Local Support Around the Globe Application Centers Global Manufacturing Operations Global Design & Engineering Centers Lead Screws , ball Screws and ball Splines A World Class Heritage Serves as Our Foundation 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 and ball Screws .
4 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 ball screw and lead screw business. Founded in 1971, the ball Screws & Actuators Co. (BSA) was a pioneer and leader in precision plastic nut, lead screw and ball screw technologies for Linear motion applications. Their custom and off-the-shelf solutions featured many patented products, including their ActiveCAM technology for eliminating backlash while increasing performance and wear life. Tollo Linear was founded in 1982 and manufactured Linear actuators, Linear drive units and handling components under a variety of trademarked product names. Its products were sold to direct customers, OEM manufacturers, and system houses throughout the world.
5 In 1989, Tollo Linear was purchased by Warner Electric and the new division became known as Warner Linear . Thomson Industries was the leading producer of Linear motion control products, including Linear actuators, ball Screws , Linear bearings and rails, and precision gearboxes. Its products were found in a range of precision motion applications in the medical, industrial, aerospace and mobile off-highway markets. Neff Automation was founded in 1905 and has since been a leading manufacturer of industrial products for Linear motion applications. In the past four decades Neff has become a market leader in high precision rolled ball Screws , providing solutions for customers all across the globe. The current lead screw and ball screw offerings combine the quality, strength and expertise of the distinct products and professionals at these four companies under the Thomson name.
6 The products set the solid foundation for the broad range of standard and custom lead and ball Screws available today. If past history and experience is an indication of what the future holds, Thomson is significantly poised to remain a prominent leader and pioneer in the ball screw and lead screw industry.

Lead Screws Offering smooth, precise, cost effective positioning, this is the just right solution for your application. Thomson BSA precision lead Screws are an excellent economical solution for your Linear motion requirements. For more than 30 years, Thomson BSA has designed and manufactured the highest quality lead screw assemblies in the industry. Our precision rolling machines ensure accurate positioning to in/. ft and our PTFE coating process produces assemblies that have less drag torque and last longer. All of our standard plastic nut assemblies use an internally lubricated Acetal providing excellent lubricity and wear ball Screws - Inch Series resistance with or without additional lubrication.
9 With the introduction of our new unique patent pending zero backlash designs, Thomson BSA provides assemblies with high axial stiffness, zero backlash and the absolute minimum drag torque to reduce motor requirements. These designs produce products that cost less, perform better and last longer. Both designs automatically adjust for wear insuring zero backlash for the life of the nut. For significantly higher loads, standard bronze nuts are available. Thomson ball Screws INCH SERIES.
