SMC 10-CDM2XB20-50 | 10-/11-CM2X Series Clean Room Low Speed Cylinder 20mm Bore 50mm Stroke Smooth Motion Control

The SMC 10-CDM2XB20-50 is a clean room specification low speed cylinder from the 10-/11-CM2X series, configured with a 20mm bore and 50mm stroke for controlled, smooth motion at reduced speeds. The CM2X series is specifically engineered to prevent the stick-slip motion phenomenon that causes jerky, uncontrolled movement in standard cylinders when operated at low speeds, delivering consistent, uniform travel velocity throughout the entire stroke length.

Why is a dedicated low-speed cylinder necessary for clean room applications? Standard pneumatic cylinders operated at low speeds exhibit stick-slip behavior caused by the transition between static and dynamic friction in the piston seals. This creates jerky, unpredictable motion that can damage delicate workpieces, cause positioning inaccuracy, and generate vibration-induced particles in clean room environments. The CM2X series uses specially designed seals and internal friction management to eliminate stick-slip, providing smooth, controllable motion at speeds as low as 10mm/s or less.

The 20mm bore with 50mm stroke targets precision applications including slow-approach workpiece contact, gentle part placement, controlled insertion operations, and any clean room automation task where impact-free, vibration-free motion is essential for product quality and particle control. Smooth cylinder operation also reduces acoustic noise in the clean room environment.

The "10-" clean series provides fluorine grease, clean room assembly, and particle generation grade 1 compliance. RoHS compliant and compatible with SMC clean series speed controllers for comprehensive low-speed motion control.
