranges from 95 to 110 millimeters, and the overall piston height is approximately 85 millimeters. The crown design features internal cooling channels and precise grooves for installing compression and oil rings. Each piston weighs between 1.2 and 1.5 kilograms, and the outer surface is coated with hardened nitride to reduce wear and increase service life.

The connecting rod attached to the piston is made of alloy steel, capable of handling instantaneous torque up to 300 Nm. Piston rings include two compression rings and one oil ring, designed to withstand temperatures up to 300°C. The clearance between rings and piston grooves is precisely controlled at 0.02 millimeters to minimize leakage and maximize combustion efficiency. All pistons undergo CNC machining followed by balance testing and precise dimensional inspection.

95L Izumi Piston

The 95L Isumi piston is made from aluminum alloy with precise heat treatment to ensure tensile strength of 320 to 350 MPa and surface hardness of 180 to 220 HB. Its outer diameter is 95 mm, with a stroke length between 120 and 150 mm. It is designed to withstand hydraulic pressures up to 250 bar and operating temperatures of 120 degrees Celsius. The friction surface is coated with wear- and corrosion-resistant material to ensure long-lasting performance under severe operating conditions.

The piston rings are manufactured with dimensional accuracy of ±0.02 mm to minimize oil leakage and hydraulic pressure loss. The piston weighs 2.8 to 3.2 kg and can handle axial torque up to 350 Nm. Its design reduces vibration and uneven pressure, providing smooth operation and extending the hydraulic system’s service life.
