The Feed Modules from Rexroth are suitable for using in handling applications as vertical axes or actuators. The complete linear units reduce the necessary drive power due to the smaller dead weight being moved and can achieve extremely precise, infinitely variable positions.
The modules consist of a fixed aluminum main body, a profiled aluminum tube with eLINE Hybrid Technology and runner blocks and spindles of different pitches and sizes.
The spindle moves a profiled aluminum tube, the spindle sleeve into which two steel tracks are admitted. Two fixed runner blocks in the main body guide the spindle sleeve accurately and cushion high longitudinal and transverse torques. The quadratic main bodies with cross-sections of 50mm, 70 mm and 100 mm, rastered, cover strokes of up to 400 mm.
Another special feature is the quick and easy assembly using the easy-2-combine interface. This positive connection technology with centering rings saves laborious alignment. In addition, unlike in many conventional solutions, you are also spared specially manufactured adapters.
You can order the feed modules either with a flange or belt auxiliary transmission for mounting on motors, or ready assembled as complete axes. There is a wide range of servomotors or stepping motors with an absolute encoder or standard encode and an optional brake. Positioning the motor on the fixed main body makes the electrical connection easier for you.

The ELIMINATOR HDL™ replaces hydraulic and pneumatic linear actuators with an electromechanical linear actuator with an Optional Load Cell. This combines force measurement with heavy duty and precise linear motion. It provides a clean, simple, rugged, and economical capability to directly and continuously monitor axial force while simultaneously applying that force.
This ball screw actuator can measure force in both tensile and compressive modes. The heavy wall steel construction and high dynamic capacity components ensure longevity and durability for production processes. Bearing press, component insertion, and product testing, are typical applications where this would be useful. As an integral package, the ELIMINATOR HD™ with load cell is less expensive and much easier to align than traditional ball screw component systems. As a sealed assembly, it is far less susceptible to contamination and physical damage.

The new series of electromechanical actuators with ball screw from Rexroth enables high feed speeds even with heavy loads.
All important components come from Rexroth's service-proven range of standard products, including three different stepping and servo motors with various performance profiles.
The mechanism is based on the tried and tested rolling precision ball screw drives in all common combinations of diameter and pitch. Performance characteristics such as precision of positioning, axial load and speed can be optimized in accordance with the requirements of the individual application.
Using a screw drive rules out the stick-slip effect associated with other designs and increases the repeat accuracy of the overall system.
By using ideally-dimensioned inclined axial roller bearings, the load rating of the ball screw drive can be utilized to the maximum. There is an extensive range of possibilities to choose from in the drive configuration and the fastening elements.
The new components fully comply with protection class IP65, and thanks to the use of corrosion-resistant material are ideal for applications in packaging systems with frequent cleaning cycles. Similarly, the robust combination of power and speed promise substantial benefits in dosing and processing systems, in machine tools and woodworking machines, and in general automation.

The linear jacks high efficiencies ELVP integrate a screw into satellite rollers of Rollvis mark, animated by a servo engine Bruschless (assembly with reducer or directly coupled with the screw). They are conceived for applications to high frequencies of use, asking one long life of life under loads and/or speeds high. Electromechanical jacks ELVP are equipped with a screw with satellite rollers. Why? The screw with satellite rollers is similar to the ball screw with the difference close the elements of transfer of charge are threaded rollers. The principal advantage of the screw with satellite rollers it is that it has a great number of contact point to transfer the load. It results from it a load capacity up to 3 times higher than that from the ball screws and a lifespan up to 15 times higher, while preserving an output which can reach 90%
