Piston

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

Engine components including bushings, pistons, bearings, and complete gaskets are made of alloy steel and cast aluminum with heat treatment and surface hardening. Piston diameters range from 70 to 150 millimeters with a stroke of 60 to 180 millimeters, designed for operating temperatures up to 250°C and combustion pressures up to 100 bar. Bearings are designed for dynamic loads of 5 to 50 tons and lubricated with 10W-40 engine oil. Gaskets are made of copper or steel with nickel coating to prevent oil and water leakage up to 10 bar.

Bushings and pistons are manufactured with dimensional accuracy of 0.01 millimeters and inspected using non-destructive testing including ultrasonic and dye penetrant methods. Piston surfaces are coated with nickel-phosphorus or graphite to reduce friction and extend service life up to 8,000 hours. Assembly follows ISO 9001 and DIN 17005 standards, ensuring reliable piston and bearing performance under high temperature and pressure conditions.

pistons for engine 200-220-6-7

The pistons for engine 200-220-6-7 are made of high-silicon aluminum alloy Al-Si 12% to ensure wear resistance against the cylinder and operating temperatures up to 350°C. Piston diameters range from 95 to 110 mm and piston stroke length from 100 to 120 mm. The piston surface is anodized and T6 heat-treated, while piston rings are coated with chrome-molybdenum steel to withstand combustion pressures up to 180 bar.

Connecting rods and piston pins are made of hardened steel with a diameter of 25 mm, supporting radial loads up to 50 kN. Internal oil channels with 3 mm diameter ensure uniform lubrication and reduce friction between piston and cylinder. Pressure and thermal testing according to ISO 26429 guarantees a service life exceeding 10,000 hours in heavy-duty industrial and diesel engine conditions.

main pin of the 220 rotary piston rotor

The main pin of the 220 rotary piston rotor is made from alloy steel with a surface hardness of 58-62 HRC, ensuring wear resistance and hydraulic pressure tolerance up to 350 bar. The pin shaft has a diameter of 30 mm, an effective length of 120 mm, and weighs approximately 1.5 kg. Oil grooves are machined with 0.05 mm precision to optimize piston lubrication and reduce friction at speeds ranging from 50 to 2000 rpm.

The pin surface is heat-treated and hard-chrome coated, with mechanical fatigue and pressure testing up to 10,000 cycles. Installation uses grade 10.9 stainless steel pins, with play between rotor and pin less than 0.1 mm. This design ensures a service life exceeding 8 years under heavy industrial and hydraulic conditions and full compatibility with OEM 220 rotary piston components.

95L Isumi piston

The 95L Isumi piston is made from forged aluminum alloy with a surface hardness of 120-140 HB, ensuring resistance to cylinder pressure up to 180 bar and operating temperatures up to 250°C. The piston diameter is 95 mm, height 95 mm, and approximate weight 1.8 kg. Ring grooves are CNC-machined with 1.5 mm spacing to minimize gas and oil leakage and maximize power transfer efficiency.

The piston’s exterior is anodized and reinforced with MoS2 or DLC anti-wear coating to reduce friction with the cylinder wall. A 25 mm diameter steel gudgeon pin with 900 MPa tensile strength connects the piston to the connecting rod. Hydraulic pressure and movement cycle testing up to 1 million cycles ensure a service life exceeding 8 years in harsh industrial and environmental conditions.
