WEISS SR145D Linear Actuator
The SR-D series of actuators combines the high force and precision characteristics of a ball screw drive with the robustness of a dual profile rail guideway design. The mechanism is housed within a precision extruded aluminum profile reducing internal contamination and providing several mounting options. The high-quality ball screws are manufactured to either ISO7 or ISO5 tolerance class and are available with multiple lead options on each of four actuator sizes.
-
- Two standard carriage lengths, as well as multiple carriages, are available to reinforce load capacity and increase bearing lifetime
-
- Optional connection plate with T-slots and precision dowel holes simplifies accurate attachment of tooling to the carriage
-
- Optional guideway seals further reduce the risk of internal contamination
-
- Variety of accessories including limit switches, mounting hardware, motor adapters and couplers
-
- Full range of connection adapters to streamline the design of multi-axis configurations with other WEISS actuators

Linear Actuator FAQs
The following frequently asked questions provide a quick overview of the WEISS SR-D Series Linear Actuators. These precision ball-screw driven linear units are designed to deliver accurate positioning, high rigidity, and reliable performance in demanding automation environments. The FAQs below address common questions related to application use, configuration options, and the advantages of SR-D actuators in modern automated production systems.
WEISS SR-D actuators are precision ball-screw driven linear units designed for applications that require accurate positioning, high rigidity, and smooth motion. They are commonly used in automated assembly systems, pick-and-place stations, test equipment, and material handling applications where precise linear movement is required.
A ball-screw driven actuator like the WEISS SR-D provides higher positioning accuracy, greater rigidity, and better repeatability than belt-driven systems. Ball screws are typically preferred for applications with shorter strokes and higher force requirements, while belt drives are more suitable for longer travel distances and higher speeds with lighter loads.
WEISS SR-D actuators are available in multiple frame sizes with configurable stroke lengths depending on the application requirements. The stroke is defined during configuration, allowing the actuator to be optimized for the exact travel distance required in the machine or automation system.
WEISS SR-D actuators can be configured with a single carriage or multiple carriages on the same linear unit. Multiple carriage configurations are useful when supporting larger loads, synchronizing tooling, or maintaining fixed spacing between mounted components.
WEISS SR-D actuators are widely used in industrial automation sectors including electronics manufacturing, automotive production, packaging machinery, and precision assembly systems. Their rigidity, accuracy, and modular integration make them well suited for modern automated production environments.
