Bellows actuator EB -V- New EB-80 Bellows actuator EB Key features Key features Bellows actuators function both as driving and pneumatic spring com ponents. Bellows actuators function as a driving component by providing supply and exhaust functions. As the stroke increases, the force generated is reduced in relation to the EB-80 EB-145 … 385 1 1 6 2 2 3 4 4 Prerequisites for using a bellows actuator Space required hmin hmax Combined installation de Lateral offset The max. lateral offset must not be exceeded. When using two or more bellows actuators, the necessary mounting plates must be inserted between the cylinders to prevent a lateral break out. Tilted installation smax Minimum height The max. tilt angle á must not be exceeded to ensure that the bellows walls cannot touch. Maximum height The bellows actuator must not fall below a min. height, otherwise it will be damaged. 2 Pneumatic connection Mounting thread Port plate, on top Bellows Port plate, underneath Belt ring 5 5 Observe the installation space to ensure the bellows actuator does not come into contact with other machine parts during expansion. 1 2 3 4 5 6 bellows. There are no sealing compon ents and no moving mechanical parts. Bellows actuators are single-acting drives that do not require spring returns, as the reset is achieved by the application of external force. hmax 3 contractional force of the bellows. When bellows actuators are supplied with permanent pressure, they act as a cushioning component. The simple design consists of two metal port plates with an attached rubber hmin Suitable for use in harsh, dusty ambient conditions Can be used under water Sturdy design Large forces range from 1 … 50 KN Low installation height No stick-slip effect Maintenance-free The bellows actuator must not exceed a max. height, otherwise it will be damaged. è Internet: www.festo.com/catalogue/...
