About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X280SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless steel round-body mini cylinder handles demanding 280 mm stroke tasks. The Ø25 bore operates on a 1/8" port and conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for straightforward design integration.
The rolled stainless barrel and rod resist mild corrosion, giving a real edge over painted alternatives in damp or washdown settings. With a 245.3 N push rating at 0.5 MPa, plan for about 147 N of actual work, which equates to lifting roughly 12.5 kg vertically with a 2:1 safety margin. The built-in -S piston magnet supports CMSG, DMSG and EMSG switches, while fixed TPU bumper pads absorb end-of-stroke impact.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X280SCA Is Used
Package Diverting Arms
Provides the 245.3 N push force needed to swing heavy cardboard cartons across a stainless steel conveyor belt in distribution hubs.
Lab Sample Ejection
Handles the 280 mm extraction stroke to push prepared specimen trays out of a chemical testing station using DMSG electronic sensors.
Pouch Forming Press
Delivers consistent downward pressure to seal and press liquid food pouches, where the stainless construction survives daily washdowns.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X280SCA the Right Cylinder?
When sizing this 280 mm stroke unit, consider the neighbouring bores: a Ø20 generates 157.0 N push at 0.5 MPa, while a Ø32 offers 402.2 N if you need substantially more power. Because this SKU features the CA rear pivot cover, it is ideal for clevis mounting. Note that a standard cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only decelerate the stroke end rather than locking the load, so deploy an external rod lock or pilot check valve for suspended loads. The 1/8" port and M10x1.25 male rod thread are fixed by the Ø25 bore.
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 MI25X280SCA FAQ
This double-acting cylinder pushes 245.3 N and pulls 206.1 N at 0.5 MPa. At 0.7 MPa, push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. It uses a 1/8" air port and operates between 30-800 mm/s.
This unit features a CA rear pivot cover for clevis mounting. A standard cylinder drifts when air is lost or the valve is centred; the fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. Use an external rod lock or pilot check valve to hold suspended loads securely.
