Airtac MAC Stainless Steel Mini Air Cylinder MAC50X25SCAH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X25SCAH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 25mm stroke, 1/4" 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 MAC50X25SCAH
Built on AirTAC's round riveted-barrel MA platform, MAC50X25SCAH is a double-acting mini cylinder with a 50 mm bore and 25 mm stroke. A stainless-steel barrel, a 20 um hard-chrome plated carbon-steel rod and rolled aluminium covers give it a sealed body that shrugs off washdown and damp plant air far better than painted minis. At 0.5 MPa it pushes 981 N and pulls 881 N; at 0.7 MPa the push climbs to 1374 N. A variable air cushion at both ends lets you tune the 25 mm stop so faster cycles or heavier loads land without hammering the covers.
For real sizing, count on roughly 589 N of usable work force at 0.5 MPa, which is about 60% of the rating. The full 981 N equates to lifting about 100 kg vertically; halve that to around 50 kg if you want a 2:1 margin. The CA pivot back cover in this version accepts a clevis or pin joint directly, and the built-in magnet means CMSG, DMSG or EMSG switches clip 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MAC50X25SCAH Is Used
Bottling line capping heads
The 981 N push at 0.5 MPa presses caps home over 25 mm of travel, while the CA pivot cover absorbs slight head misalignment on rotary cappers.
Bench staking press
With about 589 N of working force available at 0.5 MPa, this bore stakes rivets and press-fits bushings in sheet-metal brackets without a full-size press.
Fixture lift-and-locate pins
A weld fixture on a machining line uses the short stroke to raise locating pins; the variable cushion stops the 16 mm rod gently at top of travel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X25SCAH the Right Cylinder?
At 50 mm bore this sits a class above the 40 mm MAC, which pushes 628 N at 0.5 MPa; if you need more than 981 N, step to the 63 mm bore at 1558 N. Remember the cylinder does not lock its position: when air drops or the valve centres, the rod drifts, so fit a pilot check valve or rod lock for held loads. Port size is 1/4" on this bore, the rod is 16 mm with an M14x1.5 male thread, and standard stroke tops out at 500 mm, so 25 mm is comfortably in range. Pair the CA pivot cover with an I or Y rod knuckle for pivoting links, or add an FA flange or LB foot for fixed mounting.
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 MAC50X25SCAH FAQ
Push is 981 N and pull 881 N at 0.5 MPa; at 0.7 MPa push rises to 1374 N and pull to 1233 N. Theoretical maximum is 200 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s, with a 1/4" port, a 16 mm rod and M14x1.5 male thread.
The CA cover carries a pivot point, so the cylinder can swing with a clevis or pin-jointed load without bolt-on adapter brackets. If the machine needs a fixed mount instead, FA flange, LB foot or SDB pivot brackets fit the same barrel, and every unit ships with the magnet already built in for CMSG, DMSG and EMSG switches.
