Airtac MAC Stainless Steel Mini Air Cylinder MAC50X260SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X260SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 260mm 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 MAC50X260SU
Where a 25 mm stroke cannot reach, the MAC50X260SU covers 260 mm - still a standard length, well inside the 500 mm limit for the 50 mm bore. It is double-acting with a variable air cushion at both ends, pushing 981 N and pulling 881 N at 0.5 MPa, or 1374 N at 0.7 MPa, so long moves can run briskly and still land quietly. Over that longer travel the riveted stainless barrel and 20 um hard-chrome plated rod matter more: the bore resists the scoring and corrosion that would seize a painted mini partway through its life.
Plan the job around about 589 N of practical 0.5 MPa force, or roughly 50 kg of vertical lift once a 2:1 margin is applied to the 100 kg theoretical figure. Because the 16 mm rod is exposed for 260 mm, guide the load externally - side load on a long rod is the main cause of premature seal wear in any mini cylinder. The U flat-end cover, standard magnet and CMSG / DMSG / EMSG switch compatibility round out the package.

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 MAC50X260SU Is Used
Paint-line part elevator
A dip-tank elevator on a small paint line lifts jigs of roughly 40 kg per cycle; the 100 kg-class push covers it with room to spare and the cushions settle the load at the bottom.
CNC guard door actuator
Machine-shop cells use the 260 mm stroke to slide CNC guard doors fully open, the stainless barrel and chrome rod shrugging off constant coolant mist.
Layer-forming pusher
A palletising cell squares carton layers at the end of a roller conveyor, drawing on about 589 N of working force for firm positive pushes.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X260SU the Right Cylinder?
Compared sideways: the 40 mm bore moves 628 N at 0.5 MPa within the same family architecture, and the 63 mm bore raises that to 1558 N if your 260 mm move needs more muscle. This cylinder cannot park a load - with a centred valve or lost air the rod coasts to wherever physics takes it - so a pilot check valve or rod lock belongs in the circuit for held strokes. An FA flange or LB foot at both ends keeps the long body aligned far better than a single cantilevered fixing; the 1/4" port, 16 mm rod and M14x1.5 thread are standard at bore 50.
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 MAC50X260SU FAQ
Push 981 N and pull 881 N at 0.5 MPa; push 1374 N and pull 1233 N at 0.7 MPa; 200 kgf theoretical maximum at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s over the 260 mm stroke, with a 1/4" port and M14x1.5 rod thread on a 16 mm rod.
Yes - guide the load on linear rails or a slide so side loads stay off the 16 mm rod, and use FA flange or LB foot mounts to keep the long barrel straight. If the application must hold position mid-stroke, add a rod lock or pilot check valve, because the cylinder itself drifts when air is removed.
