Cylinder

Category:

Unlike non-standard oil cylinders, cylindrical metal components guide the piston in a straight reciprocating motion within the cylinder. Air is converted into mechanical energy through expansion within the engine cylinder, and gas is compressed by the piston in the compressor cylinder, thereby increasing pressure. The cavity of the piston is placed on the cylinder block of the internal combustion engine. SMC and CM2 cylinder pistons use a combination sealing ring to achieve bidirectional sealing, and the piston is connected to the piston rod by press riveting, eliminating the need for nuts. The cylinder end cap is equipped with intake and exhaust ports, and some end caps also have a buffering mechanism. The rod side end cap is fitted with a sealing ring and a dust seal to prevent air leakage from the piston rod and to keep dust from entering the cylinder from the outside. A guide sleeve is installed on the piston rod side cover to improve the guiding accuracy of the cylinder, allowing the piston rod to bear a small amount of lateral load, reducing downward bending when the piston rod is extended, and extending the service life of the cylinder. The guide sleeve is usually made of sintered oil-containing alloys and forward-leaning copper castings. In the past, ductile cast iron was commonly used for end caps. To reduce weight and prevent rust, aluminum alloy die-castings are often used, while miniature cylinders are made of brass.
