Finger cylinders are compact pneumatic actuators designed for precise linear motion in automation and industrial applications. They feature a slim, finger-like profile, making them ideal for confined spaces. Common types include single-acting and double-acting cylinders, with customizable stroke lengths and mounting options. Key applications include part positioning, clamping, and material handling in assembly lines, robotics, and machinery. Popular models may include SMC MJFL, Festoon MQF, and Bosch Rexroth CRDNG series. These cylinders offer high durability, corrosion resistance, and compatibility with various pneumatic systems.
