Airtac MAC Stainless Steel Mini Air Cylinder MAC25X35SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X35SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 35mm 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 MAC25X35SCM
Round-end CM back cover gives the MAC25X35SCM a clean, symmetrical fixing face for fixed mounts on compact fixtures. The 25 mm bore delivers 245.3 N push and 206.1 N pull at 0.5 MPa (22-145 psi), or 343.4 N at 0.7 MPa, over a 35 mm stroke with a variable air cushion at each end.
Count on around 147 N of usable push at 0.5 MPa once headroom is left, enough to raise roughly 12.5 kg vertically with a 2:1 margin. Because the stainless barrel is rolled onto aluminium covers and the rod carries 20 um of hard chrome, this mini survives splash zones and outdoor cells where painted bodies blister. The standard piston magnet pairs with CMSG, DMSG and EMSG switches.

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 MAC25X35SCM Is Used
Fixture clamp on CNC bench
The CM round-end cover fixes flush to a milling fixture plate, and about 147 N of working force holds aluminium parts against hard stops.
Sleeve press on bottling line
A 35 mm stroke seats shrink sleeves on narrow bottles, with dual cushioning absorbing the stop during 500 mm/s cycling.
Sample press in QA lab
Presses lids onto 100 ml sample cups, and the stainless body shrugs off daily IPA wipe-downs.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X35SCM the Right Cylinder?
Between the MAC20X35 at 157.0 N and the MAC32X35 at 402.2 N (both 0.5 MPa push), this 25 mm model covers mid-range clamp and push duties. The CM cover bolts flat; pivot duty needs the CA version or an SDB bracket, while FA flange or LB foot options cover other frames. Ports are 1/8 inch, rod thread M10x1.25 on a 10 mm rod. If a centred valve could let the load sag, fit a pilot check valve - this cylinder does not lock itself.
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 MAC25X35SCM FAQ
Push is 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa expect 343.4 N push and 288.5 N pull, topping out at 50 kgf theoretical at 1.0 MPa. Supply window 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
It presents a flat, symmetrical face for direct bolting into slots or fixture plates without adapter brackets. Pair it with FA flange, LB foot or SDB pivot brackets when the frame needs them; for swinging linkages, order the CA pivot version instead.
