The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X600SCMLB is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 600mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.
Generating 245.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial work over a 600 mm travel distance. Because 600 mm exceeds the 500 mm standard stroke limit for a Ø25 bore, this specific SKU is manufactured as a made-to-order unit. The stainless-steel barrel and Ø10 piston rod naturally resist mild corrosion, giving it a distinct advantage over painted alternatives in damp or washdown settings.
Equipped with an -S piston magnet, the unit readily accepts CMSG, DMSG, or EMSG switches for position sensing. It conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises. For practical sizing, plan for roughly 147 N of actual work at 0.5 MPa, which equates to lifting about 12.5 kg vertically with a 2:1 safety margin. The 1/8" port and M10x1.25 male rod thread ensure solid pneumatic and mechanical connections.

MI-family variants: MI / MIC (double acting ±cushion), MSI / MTI (single acting push / pull), MID / MICD (double rod ±cushion), MIJ / MICJ (adjustable stroke ±cushion). Back covers CA / U / R / CM. Mounting LB / FA / SDB / TC.
Pushes packages across a wide conveyor belt using the extended 600 mm stroke, relying on the 245.3 N thrust to deflect heavy cartons without stalling.
Elevates components to an upper tier, safely handling around 12.5 kg of actual payload while the stainless build withstands humid storage environments.
Actuates a distant safety guard on a machining cell, using the LB foot bracket and CM round end to secure the lengthy 600 mm extension firmly.
When sizing this actuator, the neighboring Ø20 bore provides 157.0 N of push at 0.5 MPa, while stepping up to the Ø32 yields 402.2 N, helping you bracket your force needs. This model includes an LB foot mount and a CM round rear cover for stable base mounting. Because the 600 mm stroke is quite long for a mini cylinder, carefully manage side loads to prevent rod bending and premature seal wear. The fixed TPU bumper pads only decelerate the stroke end; they do not act as a lock. If the load must remain suspended during air loss or valve centering, the piston will drift, so an external rod lock or pilot-operated check valve is required.
Quick checklist
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M10x1.25.
The 600 mm stroke is a non-standard, made-to-order length exceeding the 500 mm maximum. The fixed TPU bumpers only decelerate the stroke end and do not function as a brake. The piston will drift if air is lost, so an external rod lock or pilot check valve is needed to hold a suspended load.
