Rolaram® is an electro-mechanical linear actuator, which consists of either a SpiraconTM planetary roller screw or a ball screw, driven by an electric motor, through a reduction gearbox. The lead screw converts rotary motion to linear movement. As the screw rotates, the nut extends and retracts the ram, which is attached to the load. As electric rod-style actuators overtake fluid power in a variety of high-force applications, it is important to understand how different screw

Ball screws and planetary roller screws can convert the rotational motion of an electric actuator into linear motion. Planetary roller screws are characterized by higher load ratings and better tolerance against shock loading because the number of contact points between the screw shaft and nut is significantly higher than ball screws.

Rolaram® is an electro-mechanical linear actuator, which consists of either a SpiraconTM planetary roller screw or a ball screw, driven by an electric motor, through a reduction gearbox. The lead screw converts rotary motion to linear movement. As the screw rotates, the nut extends and retracts the ram, which is attached to the load. In addition, the size and configuration of a roller screw, conventional or inverted, can be fine-tuned so the actuator will meet all the performance requirements of the application in a smaller envelope. An actuator with roller screws will also consistently exceed the dynamic load capability and lifetime of a much larger ball screw one. Roller screw actuators offer several advantages

Return to table of contents EL120 explosion-proof actuators meet ATEX requirements for use in potentially explosive atmospheres and are in conformity with the EU ATEX Directive 2014/34/EU. Additionally, these actuators are rated for Class 1, Division 1, Groups B, C, D, and T4 hazardous environments. The EL Series integrates a highly efficient planetary roller screw mechanism Types of Screw-Driven Actuators There are several types of screw mechanisms used in electric linear actuators. The main categories are lead screws, ball screws, and roller screws – each with distinct designs and performance characteristics. All of these are based on the same fundamental principle of a nut traveling along a threaded screw, but they differ in how the

r exceed the load ratings of the roller screws. A traditional bearing pack that matches the roller screw’s capabilities is much too large to fit into the limited physi-cal space of the actuator body, so the mpetition’s whole actuator must be de-rated. Every component in a CPD actuator is uniquely designed to handle the CMC Patented Tolomatic manufactures roller screws for individual sale and utilization in their linear electric actuators. This video compares ball screw and roller screw technologies, and describes the

Exlar integrated motor actuators integrate all the advantages of roller screw and T-LAM stator technologies to create powerful and robust solutions with long life. The specially designed roller screw mechanism efficiently converts electric Selection and functional parameters of roller screw had been evaluated screw actuators offer several advantages to optimize the linear actuator based on roller screw. Tesla’s humanoid robot Optimus uses 1:14 planetary roller screws. At Tesla AI Day on October 1, the humanoid Optimus prototype used planetary roller screws and harmonic reducers as an optional linear joint solution. According to the rendering on

We have exclusive supply agreements with Exlar servo electric roller screw linear actuators, ALT precision ground roller screws and roller bearings, ANCA high force Linear Actuators Exlar FT Series force tube actuators use a planetary roller screw mounted inside components provide a telescoping tube mechanism. The follower is attached to the moveable force tube, which then extends and retracts as the screw rotates. An external motor (supplied by Exlar or the customer) provides the rotational force. In the world of linear motion systems, both roller screw actuators and ball screws are widely used to convert rotary motion into linear motion. Although their uses are similar, they have different features, benefits, and applications.

But roller screws can turn considerably faster and cycle more frequently than both acme and ball screws, making them an ideal fit for demanding, continuous-duty applications. The working principle of the planetary roller screw is: the matching motor drives the screw to rotate, and through the meshing rollers, the rotational motion of the motor is converted into the linear reciprocating motion of the nut. The planetary roller screw combines spiral motion and planetary motion, which is very suitable for comprehensive Situations with higher performance
