SMAC Moving Coil Actuators today launched its LBR and LDR series linear rotary actuators. The company says these actuators are equipped with Smart Screwdriver technology for precise screw insertion and tightening in automated manufacturing processes.
Carlsbad, California-based SMAC says these new actuators will “set new standards for efficiency, accuracy and reliability.”
According to the company, LBR and LDR actuators can be used in industrial applications such as electronic assembly, where small screws and delicate materials pose unique challenges. SMAC claims its actuators address these challenges “head-on with industry-leading features and advanced features.”
“Companies choose SMAC linear rotary actuators for their screw drive requirements due to the unique challenges posed by small, delicate screws and the need for zero-defect production,” said Ed Neff, founder and CEO of SMAC. “LBR and LDR are game-changers in automated manufacturing, providing unparalleled precision, flexibility and real-time feedback.”
SMAC design for precise handling
Founded in 1990, SMAC says it aims to replace older technologies such as pneumatic cylinders and electric ball screw actuators. The company manufactures a variety of precision programmable electric actuators based on patented moving coil technology.
The company claimed its electric actuators are unique because force, position and speed can all be programmed. SMAC is designed to operate at high or ultra-low speeds with submicron accuracy and repeatability capable of verifying as precise as 1 ms response time.
SMAC says these characteristics make its actuators ideal for a wide range of positioning, measurement, inspection and pick-and-place applications.

LBR and LDR promise thread-matching, defect-free production.
As manufacturers increasingly seek systems to process small screws with accuracy and reliability, SMAC says its LBR and LDR lines will be the top choices.
“Our LBR and LDR linear rotary actuators represent a significant advancement in automated manufacturing technology,” said Neff. “With its SMART DRIVER capabilities and unmatched precision, it is poised to revolutionize the way screws are inserted and tightened across a variety of industries.”
These two lines of linear actuators can solve many challenges. First, SMAC emphasized its ability to handle goods with precision. Small screws are notoriously difficult to assemble, often resulting in problems such as misaligned threads or damaged tapped hole threads.
The company noted that LBR and LDR’s smart driver technology ensures precise screw insertion by detecting the top of the screw, verifying thread match, and monitoring screw movement in real time.
LBR and LDR also eliminate cross-threading by ensuring thread matching every time, SMAC said. Using a 1um encoder, the actuator rotates counterclockwise, first recognizes the drop in thread pitch, defines the thread, and then begins clockwise rotation to tighten the screw.
Finally, according to SMAC, these actuators offer zero-defect production. In industries such as medical, aerospace and automotive where zero-defect production is uncompromising, LBR and LDR offer high reliability, the company said.
SMAC said the actuator’s advanced features allow it to 100% verify the correct process for a perfect assembly every time.
The company also offers a wide range of linear rotary actuators for all applications, from very small to large screws. We are also adding an integrated closed-loop torque sensor option to our LBR and LDR actuators.
