The IMA-S is the integration of an electric actuator cylinder made of stainless steel and a servo motor in a common housing. Tolomatic addresses applications in food technology and the beverage industry with the hygienic stainless steel electric cylinder IMA-S. The IP69K hygienic design features a 316 stainless steel construction and hygienic mounting and cable handles that allow open machine design and effective cleaning in the field. Even with the IP69K design, special attention has been paid to the hygiene requirements, so that bacterial growth and corrosion are prevented even with aggressive cleaning. The patented relubrication system and the FDA-approved food-grade grease used also meet the requirements of the food industry and guarantee an extremely long service life.
As with the standard IMA electric cylinders, both ball screws and roller screws are available for the IMA-S hygienic stainless steel electric cylinders with IP69K. Optionally, an anti-rotation device can be integrated (IMA-SA), which makes external guidance superfluous. The IMA-S stainless steel electric cylinders offer forces up to 11kN and can also be used for applications with high duty cycles.
The integrated standard servo motors are 8-pole and are available in two overall lengths and winding variants each for 230V ac or 400V ac / 480V ac; special windings e.g. for 24V dc, 48V dc are possible; resolvers, EnDAT 2.2, Hiperface and Hiperface DSL and others can be implemented as feedback and brakes are also available. Various connector options and pin assignments ensure compatibility with all common controllers, especially of course Copley and Kollmorgen.
IMA-S stainless steel electric cylinders are designed for applications such as cutting cheese or sausage, guiding, sorting, distributing food on conveyor belts or filling systems and pumping and dosing applications.

The RSA/GSA leadscrew actuators are linear electric actuators (electric cylinders), available in two versions for the low to medium (RSA-ST) and the higher (RSA-HT) force range, optionally with a linear guide (GSA). The RSA/GSA electric cylinders are designed for industrial applications with high demands on load capacity and service life; for this purpose, generously dimensioned bearings, internal buffer end stops and a robust aluminum housing are standard features of the RSA/GSA spindle actuators. The RSA-HT electric linear actuators (electric cylinders) are additionally equipped with a patented relubrication system, which allows the leadscrew to be relubricated easily and conveniently without dismantling the actuator, thus significantly extending the service life of the leadscrew.
The installation of additional sensors is already prepared and there is a wide range of options for installation.
With the GSA series, the RSA-ST linear leadscrew actuators are supplemented by linear guide rods with up to 914mm stroke, which allow the absorption of higher side loads.
Due to the flexible motor mounting of the RSA/GSA electric actuators, servo motors and stepper motors of all voltage classes 24V dc, 48V dc, 230V ac and 400V ac can be used and all common operating voltages can be realized. Also all encoders and options regarding brakes, connectors etc. can be considered, so that compatibility with all common controllers can be achieved.
Applications of these electric linear actuators (electric cylinders) can be found in the replacement of pneumatic actuators with the advantage of free programmability and exact controllability - changes of format settings are possible at the push of a button without long production interruptions. Typical applications are presses, injection moulding machines, valve actuators and many more.
The general characteristics of the electric linear actuators (electric cylinders) RSA-ST and RSA-HT:
The RSX linear electric actuators (electric cylinders) are planetary roller screw type linear actuators and offer extremely high forces up to 133kN; they are designed as electric replacements for hydraulic linear actuators. A special version for presses with up to 178kN thrust is also available. The advantages are obvious: electric linear actuators are more efficient, more flexible, quieter and do not cause dirt through leaking oil lines. These RSX roller screw linear actuators are designed and tested for long life and can be used under extreme conditions and in cold weather.
Due to the flexible motor mounting the RSX electric cylinders can be equipped with servo motors of the voltage classes 230V ac and 400V ac and all encoders and options regarding brakes, connectors etc. can be considered, so that compatibility with all common controllers can be achieved. The possibility of fitting food-grade servo motors makes it an ideal combination for applications in the food sector with, for example, special cleaning requirements (high-pressure cleaning, washdown, chemical resistance, etc.).
The main applications for these electric actuators (electric cylinders) can be found in motion simulators, injection moulding machines, presses, bending machines and punches, woodworking machines and food processing technology.

The MXE rodless linear leadscrew actuators of our partner Tolomatic were developed to be used with moderate to high load capacity and guidance. Furthermore, they are characterized by long service life and load capacity. They are available in 2 different versions: fixed bearing MXE-S, or with profile rail MXE-P. Both types are available in 6 different sizes to guarantee a high flexibility.
The MXE-S rodless linear leadscrew actuators are designed for low to medium load capacity. The MXE-S rodless linear leadscrew tables have a robust plain bearing, which is insensitive to dust and dirt and can be replaced on site. They also have a lightweight aluminium housing.
The MXE-P rodless linear leadscrew actuators are designed for moderate to high load carrying capacity. The MXE-P rodless linear leadscrew tables have an even longer service life due to the precision recirculating ball bearing guides and their reduced friction. Furthermore, integrated magnets make sensor devices easier to install.
Due to the flexible motor flange of the MXE linear screw actuators all common servo motors and stepper motors can be mounted. Thus, our motor selection provides motors for all operating voltages, e.g. 24V dc, 48V dc, 230V ac and 400V ac. Also all feedback options like resolver, digital AquadB encoder or absolute encoder like EnDAT, Hiperface DSL, BiSS etc. and options regarding brakes, connectors etc. can be considered, so that compatibility with all common controllers can be achieved.
The main applications for these rodless linear leadscrew tables are found in packaging technology, in sorting systems, in printing and scanning technology and in automated production systems.
