Thomson has over 70 years of ball screw and lead screw support and offers both metric and imperial options, outperforming other actuation methods. Compared to bulky, noisy and expensive hydraulic or pneumatic actuator systems, Thomson ball screws and lead screws are compact, quiet and very affordable. In addition, there’s no need for pumps, hoses, fluids or shop air, eliminating many fire, safety and health hazards.
Thomson precision rolling machines ensure accurate positioning to 0.003 in/ft, and our PTFE coating process produces ball screw assemblies that have less drag torque, extending performance life. All of our standard plastic ball screw nut assemblies use an internally lubricated Acetal, providing excellent lubricity and wear resistance with or without additional lubrication. For significantly higher loads, ball screws with standard bronze nuts use SAE 660 bearing bronze, which provides high load capacity with good PV performance.
Thomson ball screws and lead screws differ in design, quality, materials, manufacturing and application support, all factors that affect performance and extend life. Both our ball screws and lead screws come in a full range of diameters, leads and ball nut configurations, in either preloaded or non-preloaded types, all in industry-standard envelopes.
