Lead Screws

The largest range of lead screw, acme screws and trapezoidal screws in the world. Our screws range in size from 1-50mm in diameter with an incredible amount of nut options with varying materials and models. Buy online today.

Linear Actuators

A variety of models configured in travel lengths to 1,300 mm and deliver loads/forces up to 1,500 lbf. Actuators are assembled with lead screw or ball screw drives. Stepper and servo motors available.

Linear Slides

Series 200 Linear Slide Systems - a completely assembled system that includes: linear guidance, carriage plate and Acme screw assembly. Many configurable options are available.


Linear Spline Shafts provide anti-rotation for one axis motion or a drive mechanism with rotation for two axes of motion. Anti-backlash bushings and custom end machining available.


Ball screws and Acme screws require end machining matched with precision bearing mounts. We offer both the bearing mounts and end machining as a complete assembly.

Electric Cylinders

Lead screw or ball screw driven electric cylinders assembled with Intelligent stepper motors and a variety of mounting options. Sensors, encoders and custom mounts available.


High performance lubricants for medical, aerospace, electronic and military applications. Buy online today.


Profile Rail Linear Actuators offer smooth, clean and quiet linear positioning. The PRA is built with either lead screw or ball screw drives.

Services and Custom Solutions

Custom Linear Actuators

When design engineers need a custom solution, we can help select a linear actuator that utilizes a lead screw, ball screw, belt or roller screw drive that best fits your application. These new solutions, can combine catalogue products and custom components to provide cost-effective sub-systems.

Subassembly Services

We can help streamline your supply chain by assembling your complete linear actuation system. Assembly of couplings, bearings, pulleys or additional linear actuators to build X,Y and Z linear gantries. Our assembly department also performs cycle testing and validation testing that enables our products to go directly from your dock to stock.

End-Machining Services

We offer complete end machining services for 1-10,000 pieces and diameters ranging from 1.6 to 75mm. Lead screws can be provided cut to length or with a range of standard end modifications suitable for interfacing with ball bearings, circlips, couplings, pulleys, gears or our standard end mounts.


To help design engineers develop prototypes quickly and effectively we are able to supply small quantities. Our manufacturing facilities enable larger quantities to be supplied for full production requirements, available with scheduled delivery, consignment stocking and stock management services.

Custom Lead Screw and Nut Design

If you don't see the screw size that you need - just ask! Many of the screw we manufacture every year are brand new diameter and lead combinations. If you need to math a lead screw to your motion profile or to a motor you have already selected, we can design and manufacture a new screw for your application.

In-House Rolling Die Manufacturing

We are one of the few lead screw manufacturing companies in the world that design and produce thread rolling dies. If you need a completely custom lead screw design, we can design the thread form, grind the dies and roll the screw for you faster than any company in the world.
