Linear drive
Replacement for pneumatic cylinders
A new short-stroke linear actuator from Ketterer Antriebe and Halstrup-Walcher, which has now been launched on the market, is said to be much easier to control than pneumatic cylinders.
The new electrically operated linear actuator is extremely compact and highly dynamic. With a length of 82 millimetres, the stroke is 40 millimetres, which can be covered in less than 100 milliseconds. The standard version of the KuLi offers thrust forces of up to 300 newtons. Depending on the task, the stroke speed, stroke force, stroke length and mechanical connection can be selected to suit the application.
The drive is particularly suitable for use in automation and conveyor technology as well as in special machine construction, where pneumatic cylinders have been widely used to date. Unlike these, the short-stroke linear actuator does not require any sealing or throttling technology in order to achieve uniform piston speeds. In addition, all ancillary components for pneumatic cylinders such as hoses, valves, compressed air tanks and silencers are no longer required. The short-stroke linear actuator is therefore significantly more cost-effective. dsc
