The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI32X600SCM is a genuine double acting round-body mini air cylinder with a Ø32mm bore and 600mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments.
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial actuation tasks. The 600 mm stroke is a non-standard, made-to-order length that exceeds the 500 mm maximum standard for this bore, making it ideal for applications requiring extended travel. Its stainless-steel barrel and piston rod resist mild corrosion and washdown environments better than painted alternatives. Equipped with a built-in magnet (-S), it supports CMSG, DMSG and EMSG sensors, while the CM round end cover provides a clean rear profile.
For practical sizing, plan for a safe working load of roughly 241 N, which is about 60 percent of the 0.5 MPa push rating. This equates to lifting a 20.5 kg part vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb the impact at stroke extremes, though they decelerate rather than provide adjustable cushioning. Air operates through a 1/8 inch port, driving the 12 mm rod at speeds between 30 and 800 mm/s.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.

| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

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 heavy packages across a 600 mm transfer gap on a packaging conveyor, utilising the 402.2 N thrust to overcome friction.
Raises 20 kg tote bins between machinery levels, safely operating within the calculated 20.5 kg vertical lift margin.
Drives a stainless-steel gating mechanism in a damp food-processing line where the riveted round body resists mild corrosion.
When sizing this 32 mm bore, the adjacent 25 mm option yields 245.3 N of push at 0.5 MPa, whereas stepping up to the 40 mm bore provides 628.3 N. This model sits perfectly in the middle for medium-force tasks. Because the 600 mm stroke is a non-standard, made-to-order length, carefully verify your side-load geometry; extended rods are prone to bending without proper guidance.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the TPU bumpers only soften the end-of-stroke impact and act as neither a brake nor a lock. To suspend a load safely during an emergency stop, incorporate an external pilot-operated check valve or a dedicated rod lock.
Quick checklist
This 32 mm bore cylinder features a 1/8 inch air port. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG electronic switches. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
