About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X100SR
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work in compact spaces. The riveted stainless barrel and Ø10 mm rod shrug off mild corrosion, making it far superior to painted aluminium in damp washdown environments. Equipped with a piston magnet, it accepts CMSG, DMSG, or EMSG switches for position sensing.
The Ø25 bore conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises. It breathes through a 1/8" port and features an R axial-in rear cover for tidy inline plumbing. For real-world sizing, plan for roughly 147 N of actual work at 0.5 MPa, which translates to safely lifting about 12.5 kg vertically with a 2:1 margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X100SR Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using its 245.3 N push force to reliably redirect parcels up to 12.5 kg onto secondary chutes.
Textile Loom Tensioner
Maintains consistent yarn tension in a humid manufacturing environment, leveraging the stainless steel construction to resist mild corrosion and washdown.
Pallet Stacking Stopper
Deploys a 100 mm physical stop block to halt incoming pallets at a packing station, absorbing end-of-stroke impact through its fixed TPU bumper pads.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X100SR the Right Cylinder?
When sizing this 100 mm stroke model, compare it against its neighbours: a Ø20 bore provides 157 N of push at 0.5 MPa, while stepping up to a Ø32 yields 402 N. This Ø25 strikes a middle ground with 245.3 N push and 206.1 N pull at 0.5 MPa. If your process loses air or the valve centres, the piston will drift; the fixed TPU bumper pads only decelerate the stroke end rather than locking the load, so add an external rod lock or pilot check valve if you need strict position holding.
The included -S magnet enables electronic and reed sensor tracking. You can mount it via LB foot, FA flange, SDB pivot, or TC trunnion hardware. At a 100 mm extension, mind the side-load geometry to avoid rod bending, and utilize the M10x1.25 male rod thread for secure tooling attachment.
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 MI25X100SR FAQ
This double-acting cylinder operates on a 1/8" port and generates 245.3 N push and 206.1 N pull at 0.5 MPa. At 0.7 MPa, push increases to 343.4 N and pull to 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
Yes, the built-in -S magnet supports CMSG, DMSG, and EMSG switches for tracking. It operates at speeds of 30-800 mm/s. Note that it uses fixed TPU bumper pads to decelerate the stroke end; for adjustable air cushioning at high speeds, consider the MIC variant.
