main pin of the 220 rotary piston rotor , Iran

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.You can order and buy main pin of the 220 rotary piston rotor from Iran by contacting us through whatsaap and email.
