About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X65SCM
Generating up to 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial workloads within a compact footprint. The stainless-steel barrel and piston rod supply reliable mild corrosion resistance, outperforming painted alternatives in damp or washdown environments. It features a 1/8" air port and a CM round end rear cover. Equipped with a built-in piston magnet (-S), it supports CMSG, DMSG and EMSG switches for precise position detection.
For practical sizing, plan for roughly 241 N of real work at 0.5 MPa, which safely lifts about 20.5 kg vertically with a 2:1 margin. Fixed TPU bumper pads absorb end-of-stroke impact to protect the mechanism. Because this is a Ø32 bore, it is a non-ISO-6432 round-body unit, offering a larger force output than standard mini sizes.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X65SCM Is Used
Package Diverting
Actuates routing gates on packaging conveyors, using its 402.2 N thrust to push heavy cartons onto secondary tracks at high cycling speeds.
Clamp Fixtures
Secures metal or wood workpieces in CNC machining fixtures, providing reliable holding pressure without overwhelming delicate tooling setups.
Pallet Stops
Functions as a robust pneumatic stop mechanism in automated pallet handling lines, halting loads up to 20.5 kg safely during transit.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X65SCM the Right Cylinder?
When sizing this 32 mm bore, stepping down to a Ø25 MI yields 245.3 N push at 0.5 MPa, while stepping up to a Ø40 MI provides 628.3 N. This model occupies a strong middle ground for medium-force tasks. The included -S magnet pairs directly with CMSG, DMSG or EMSG sensors, and the CM round end cover offers a clean rear profile for tight mounting spaces.
Remember that venting the air supply or centering the control valve will cause the rod to drift, as the TPU bumpers only decelerate the stroke end rather than locking the piston. To suspend a load safely during a pressure drop, integrate an external rod lock or a pilot-operated check valve into your circuit. With a 65 mm stroke, keep side-loading forces minimized to prevent rod bending.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MI25~40 Stainless Steel Mini Cylinder MI32X65SCM FAQ
This double-acting cylinder delivers a push of 402.2 N and a pull of 345.6 N at 0.5 MPa. At 0.7 MPa, the push is 563 N and the pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a 1/8" air port and a Ø12 mm piston rod with an M10x1.25 male thread.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the rod near the stroke end; they do not act as a brake. For vertical loads, you must install an external rod lock or a pilot-operated check valve to prevent falling.
