Airtac MAC Stainless Steel Mini Air Cylinder MAC25X50SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X50SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 50mm 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 MAC25X50SCA
Short, punchy and corrosion-resistant: the MAC25X50SCA is a double-acting round-body mini cylinder whose stainless-steel barrel and hard-chrome plated rod stand up to washdown areas that ruin painted minis. Its 25 mm bore generates 245.3 N of push and 206.1 N of pull at 0.5 MPa, rising to 343.4 N at 0.7 MPa, while variable air cushions at both ends soften the last millimetres of each 50 mm stroke. CA pivot eyes on the back cover let the body follow arc motion without extra hardware.
Size the job at about 147 N of honest working force at 0.5 MPa. For vertical duty, 245.3 N equates to roughly 25 kgf, so with a 2:1 margin it hoists about 12 kg. The magnet is included as standard, so CMSG, DMSG or EMSG reed switches snap on for end-of-stroke signalling.

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 MAC25X50SCA Is Used
Welding fixture clamp
Clamps sheet-metal brackets on a welding jig; the CA pivot eye follows the clamp arm's arc through the 50 mm stroke.
Mould part ejector
Knocks small moulded parts clear of the cavity at end of cycle, with the cushion preventing the ejector plate from slamming home.
Small-parcel flipper arm
Tips lightweight parcels onto a sortation spur; the standard magnet and a CMSG switch confirm each flip without a special piston order.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X50SCA the Right Cylinder?
Downsize to a bore 20 (157 N push at 0.5 MPa) for light clamping, or step up to a bore 32 (402.2 N) when cycles get heavy; the 25 mm class covers most compact tooling. With only 50 mm of stroke, side loads are rarely an issue, but keep thrust axial all the same. Mind that a standard MAC holds nothing on air loss - the rod drifts under load - so add a rod lock or pilot check valve where clamping pressure must persist.
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 MAC25X50SCA FAQ
Full set: 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push at 0.7 MPa, and 50 kgf theoretical maximum force at 1.0 MPa. It operates on 0.15-1.0 MPa (22-145 psi), takes 1/8" ports, uses an M10x1.25 rod thread and cycles at 30-800 mm/s.
Both ends carry a variable cushion with needle screws. Open them fully before the first cycle, then close gradually until end-of-stroke knock fades; on a 50 mm stroke that keeps fast clamping quiet and protects the aluminium-alloy covers.
