At Olsen Actuators, our range of electric roller screw linear actuators is specially designed in order to ensure our customers achieve maximum performance. Olsen Actuators’ roller screw linear actuators are a superior choice to those offered by our competitors, thanks to the use of precision ground satellite roller screws. Our precision ground satellite roller screws deliver a greater degree of durability, meaning that product life span is longer and higher forces can be achieved, all within a significantly more compact unit size. These specialised screws also offer additional benefits, including low maintenance and significantly reduced cost of ownership.

A roller screw actuator differs from a ball screw by replacing the recirculating balls with threaded rollers, which are then toothed at each end in order to fit with gear rings at the end of the nut unit. This nut also features a threaded design, and the result is that the rollers achieve an orbit around the nut, in which they also rotate continuously on their axis. The greater surface area contact of the roller screw means that a higher dynamic load capacity may be achieved, whilst the threading of the rollers means that such higher loads require less input torque.

Electric roller screw linear actuators are more than ten times more efficient than air cylinders and 4.4 times more efficient than hydraulic alternatives, whilst also removing the problem of challenging and time-consuming maintenance that is often the case with such equipment. By choosing a product from our range of electronic linear actuators, you will also be benefiting from the reduced risk of noise and contamination that is typically associated with the alternatives based on air cylinders and hydraulics.

Olsen Actuators’ range of electric roller screw linear actuators come in a flexible design, which means that they are an incredibly versatile option, that may be used successfully in a wide variety of applications and configurations. This flexible approach to design includes a selection of models with a choice of pitch and travel, as well as the option to purchase a custom model for your precise specification. Olsen Actuators roller screw linear actuator selection comes with universal mounting options, meaning that they are compatible with many different motors, such as third-party DC, stepper and servo motor types. Meanwhile, secure fitting for standard motors is assured, thanks to Olsen Actuators options for preconfigured parallel and inline motor coupling mounts.

Our product range of roller screw linear actuators is built to last, providing a long life of service with minimum maintenance required, and all for a low-cost investment. Furthermore, where the units are to be put to use in the harshest and most demanding environments, our roller screw linear actuator range comes protected, thanks to our anodised aluminium housing extrusion with IP65 sealed body options. In hazardous conditions, choosing one of our electronic linear actuators from the EL/ER series is advised, with such units providing an integral gearbox and servo motor, in order to deliver exceptional torque to size ratios.

All of our products in our roller screw linear actuator collection are easy to install quickly and set up and ready to use with minimal installation effort. They represent a simple replacement for hydraulics and pneumatics whilst offering the advantage of having a reduced footprint size yet with like-for-like capabilities when it comes to power.

No matter what your application, or the environment in which you need to operate, we can create your ideal solution at Olsen Actuators. Our product range of electronic linear actuators comes with a versatile choice of frame sizes, from 50mm up to 330mm, and with velocity ratings of up to 1.5m/sec. We offer electronic linear actuators with force Ratings ranging from 409N through to 370,000N, and travel distances of up to 2m, with 8m options at low speeds. Our electric roller screw linear actuators come with an impressive 3µm accuracy, and there are also zero backlash options available. We also offer a selection of specialised housing coating options and rods, so whatever your application, we can create your ideal product here at Olsen Actuators. That's why we are proud to be known as the actuator specialists.

High-performance planetary roller screw technology offers performance that is far superior to competing actuator technologies. Precision Ground Satellite roller screws provide long life and high force in a small package size and offer an advantage over Hydraulic Cylinders by offering longer life, lower maintenance and significantly reduced energy costs.
