Airtac MI25~40 Stainless Steel Mini Cylinder MI25X80SCASDB
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X80SCASDB is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 80mm 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 MI25X80SCASDB
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust linear motion. 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 a real edge over painted alternatives in damp or washdown settings. Built-in fixed TPU bumper pads decelerate the piston at stroke ends to soften impact.
The ISO 6432 mounting interface lets this unit drop directly into standard mini-cylinder brackets and clevises. Because the -S magnet is present, you can mount CMSG, DMSG or EMSG reed and electronic switches for position sensing. Plan for roughly 147 N of actual work at 0.5 MPa to maintain a safe margin, which translates to lifting about 12.5 kg vertically with a 2:1 safety factor.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X80SCASDB Is Used
Package Diverter Arm
Swings a lightweight routing gate on packaging lines, using the SDB pivot block to articulate smoothly while handling the 12.5 kg vertical lift equivalent.
Textile Loom Tensioner
Maintains consistent fabric tension in damp textile manufacturing environments, leveraging the stainless steel construction to resist humidity and washdown.
Pallet Stacking Stop
Acts as a robust pneumatic stop for medium-weight pallets, absorbing end-of-stroke impact through fixed TPU bumper pads without needing an adjustable cushion.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X80SCASDB the Right Cylinder?
When sizing this 80 mm stroke unit, verify your payload against the 245.3 N push rating. If you need less force, the Ø20 bore provides 157.0 N at 0.5 MPa; stepping up to the Ø32 bore yields 402.2 N. This SKU includes a CA pivot clevis back cover and an SDB pivot-block accessory, ideal for articulating loads. The -S magnet enables position sensing, whereas a standard SKU cannot take a sensor.
Remember that a plain double-acting cylinder drifts when air is removed or a valve centres, as the TPU bumpers only soften the stroke end rather than locking the rod. To suspend a vertical load securely, fit an external rod lock or a pilot-operated check valve. Additionally, keep side-loading minimized on this 80 mm stroke to prevent rod bending and premature seal wear.
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 MI25X80SCASDB FAQ
This Ø25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. 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 force of 50 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centred, as the fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. You must use an external rod lock or pilot check valve to hold a vertical load. The included -S magnet allows CMSG, DMSG or EMSG sensors to track position.
