Airtac MAC Stainless Steel Mini Air Cylinder MAC25X100SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X100SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 100mm 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 MAC25X100SCM
The CM round-end back cover on this MAC25X100SCM lets the cylinder pin straight onto a pivot without extra brackets, handy on linkages and clamping arms. Inside, it is a 100 mm stroke double-acting unit with a variable air cushion at each end, built on a rolled stainless barrel with a hard-chrome rod that tolerates damp and rinsed-down areas.
Bore 25 output is 245.3 N push and 206.1 N pull at 0.5 MPa (22-145 psi), climbing to 343.4 N at 0.7 MPa. Keep continuous duty near 147 N of push and the same force will hoist roughly 12.5 kg vertically against gravity with a 2:1 margin. A magnet comes built into the piston as standard, ready for EMSG, DMSG or CMSG switch pickup.

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 MAC25X100SCM Is Used
Swing-arm stopper
Stopping a rotary swing arm on an assembly conveyor; the CM round-end cover pins into the arm clevis and 206.1 N of pull retracts it clear each cycle.
Tube press station
Pressing caps onto 25 mm dip tubes in a bottling cell; 245.3 N push at 0.5 MPa seats caps while the variable cushion prevents cap cracking.
Batch gate control
Indexing product between fill and cap stations - the standard piston magnet and CMSG switches report gate position to the PLC on every stroke.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X100SCM the Right Cylinder?
Against its neighbours: bore 20 pushes 157 N at 0.5 MPa, bore 25 reaches 245.3 N, and bore 40 jumps to 628.3 N, so choose 25 for mid-range force in tight spaces. The CM round-end cover drops onto pivot pins directly, and SDB pivot brackets or LB feet bolt on if the machine prefers them. Remember the piston moves freely when air is removed - fit a rod lock or pilot check valve where a load must stay parked. With 100 mm of travel, keep the 10 mm rod protected from side thrust.
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 MAC25X100SCM FAQ
At 0.5 MPa (22-145 psi) push is 245.3 N and pull 206.1 N; at 0.7 MPa these rise to 343.4 N and 288.5 N. The 1.0 MPa theoretical maximum is 50 kgf. Supply pressure spans 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
The rolled stainless barrel and hard-chrome carbon-steel rod resist corrosion in damp, washed or outdoor locations where painted minis rust. Note it drifts freely when air is removed, so add a rod lock or pilot check valve if the load must stay parked.
