About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75U
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 75 mm stroke operates at speeds from 30-800 mm/s, while fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning. Its 1/8" port feeds the 25 mm bore to generate 206.1 N of pull force on the return cycle.
The rolled stainless barrel and rod shrug off mild corrosion, making it superior to painted alternatives in damp environments. Because it adheres to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. For practical sizing, plan for roughly 147 N of actual work at 0.5 MPa, which means it lifts about 12.5 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75U Is Used
Package Diverting Gate
Actuates a routing flap on a packaging conveyor to push 10 kg cartons onto secondary tracks without stalling.
Textile Loom Tensioner
Maintains consistent fabric tension by applying up to 147 N of regulated push force against a spring-loaded guide arm.
Pallet Stacking Stopper
Extends 75 mm to halt empty pallets on a roller bed, using its stainless build to resist ambient warehouse humidity.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75U the Right Cylinder?
When sizing this 25 mm bore, the smaller 20 mm option yields 157.0 N of push, while the larger 32 mm bore provides 402.2 N at 0.5 MPa. Choose this model when your load sits closer to 245.3 N. The U suffix denotes a 90-degree rear cover, orienting the back port sideways for tight spatial constraints. You can mount the body using LB foot brackets, FA flanges, SDB pivot blocks or TC trunnions.
Remember that venting the air or centering the valve causes the piston to drift, as the TPU bumpers only soften the end-of-stroke impact rather than locking the rod. To suspend a load safely mid-stroke, install an external rod lock or a pilot-operated check valve. If your machine requires position sensing, select the -S magnet variant instead of this non-magnet SKU.
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 MI25X75U FAQ
This 25 mm bore cylinder features a 1/8" port and a 10 mm rod. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, increasing to 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
Yes, it uses standard ISO 6432 mounting dimensions compatible with LB, FA, SDB and TC brackets, plus a 90-degree U back cover. However, this specific SKU lacks a magnet, so you cannot attach CMSG, DMSG or EMSG switches without upgrading to the -S variant.
