smc pneumatic gripper, pivot open/close type

smc pneumatic grippers are actuators that use compressed air as power to clamp or grasp workpieces. This technology originated in Japan and was later widely adopted by domestic automation companies. Based on style, they are typically classified into Y-type fingers and parallel fingers. Bore diameters include 16mm, 20mm, 25mm, 32mm, and 40MM. Their main function is to replace manual gripping tasks, effectively improving production efficiency and operational safety. The SMC pneumatic finger series is one of the commonly used pneumatic gripper devices in the industrial sector.

smc pneumatic grippers, also known as smc swing cylinders, are specialized fixtures in the pneumatic industry. Common types include smc parallel grippers: driven by two pistons. Each piston connects to the pneumatic fingers via a roller and a double crank, forming a special drive unit. Thus, the pneumatic fingers always move axially centered; each finger cannot move independently. If the fingers move in reverse, the previously pressurized piston exhausts while the other becomes pressurized. smc parallel grippers are driven by a single piston, with the shaft driving the crank; each of the two jaw plates has a corresponding crank slot. To reduce friction, the connection between the jaw plates and the body uses a ball slide rail structure. smc swing grippers (Y-type grippers): The piston rod of the smc swing gripper has an annular groove. Since the finger trunnions connect to this annular groove, the fingers can move simultaneously and self-center, ensuring constant gripping torque. smc rotary grippers: The action of rotary grippers works on the principle of rack and pinion engagement. The piston is fixed to a shaft that can move up and down. The end of the shaft has three ring slots that engage with two drive wheels. Thus, the pneumatic fingers can move simultaneously and self-center, and the rack and pinion principle ensures constant gripping force. smc three-point grippers: The piston of the smc three-point gripper has an annular groove. Each crank connects to a pneumatic finger, and piston motion directly drives the three cranks, thereby controlling the simultaneous opening and closing of the three fingers.
