Airtac MAC Stainless Steel Mini Air Cylinder MAC25X25SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X25SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 25mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X25SU
Flat end covers and a smooth round barrel mean the MAC25X25SU can be gripped by simple brackets or clamps almost anywhere along its length. The 25 mm bore, 25 mm stroke unit is rolled together from a stainless tube and aluminium-alloy covers - no tie rods to work loose - and runs double acting with a variable air cushion at each end that you dial in with needle screws.
Force output at 0.5 MPa is 245.3 N on extension and 206.1 N on retraction, rising to 343.4 N and 288.5 N at 0.7 MPa. Planning around 147 N of usable thrust at 0.5 MPa keeps the mechanism inside a sensible margin. The U flat-end back cover suits fixed mounting; add FA flange, LB foot or SDB pivot hardware where the frame demands it. The piston magnet ships standard, so CMSG / DMSG / EMSG switches bolt on for position feedback.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X25SU Is Used
Carton push-off beside a belt
Clamped to the frame by its flat ends, the body drives a paddle that tips cartons onto a takeaway belt; 245.3 N of push at 0.5 MPa handles loaded boxes.
Hold-down on a welding jig
Swings a clamp shoe onto tube stock before tack welds; working near the 147 N figure keeps clamp force realistic and repeatable.
Pallet stop on a transfer car
Stops incoming pallets at the pick face; cushioning at both ends absorbs the impact of a rolling load shift after shift.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X25SU the Right Cylinder?
Between the 20 mm bore (157.0 N push at 0.5 MPa) and the 32 mm bore (402.2 N), this 25 mm unit covers the mid-range where most mini fixtures land. Note it holds nothing on air loss - the rod settles wherever the load takes it once the valve centres - so a pilot check valve or rod lock belongs in circuits that must trap position.
Stroke stays standard up to 500 mm on this bore, and longer travels are made to order. Choose G or NPT thread options if the plant does not run PT; the rod thread is M10x1.25.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
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 On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAC Stainless Steel Mini Air Cylinder MAC25X25SU FAQ
Push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N and pull 288.5 N at 0.7 MPa; theoretical peak 50.0 kgf at 1.0 MPa. The 10 mm rod carries an M10x1.25 male thread and this bore breathes through 1/8" ports.
The U back cover presents flat ends so simple L-brackets, machine plates, FA flanges or LB feet bolt straight against them without adapters. Operating window is 0.15-1.0 MPa (22-145 psi), -20 to +70 C, at 30-800 mm/s.
