Airtac MAC Stainless Steel Mini Air Cylinder MAC50X50SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X50SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 50mm 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 MAC50X50SU
Flat, flush and fast to fit - the U back cover on this MAC50X50SU bolts straight to a plate, hiding the 50 mm bore cylinder behind the machine frame. Force output is 981 N push and 881 N pull at 0.5 MPa, with 1374 N of push available at 0.7 MPa in a double-acting, twin-cushion design.
The stainless round barrel with rolled-on covers and a 20 um hard-chrome plated rod stands up to washdown and outdoor spray. Speed runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) air, and the fitted magnet accepts CMSG / DMSG / EMSG switches anywhere along the barrel. For sizing, use about 589 N of practical force at 0.5 MPa - equivalent to lifting about 50 kg vertically at a 2:1 margin.

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 MAC50X50SU Is Used
CNC fixture clamp
Clamps aluminium plates to a milling fixture; 981 N at 0.5 MPa and a flat-end U cover that bolts flush behind the fixture plate.
Assembly vise assist
Drives the moving jaw of a light pneumatic vise on a wiring bench; the 50 mm stroke matches jaw travel and 589 N of practical force grips without crushing.
Index dial lock pin
Pushes a lock pin down into an indexing dial table; vertical use is exactly where the roughly 50 kg lift margin at 2:1 becomes the sizing check.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X50SU the Right Cylinder?
If 628 N at 0.5 MPa from a 40 mm bore covers the job, go smaller; if not, the 63 mm bore offers 1558 N. The flat-end U back cover bolts flush to a plate with no bracket, and FA flange / LB foot options exist for frame mounting. This MAC does not lock itself in place: a centred valve or lost air lets the rod wander, so a rod lock or pilot check valve is the answer for held loads. The standard magnet means CMSG / DMSG / EMSG switches mount anywhere on the barrel.
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 MAC50X50SU FAQ
Expect 981 N push and 881 N pull at 0.5 MPa, 1374 N push and 1233 N pull at 0.7 MPa, and 200 kgf theoretical maximum at 1.0 MPa from the 50 mm double-acting bore. Stroke is 50 mm, ports are 1/4", the rod is 16 mm with an M14x1.5 thread, and the cushion is variable at both ends.
Yes - the magnet is part of the standard build, not an option, so CMSG / DMSG / EMSG reed or electronic switches clamp onto the stainless barrel to flag extend and retract. Combined with the flat-end U cover, you get a compact fixed-mount cylinder that signals position without extra plumbing.
