Short-stroke linear actuator instead of pneumatic cylinders
The new short-stroke linear actuator (KuLi) from Ketterer Antriebe and halstrup-walcher is characterized by high dynamics and a large stroke in a compact size. Thanks to the integrated electronics, the drive is easier to control than pneumatic cylinders.
The new electrically operated linear actuator is extremely compact and highly dynamic. With a length of 82 mm, the stroke is 40 mm, which can be covered in less than 100 milliseconds. The standard version of the KuLi offers thrust forces of up to 300 N. 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 KuLi short-stroke linear actuator does not require any sealing or throttling technology 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. A company achieves the greatest savings with the use of short-stroke linear drives if it dispenses with the entire compressed air system as a result of the conversion. The drive from Ketterer and halstrup-walcher is maintenance-free and there is no need for expensive servicing as with pneumatic cylinders.
The linear actuator is also superior to pneumatic alternatives in terms of handling. The speed and force can be adjusted to suit the application requirements. The KuLi can be controlled with a computer via a parameterization adapter with USB interface. The focus here is on simple handling. The software has a particularly user-friendly interface that can be operated without programming knowledge. Another advantage of the KuLi is the new technology in which the rotational movement of the motor is converted into a linear movement by a smooth shaft. This enables very good sealing of the shaft against the motor.
