Since 1985, Rolled Threads Unlimited has been offering a broad range of capabilities including acme, unified, metric, and trapezoidal thread forms as well as knurling and rolled worms. Lead screws are also among our products, serving the linear motion, small motor and other markets as well. Stainless steel, carbon steel and heat treated alloys some of the available lead screw materials.
Ball screws are mechanical linear actuators that consist of a screw shaft and a nut that contain a ball that rolls between their matching helical grooves. The primary function of ball screws is to convert rotational motion to linear motion. Ball nuts are used in...
Lead Screw
A lead screw is a kind of mechanical linear actuator that converts rotational motion into linear motion. Its operation relies on the sliding of the screw shaft and the nut threads with no ball bearings between them. The screw shaft and the nut are directly moving against each other on...
Linear Actuators
A linear actuator is a means for converting rotational motion into push or pull linear motion, which can be used for lifting, dropping, sliding, or tilting of machines or materials. They provide safe and clean...
Linear Slides
Linear slides, also referred to as linear guides or linear-motion bearings, are types of bearings that allow smooth and near-frictionless motion in a single axis. Machine tools, robots, actuators, sensors, and other mechanical equipment often require moving components in a straight line in any of the three-dimensional axes...
Linear Rails
Linear Rails are ideal for moving items through a production process with great precision and as little friction as possible if creating, packing, and distributing products. Linear Rail is a type of gadget that...
Roller Tables
A roller table is a small, stiff, limited linear guide device with an integrated cross-roller guide. Electrical or mechanical drive systems are frequently used to move a roller table, making it easy to transfer heavy loads...
