Japan SMC cylinder bore size represents the size of the cylinder output force. Piston in the cylinder to make a smooth reciprocating sliding, the surface roughness of the surface of the cylinder barrel should reach Ra0.8um. Of the steel cylinder, the inner surface should be hard chromium plated to reduce friction and wear, and to prevent corrosion. In addition to cylinder material carbon steel tubing or high-strength aluminum alloy and brass. Stainless steel cylinder with a small tube. Cylinder with a magnetic switch or corrosion environment in the cylinder, the cylinder should use stainless steel, aluminum or brass and other materials.
Japanese SMC cylinder piston is under pressure in the parts. About two-chamber piston to prevent gas channeling each other, with the piston ring. Wear on the piston ring can improve the orientation of the cylinder, the piston ring to reduce wear, reduce friction. Long use of polyurethane wear ring, PTFE, synthetic resin, cloth and other materials. The width of the size of the piston ring and necessary to determine the length of the sliding part. Sliding part of the short, easy to cause early wear and tear and stuck. Material commonly used aluminum pistons and cast iron, a small cylinder made ​​of brass piston.
  Japanese SMC air cylinder piston rod is the most important force components. Typically use high-carbon steel, hard chrome plated surface, or use stainless steel to prevent corrosion and increase the wear resistance of seals.
