SMC气缸是由缸筒、端盖、活塞、活塞杆和密封件组成，其内部结构如图所示：  SMC CM2气缸活塞上采用组合密封圈实现双向密封，杆侧端盖上设有密封圈和防尘圈，活塞要在缸筒内做平稳的往复滑动，缸筒内表面的表面粗糙度应达到Ra0.8um。对钢管缸筒，内表面还应镀硬铬，以减小摩擦阻力和磨损，以防止从活塞杆处向外漏气和防止外部灰尘混入缸内。杆侧端盖上设有导向套，以提高气缸的导向精度，承受活塞杆上少量的横向负载，减小活塞杆伸出时的下弯量，延长气缸使用寿命。导向套通常使用烧结含油合金、前倾铜铸件。端盖过去常用可锻铸铁，现在为减轻重量并防锈，常使用铝合金压铸，微型缸有使用黄铜材料的。SMC气缸原理图内径大小代表了气缸输出力的大小。并能防止锈蚀。缸筒材质除使用高碳钢管外，还是用高强度铝合金和黄铜。小型气缸有使用不锈钢管的。带磁性开关的气缸或在耐腐蚀环境中使用的气缸，缸筒应使用不锈钢、铝合金或黄铜等材质。活塞与活塞杆用压铆链接，不用螺母。端盖 端盖上设有进排气通口，有的还在端盖内设有缓冲机构。SMC cylinder is a cylinder, end caps, piston, piston rod and the sealing composition of their internal structure as shown: the SMC the CM2 piston combination seals bi-directional seal on the rod side of the end cap has a ring anddust ring, the piston in the cylinder, smooth reciprocating sliding, the surface roughness of the surface inside the cylinder should reach Ra0.8um. Steel pipe cylinder, the inner surface should be hard chrome plating to reduce friction and wear in order to prevent outward from the piston rod at the leak and prevent external dust mixed with the cylinder. On the rod side of the end cap has a guide sleeve in order to improve the orientation accuracy of the cylinder, and bear the piston rod on a small amount of lateral load, reducing the piston rod out when the next bend amount, extend cylinder life. The guide sleeve is usually sintered oil alloy, forward the bronze pieces. End caps in the past commonly used malleable iron, to reduce weight and rust-proof, and often use the aluminum die casting, micro-cylinder used brass materials. SMC cylinder principle of hole size represents the size of the cylinder output force. And to prevent corrosion. In addition to the use of high-carbon steel pipe, the cylinder material, or use of high strength aluminum alloy and brass. The small cylinder has the use of stainless steel pipe. Cylinder with a magnetic switch or cylinder used in the corrosion environment, the cylinder should be used in stainless steel, aluminum or brass and other materials. Piston and piston rod with Riveted links, not the nut. The end cap on the end cap with the intake and exhaust openings, and some still end cap equipped with a buffering mechanism.襄阳德而尼自动化设备有限公司专业销售日本SMC，SMC气动，SMC气缸，SMC接头，SMC电磁阀等，并具有价格优势，快速报价，询价！
