About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50SR
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X50SR is a double-acting round-body mini cylinder built for demanding actuation. The stainless-steel barrel and piston rod provide excellent mild-corrosion and washdown resistance, outperforming painted alternatives in damp environments. A built-in piston magnet allows seamless integration with CMSG, DMSG, or EMSG reed and electronic switches for position sensing.
This 32 mm bore unit features a 50 mm stroke and a 1/8" port. It uses fixed TPU bumper pads to decelerate the piston at stroke ends, rather than an adjustable air cushion. For practical sizing, plan for a safe working load of roughly 241 N, which means it can vertically lift about 20.5 kg with a 2:1 safety margin.

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.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 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.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50SR Is Used
Package Diverting Gate
Actuates a routing flap on a stainless-steel conveyor handling wet produce, using the 402.2 N thrust to deflect heavy cartons reliably.
Pallet Stopping Arm
Serves as a robust stopper arm in a distribution hub, where the 50 mm stroke halts pallets and the TPU bumpers absorb the repeated impact.
Vial Capping Press
Provides the precise downward clamping force for securing caps on pharmaceutical vials, benefiting from the corrosion-resistant stainless build during washdowns.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50SR the Right Cylinder?
When sizing this 32 mm bore actuator, compare it against its neighbours: the smaller Ø25 MI yields 245.3 N of push at 0.5 MPa, while the larger Ø40 MI provides 628.3 N. The MI32X50SR is the right choice when your application requires that middle-ground force. It features an R back cover with an axial-in port to simplify plumbing in tight spaces.
Remember that a standard double-acting cylinder drifts if air pressure is lost or the valve is centred; the TPU bumpers only soften the end-of-stroke impact and do not function as a locking brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. The included -S magnet enables position feedback, and you can mount the body using LB foot, FA flange, SDB pivot, or TC trunnion brackets.
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 MI32X50SR FAQ
This 32 mm bore double-acting cylinder has a 1/8" port and an M10x1.25 male rod thread. 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.
No, the base MI uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion (for that, look at the MIC variant). However, because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG switches directly onto the body for electronic position sensing.
