ServoBeltâ„¢ Linear Actuators Now Feature Molded Belt Tray, Improving Assembly and Serviceability
Bell-Everman announces that its latest generation of ServoBelt™ Linear actuators features a design enhancement that simplifies the assembly and installation of long-travel motion systems including gantry and linear robots. The new design, which involves the lower static toothed belt, also strengthens ServoBelt’s ability to non-destructively withstand high-force events, such as carriage crashes.
Bell-Everman announces that its latest generation of ServoBeltâ„¢ Linear actuators features a design enhancement that simplifies the assembly and installation of long-travel motion systems including gantry and linear robots. The new design, which involves the lower static toothed belt, also strengthens ServoBelt's ability to non-destructively withstand high-force events, such as carriage crashes.
In earlier designs, the belt adhered to its aluminum carrier using 3M's VHB adhesive tape. While strong, the VHB did complicate the assembly and installation process, requiring integrators to accurately apply the adhesive tape onsite at the actuator's end-use location. This process also made it difficult to splice sections of ServoBelt together - which is essential when building systems with long travel axes - requiring higher attention to detail and cleanliness.
Improving on the earlier design, ServoBelt now has a "rack" of teeth molded directly into the actuator's aluminum carrier. The rack offers precision tooth forms identical to the static belt it replaces and is molded from an equally rugged polyurethane - with a 50 Shore D hardness and minimum 4,500 psi tensile strength. The design now allows integrators to splice ServoBelt sections just as easily as they would with a traditional rack-and-pinion, using a simple tool similar to a tooth rack. It also offers significantly more resistance to tear-out forces than the earlier design.
The latest generation of ServoBelt includes the new molded belt trays, along with QR codes to take personnel directly to the splicing instructions on the Bell-Everman website.

Featured Product
3D Vision: Ensenso B now also available as a mono version!
This compact 3D camera series combines a very short working distance, a large field of view and a high depth of field - perfect for bin picking applications. With its ability to capture multiple objects over a large area, it can help robots empty containers more efficiently. Now available from IDS Imaging Development Systems. In the color version of the Ensenso B, the stereo system is equipped with two RGB image sensors. This saves additional sensors and reduces installation space and hardware costs. Now, you can also choose your model to be equipped with two 5 MP mono sensors, achieving impressively high spatial precision. With enhanced sharpness and accuracy, you can tackle applications where absolute precision is essential. The great strength of the Ensenso B lies in the very precise detection of objects at close range. It offers a wide field of view and an impressively high depth of field. This means that the area in which an object is in focus is unusually large. At a distance of 30 centimetres between the camera and the object, the Z-accuracy is approx. 0.1 millimetres. The maximum working distance is 2 meters. This 3D camera series complies with protection class IP65/67 and is ideal for use in industrial environments.
