SMC 10-CM2F40-160Z | Clean Room Standard Air Cylinder CM2 Series 40mm Bore 160mm Stroke Front Flange Mount Double-Acting Auto-Switch Ready Stainless Tube

The SMC 10-CM2F40-160Z is a clean room specification standard air cylinder from the CM2 series with a 40mm bore, 160mm stroke, and front flange mounting. Part number decoded: CM2 = standard round body stainless tube, F = front flange, 40 = bore mm, 160 = stroke mm, Z = auto-switch groove. The 160mm stroke is the longest standard front-flange option in the CM2F40 range, providing extended reach for deep-travel clean room applications.

At 754N force (0.6 MPa) through 160mm of travel, this cylinder excels in long-reach pressing operations, deep-insertion mechanisms, full-width conveyor diversion, and multi-position transfer. The front flange centralizes the load path through the cylinder's axis, reducing lateral stress on the mounting points compared to offset foot or bracket mounting — particularly important at longer strokes where cantilever forces are amplified. The stainless steel tube construction provides corrosion resistance in humid clean room environments. The same flange bolt pattern as CM2F40-100Z through CM2F40-160Z ensures interchangeability.

The CM2F40-160Z is the longest front-flange CM2 at 40mm bore. For shorter travel, CM2F40-125Z or CM2F40-100Z reduce overall length. For basic mounting at this stroke, use CM2B40-160Z. The 160mm stroke extends 35mm beyond the CM2F40-125Z and 60mm beyond the CM2F40-100Z. CM2F40 variants from 100mm to 160mm share the identical front flange bolt pattern. Clean series (10-) fluorine grease, Particle Grade 1. RoHS compliant. Compatible with SMC D-A auto switches and AS speed controllers. Stainless steel tube construction throughout.
