Rollon (Hackettstown, NJ) has in - troduced the Actuatorline TT series of high-precision linear positioning stages. Available in a range of sizes and configurations, the stages are suited for use in robotic handling systems, semiconductor equipment, X-Y-Z Cartesian robots, machine tools, and automated assembly lines. The stages are made of anodized aluminum extrusions, and bodies are CNC machined on all outer surfaces and where mechanical components are attached, such as ball bearing guides.For the drive system, the stages use preloaded precision ball screws along with ball screw nuts available in ISO 5 and ISO 7 accuracy classes. Long pitch screws support high speeds. Precision guides with ground rails and preloaded blocks ensure accurate parallelism, and rigidity and reduced wear. Body dimensions measure 100 x 50 mm, 155 x 60 mm, 225 x 75 mm, and 310 x 105 mm. Maximum dynamic axial load capacities range from 336 to 3,800 N, and stroke lengths range from 46 to 3,000 mm.
