Piston rod cylinders

Piston rod cylinders

Cylinders with piston rods: as compact cylinders, short-stroke cylinders, flat cylinders, round cylinders, miniature cylinders, cartridge cylinders or stainless steel air cylinders

Specified types in accordance with the ATEX directive are suitable for explosive atmospheres or are made of corrosion-resistant stainless steel and therefore particularly easy to clean.

Rodless cylinders

Rodless cylinders

Compact linear actuators with or without guides: mechanically coupled cylinders with optimized mounting options for simple mounting and magnetically coupled cylinders for use as a pressure-tight and zero-leakage system.

Rotary actuators

Rotary actuators

Compact quarter turn actuators with minimum space requirements and adjustable swivel angle, also available as a twin piston rotary actuator

Specified types are suitable for potentially explosive atmospheres in accordance with the ATEX directive.

Tandem, high-force and multi-position cylinders

Tandem, high-force and multi-position cylinders

More thrust than conventional cylinders by connecting in series 2, 3 or 4 cylinders with the same piston diameter and the same stroke.

By connecting 2 to 5 cylinders in series with the same piston diameter and different stroke lengths, up to 6 positions can be approached. .

Pneumatic actuators

Piston rod cylinders

These are pneumatic actuators for carrying out linear movements. Energy applied to the piston is transmitted to the parts to be moved via a piston rod. Depending on the piston diameter, pushing forces of up to 50 kN at 6 bar are possible.

Rodless cylinders

Rodless linear actuators are pneumatic actuators in which the power is transmitted via a lateral connection to the piston. The required installation space is significantly smaller than with a comparable piston rod cylinder. The connection to the piston is either mechanical through a slot in the profile barrel or magnetically through a closed profile barrel.

Rotary actuators

Pneumatic rotary actuators from Festo enable rotary movements up to a swivel angle of 270°. Highest precision is just as characteristic as the high performance and variety of the actuators.

Multi-position actuators

Pneumatic multi-position actuators are available with two different functional principles. According to the first principle, multi-position actuators consist of two separate cylinders which are connected together by a kit and have piston rods that extend in the opposite direction. Depending on the control and stroke distribution, this cylinder type can therefore assume up to four positions. According to the second principle, multi stage pneumatic cylinders consist of two to five cylinders connected in series with different stroke lengths. With this cylinder type, only one piston rod is visible, which moves to different positions in one direction.

Guided cylinders

Pneumatic guided cylinders are very sturdy, heavy-duty, compact and precise.
Actuators with guide rods are attached to the yoke plate, which is thus secured against rotation and is consequently sturdy and resilient. Sliding drives are characterized by high precision and repetition accuracy.

Stopper cylinders

Pneumatic cylinders used for damped or undamped stopping of movements in machines or workpiece carriers on transport systems. On transport systems, stopper cylinders with cushioning can stop loads of up to approx. 800 kg.

Clamp cylinders

Clamp cylinders hold or clamp workpieces either directly with a pneumatically operated clamping element or via kinematics. The clamping element is swiveled out of the working area in the inactive status. Using kinematics, very high holding forces can be achieved with low energy consumption.

Bellows and diaphragm actuators

Bellows and diaphragm actuators form a class of their own in the world of pneumatics with special characteristics. For example, they have no stick-slip effect. They can be used as actuator or air spring elements in a wide range of applications.

Rotary indexing tables

Continuous rotary movements can be realized with pneumatic rotary indexing tables. Rotary indexing tables are used, for example, in assembly applications. A variable direction of rotation and freely selectable graduations allow a wide range of applications.

Cylinder/valve combinations

This is a unit consisting of a pneumatic actuator with integrated or attached valve for control. Installation of the pre-assembled unit is easy. There are fast switching times due to the short distance from the valve to the actuator.

Shock absorbers

Shock absorbers absorb the energy of a moving actuator. The movement of the drive piston is brought to a standstill by rubber elements and/or hydraulically. The relatively gentle stopping before the end position prevents a strong impact as well as springback and also protects the actuator and the machine parts from wear or irreparable damage.

Grippers

A gripper is a pneumatic or electric actuator and is used to hold, position and move a workpiece. A gripper represents the connection between the workpiece and the industrial robot.
