Airtac MI25~40 Stainless Steel Mini Cylinder MI25X60U
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X60U is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 60mm 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.

About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X60U
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust actuation tasks. The Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it an edge over painted alternatives in damp or washdown environments. Fixed TPU bumper pads absorb stroke-end impacts.
Because the 245.3 N rating leaves little room for friction, plan for a safe working load of about 147 N. Vertically, this translates to lifting roughly 12.5 kg with a 2:1 safety margin. This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches. The rear U cover provides a 90-degree mounting interface for tight spatial constraints.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X60U Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 245.3 N push force to redirect heavy cartons onto secondary belts.
Pallet Stopper Arm
Deploys a 60 mm stroke physical stop to halt pallets at a workstation, relying on the stainless build for warehouse durability.
Clamp Actuator
Secures mild steel plates during a machining process, applying a safe working load of 147 N without shifting the workpiece.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X60U the Right Cylinder?
When sizing this 60 mm stroke model, verify your actual load against the 147 N safe working limit. If you need less force, the Ø20 bore provides 157.0 N push at 0.5 MPa; stepping up to the Ø32 bore yields 402.2 N. Remember that venting the air causes the piston to drift, as the TPU bumpers only decelerate the stroke end rather than locking the rod. Use a pilot-operated check valve for position holding.
The 1/8" port matches the standard Ø25 bore specification. You can utilize LB foot, FA flange, SDB pivot, or TC trunnion brackets alongside the U back cover. If your machine requires adjustable end-cushioning for high-speed cycles, consider the MIC variant instead of this fixed-bumper build.
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 MI25X60U FAQ
This double-acting cylinder uses a 1/8" air port. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet required for switches. You must select the -S variant to use CMSG, DMSG, or EMSG sensors. The unit features a 90-degree U back cover and conforms to ISO 6432 mounting dimensions.
