Linear actuators CLA Series and CLB Series 3.1 MANUFACTURING FEATURES Input drive: worm gear - precision helical wheel, geometric design for high performance, involute profile ZI (UNI 4760 : Part 4), low angular backlash. Worm in case hardened steel 20 MnCr 5 (UNI EN 10084), with thread and input shafts ground. Helical wormwheel in bronze EN 1982 – CuSn12-C. Housing: designed and manufactured in monobloc form to obtain a compact body able to sustain heavy axial loads and high machining accuracy. High quality materials are used: ▪ castings in aluminium alloy EN 1706 AC-AlSi6Cu4 ▪ castings in...
