Straight-toothed sprocket wheel ZTR & ZR series

flange

HighForce ZTR & ZR For precise applications with thrust forces up to 12,000 lb., the HighForce ZTR and ZR rack & pinion drive systems are now available. These drives, which are available in seven sizes with backlash levels down to one arc-minute, are similar to the ZTRS drive systems but without the outboard bearing support. The drive pinions are flange mounted to the reducer output, providing tight integration of the driven load, while allowing replacement of the pinion if needed. For more economical and lighter duty applications with thrust forces up to 4,500 lb., planetary reducers with solid output shafts are also available for mounting bored pinions directly via keyways or compression couplings. These drives are perfect for a wide range of applications, such as traveling gantries & columns, pick & place robots, machine tools, CNC routers and material handling systems. Zero backlash rack & pinion drive systems are also possible by using two reducers to share driving the load during acceleration while removing the axis backlash to ensure precise positioning. Applications for these systems can be found in the Material Handling, Automation, Aerospace, Woodworking, Machine Tool and Robotics industries
