Lead Screws High-Quality Components for Smooth, Precise and Reliable Positioning

Thomson - the Choice for Optimized Motion Solution Often the ideal design solution is not about finding the fastest, sturdiest, most accurate or even the least expensive option. Rather, the ideal solution is the optimal balance of performance, life and cost. Quickly Configure the Optimal Linear Motion Solution Thomson has several advantages that makes us the supplier of choice for linear motion technology. • Thomson owns the broadest standard product offering of mechanical motion technologies in the industry. • Modified versions of standard product or white sheet design solutions are routine...

Company Overview The very best of the Thomson, Warner, BSA and Neff ball and lead screw lines are now combined to form the most complete product offering in the industry Thomson has a long history of manufacturing quality lead screws. Our roots are planted in four separate companies that held strong and definitive footholds in the market. Those companies — Ball Screws & Actuators Co, Warner Linear, Thomson Industries, and Neff Automation — now form the nucleus of the Thomson lead screw business. Founded in 1971, the Ball Screws & Actuators Co. (BSA) was a pioneer and leader in precision plastic...

Lead Screws Technology ComparisonThomson Lead and Ball Screws Are Your Best Choice for Linear Motion Thomson's comprehensive range of lead and ball screws outperform other linear motion methods and allows you to find the optimal solution for your positioning needs. Compared to bulky, noisy and expensive hydraulic or pneumatic systems, Thomson lead and ball screws are compact, quiet and affordable. In addition, there's no need for pumps, hoses, fluids or shop air. This eliminates fire, safety and health hazards due to leaking fluid or other contaminants typically associated with these types of...

Advanced Anti-Backlash Supernuts®XCM 1800 XCMT 1800 C1— Our smallest anti-backlash nut design ever. The XCM 1800 uses the same patented^ ActiveCAM™ mechanism as its larger siblings in a miniaturized package. This allows backlash free operation in space critical applications requiring high accuracy and low drag torque. This cost effective solution is available in either flanged or threaded versions. TriCoat® PTFE dry film lubricant is available as an option on most screws. XCMF 1800 Note: See Screw Section on page 33. Specify XCMT or XCMF when ordering, see drawings at right. * V-Thread screws,...

Lead Screws Advanced Anti-Backlash Supernuts®XC 2500 XCT 2500 0A The XC Mode assembly is the most advanced anti-backlash nut design. The unique patented^ ActiveCAM™ accomplishes high axial stiffness and the absolute minimum drag torque. This advantage produces assemblies that cost less, perform better and last longer. The ActiveCAM automatically adjusts for wear, ensuring zero backlash for the life of the nut. XCF 2500 Note: See Screw Section on page 33. Specify XCT or XCF when ordering, see drawings at right. * V-Thread screws, see page 36. t Patent No. 5839321
