CDUK20-50D Applications
The CDUK20-50D combines a 20 mm bore with a 50 mm stroke, giving useful reach and thrust from a compact free mount body. The non-rotating rod prevents tool spin under off-axis load, which suits pushing, transferring, lifting and clamping of small assemblies, as well as guiding chutes, stops and diverters. Direct mounting on multiple faces simplifies installation in tight machine frames, and the built-in magnet enables SMC auto switches for stroke-end confirmation.
