Airtac MAC Stainless Steel Mini Air Cylinder MAC25X10SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X10SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 10mm 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 MAC25X10SCM
Short strokes do not mean soft performance: this 10 mm travel, 25 mm bore MAC pushes 245.3 N and pulls 206.1 N at 0.5 MPa, rising to 343.4 N and 288.5 N at 0.7 MPa with about 50 kgf of theoretical force available at 1.0 MPa. It is double acting, so air both extends and retracts the rod, and a variable air cushion at each end lets you bleed off end-of-stroke shock when cycling fast between 30 and 800 mm/s.
Plan around 147 N of usable push at 0.5 MPa - the equivalent of lifting a 12 kg part vertically with a safety factor of two. The CM round rear cover gives the cylinder a rounded back end where a flat face would be in the way. Inside, the stainless rolled barrel and hard-chrome plated carbon-steel rod take mild corrosion and washdown in stride, and the built-in magnet is standard, so CMSG, DMSG or EMSG reed switches bolt on with no special piston.

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 MAC25X10SCM Is Used
Lid press on a solder-pot station
A 10 mm downstroke presses the lid home on small solder pots; 147 N of working force at 0.5 MPa is ample and the variable cushion stops the press without bounce.
Label hold-down on a flat labelling head
The round CM rear sits inside a machined saddle on the labeller frame while the 10 mm stroke presses labels onto cartons one at a time.
Tip eject on a liquid handler
Chrome-plated rod and the sealed rolled barrel shrug off the humidity around an automated pipetting deck; 245.3 N easily ejects a rack of spent pipette tips.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X10SCM the Right Cylinder?
Drop to the 20 mm bore for 157.0 N or rise to the 32 mm bore for 402.2 N at 0.5 MPa if 245.3 N is the wrong size. The bore takes 1/8" ports with an M10x1.25 male rod thread and runs 0.15-1.0 MPa (22-145 psi). Air pressure on both faces means the piston coasts free on a centred valve; a pilot check valve or rod lock holds it where the job demands. Add FA flange, LB foot or SDB pivot hardware around the CM rear, and use I or Y knuckles at the rod.
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 MAC25X10SCM FAQ
Use 245.3 N extend and 206.1 N retract at 0.5 MPa, or 343.4 N extend and 288.5 N retract at 0.7 MPa. The theoretical maximum is roughly 50 kgf at 1.0 MPa. Supply anywhere in 0.15-1.0 MPa (22-145 psi) and cycle between 30 and 800 mm/s.
Back both cushion needle screws fully out before the first cycles, then close them gradually until the end-of-stroke impact disappears. The cushion is variable at both ends on the MAC, so extend and retract can be tuned separately. Speeds up to 800 mm/s stay smooth once the needles are set.
