Types Of Cylinders
Mar 06, 2025| Here is a detailed classification of the main types of cylinders and their characteristics:
1. Pencil-shaped cylinder (mini cylinder)
Features: compact structure, low price, suitable for high-frequency use, saving installation space. Materials include stainless steel and aluminum alloy, commonly used in electronics, medical, packaging machinery and other industries.
Notes: It is necessary to use a magnetic switch mounting bracket and connect the moving parts through a floating joint to prevent jamming.
2. Thin cylinder
Features: light weight, small space occupation, square cylinder body, can be directly installed on the fixture or equipment. Need to be used with guide elements.
3. Free installation cylinder
Features: short stroke, rectangular cylinder body, support fixing from four directions of the body, flexible installation method.
4. Double-axis cylinder
Features: It is composed of two single-rod thin cylinders in parallel, with guidance and lateral load resistance, suitable for occasions requiring large output.
5. Guide rod cylinder
Features: It has its own guiding function and is divided into linear bearing type (low friction occasions) and copper sleeve type (high load occasions), suitable for blocking, feeding and other scenes.
6. Slide cylinder
Features: It adopts cross ball guide rail for guidance, with low friction, smooth movement and high guiding accuracy, but the price is relatively expensive.
7. Rodless cylinder
Features: It has no rigid piston rod, saves space and is suitable for small cylinder diameter and long stroke occasions. It is divided into two types: mechanical coupling and magnetic coupling.
8. Air claw (pneumatic gripper)
Features: It can realize two-way grasping, high repeatability and constant grasping torque. Types include parallel air claw, swing air claw, etc.
9. Swing cylinder
Features: It is divided into gear rack type and vane type, which is used for operations such as rotating and turning objects.
10. Rotary down-pressing cylinder
Features: It is suitable for compact space structure to realize rotary pressing action.
