New Linear Actuators From SKF are Versatile and Robust

The latest Jaeger FD-series linear actuators from SKF combine near-silent operation with robust construction, economy and versatility, making them particularly suited to medical and healthcare applications, such as reclining and massage chairs, as well as for use in industrial automation, safety door control and the powered operation of windows and skylights. FD-series actuators are available in two versions. The FD A1 has a maximum push force of 6kN and a maximum pull force of 4kN, with an operating speed of 2.6mm/sec to 4.2mm/sec depending on load. For the FD A2 models, the corresponding figures are 3kN push, 2kN pull, with operating speeds from 6.2mm/sec to 8.2mm/sec. Both types are offered in models with stroke lengths ranging from 50mm to 300mm. All FD-series actuators are supplied complete with integral limit switches, making them easy to integrate with control systems of all types. They are offered with a choice of Hall-effect or reed-switch position encoders which, according to the type selected, provide from 0.625 to 10 pulses per millimetre of actuator movement. Part of a complete system which includes control boxes, convenient hand-held operating units and a wide range of accessories, FD-series actuators operate from a 24V DC supply, ensuring complete electrical safety even in difficult operating environments. They have an IP52 ingress protection rating and, to help maximise their versatility, feature a rear clevis which can be turned through a full 90º. Ideal for use with Jaeger FD-series actuators from SKF are CB200 control boxes which can, if required, be mounted directly on the actuator. These control boxes are available with integrated overload protection and an anti-pinching function, and are compatible with robust HS-series one- and two-button handsets.
