As its name suggests the new Framo LiMax from R. A. Rodriguez is a linear actuator with a maximum force rating. Its modular design uses an in-line layout of motor, planetary gearing and lead or ballscrew drive to achieve a high force rating in relation to the diameter of the body. It is also available with a wide range of options enabling the actuator to be tailored to the exact requirements of the application. These include a choice of motors, encoders and other customised adaptations including stroke lengths. Various types of mounting and end connections may also be specified.

As standard, LiMax has an all-stainless steel body, piston and end fittings. These qualities, coupled with an IP65 rating, allow it to provide trouble-free actuation in exposed locations and corrosive environments. The designers of this product have also paid particular attention to its aesthetics. Given its all-weather suitability it is therefore ideal for applications such as climate control systems on the facades of buildings.

Simple to fit and operate with a long life expectancy and minimal maintenance needs, LiMax is easily integrated into existing control systems. In-built stroke limit switches are fully adjustable allowing on-site fine-tuning to suit the application. It is reliable in extreme heat and in the presence of dust and moisture so its scope of use is wide. In addition to building engineering, LiMax is already proving popular for use in telecommunications and in the hygiene conscious food and pharmaceutical industries.

LiMax is available in two basic body size diameters of 60mm and 80mm with standard stroke lengths from 200 to 800mm; shorter stroke lengths are available on request. The units provide a stroke force of 5,200N with stroke speeds from 3 to 360mm/s.
