Airtac MAC Stainless Steel Mini Air Cylinder MAC25X700SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X700SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 700mm 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 MAC25X700SCM
For machines that fit their own rod end, the MAC25X700SCM pairs a 25 mm bore and 700 mm made-to-order stroke with a CM round-end back cover, leaving a clean boss for a weld-on or thread-on custom eye. Output is classic 25 mm MAC: 245 N push at 0.5 MPa, 343 N at 0.7 MPa, with the rod retracted by air at 206 N and a variable cushion at both ends.
Read as a lift rating, 245 N at 0.5 MPa equals about 25 kg vertical; halving for a 2:1 margin leaves 12 kg, a handy check when sizing a hopper gate or take-up weight. Belt take-up towers, long gates and sliding hoppers all benefit from the stainless barrel, which stays smooth where washdown or outdoor moisture would roughen a painted tube, and the fitted magnet pairs with CMSG, DMSG or EMSG switches out of the box.

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 MAC25X700SCM Is Used
Belt take-up on a long incline chip conveyor
700 mm of take-up travel absorbs slack as the belt wears; 147 N of working push at 0.5 MPa suits light tensioning with headroom for friction.
Hopper slide on a seed-coating drum
The stainless barrel and chrome rod handle dusty, slightly damp coating powder, while the cushioned ends stop the slide cracking home at stroke end.
Adjustable outfeed stop on a timber rip saw
The round-end cover takes a shop-made eye, letting the saw builder hang their own adjustable stop linkage off the 700 mm travel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X700SCM the Right Cylinder?
Downsize to 20 mm (157 N push at 0.5 MPa) for gate duty under 150 N; upscale to 32 mm (402 N push at 0.5 MPa) where belt tension or grit adds drag. On a 700 mm stroke, keep the load guided externally so the slender rod never sees side force. The CM round end also accepts SDB pivot or LB foot brackets if you later decide to mount the barrel itself. If the machine must hold the gate open through a power dip, remember this double acting cylinder drifts when air is removed; a pilot check valve is the usual fix.
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 MAC25X700SCM FAQ
Expect 245 N push and 206 N pull at 0.5 MPa, 343 N push and 289 N pull at 0.7 MPa, and 50 kgf theoretical maximum at 1.0 MPa from the 25 mm bore. Pressure spans 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof; speed spans 30-800 mm/s. Ports are 1/8 inch, and the 700 mm stroke is made to order, beyond the 500 mm standard maximum.
It leaves a plain cylindrical boss instead of a machined eye, so machine builders can fit a weld-on or thread-on rod eye of their own design. Everything else is unchanged: riveted stainless round body, variable air cushion at both ends, and the standard piston magnet that works with CMSG, DMSG and EMSG switches.
