SMC Corporation MY1B20G-100-M9BWL Rodless Cylinder

The SMC MY1B20G-100-M9BWL is a 20 mm bore, 100 mm stroke mechanically jointed rodless cylinder with a basic-mount configuration for compact linear actuation. It uses a one-piece carriage and piston that travel the full stroke inside a sealed housing, with an inner seal belt to maintain air pressure and an outer dust seal band to guard against contaminants, plus standard air cushions for smooth motion and optional external shock absorbers. The M9BWL suffix denotes an auto-switch option (reed-switch type) for position sensing integrated with the rodless cylinder. This design delivers a smaller footprint and low profile compared with rod-style cylinders while providing bidirectional, double-acting actuation suitable for compact automation tasks.
