SMC 10-CM2L20-200Z | Clean Room Standard Air Cylinder CM2 Series 20mm Bore 200mm Stroke Foot Mount (L-Type) Double-Acting Auto-Switch Ready

The SMC 10-CM2L20-200Z is a clean room specification standard air cylinder from the CM2 series with a 20mm bore, 200mm stroke, and L-type foot mounting. Part number decoded: CM2 = standard round body stainless tube, L = foot mount type (bottom-mounted feet integrated into the cylinder), 20 = bore mm, 200 = stroke mm, Z = auto-switch groove. The 200mm stroke is an exceptionally long travel for a 20mm bore, creating a high stroke-to-bore ratio suited for extended-reach, low-force clean room operations.

The L-type foot mount integrates mounting feet directly onto the cylinder body, allowing the cylinder to be mounted on a horizontal surface with the rod extending parallel to or perpendicular from the mounting plane. This is the preferred mounting for conveyor-mounted applications, horizontal push/pull mechanisms, and long-travel shuttle operations. At 20mm bore, the cylinder generates approximately 188N at 0.6 MPa through 200mm of travel. A 200mm stroke at 20mm bore requires careful consideration of rod buckling under compressive loads — for pushing applications at full stroke, ensure the load does not exceed the maximum allowable compressive force for the rod diameter at this extension.

The CM2L20-200Z offers maximum CM2 reach at 20mm bore with foot mounting. For basic mount at the same stroke, use CM2B20-200Z. For more force at 200mm stroke, step up to CM2L25-200Z (25mm bore) or CM2L32-200Z (32mm bore). For front flange, CM2F20-200Z. The stainless steel tube resists corrosion in humid environments. Clean series (10-) fluorine grease, Particle Grade 1. RoHS compliant. Compatible with D-series auto switches and AS speed controllers.
