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.


We focus on our customers by helping to develop prototype lead screws and linear actuators quickly. 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 screws we manufacture every month are brand new diameter and lead combinations. If you need to match a lead screw to your motion profile or to a motor you have already selected, we can design and manufacture a new screw exactly 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.
