Airtac MAC Stainless Steel Mini Air Cylinder MAC50X120SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X120SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 120mm 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 MAC50X120SCA
Built as a double acting cylinder with a variable air cushion, the MAC50X120SCA reaches 120 mm while keeping the compact round-body footprint of AirTAC's MA range. The 50 mm bore generates 981 N forward and 881 N back at 0.5 MPa through 1/4" ports, covering lift, clamp and eject duties.
A 16 mm hard-chrome rod runs in a stainless barrel with rolled aluminium covers, so washdown and condensation do not eat the body. Its vertical-lift equivalent is about 100 kgf at 0.5 MPa - halve that to roughly 50 kg and you have a two-to-one margin for lifting real parts. The CA pivot back cover, FA flange, LB foot and SDB bracket give mounting freedom, and the standard magnet suits CMSG, DMSG or EMSG switches.

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 MAC50X120SCA Is Used
Tray stack lift
Lifting a 40 kg stack of plastic trays between levels in a picking cell; about 50 kg vertical capacity at 0.5 MPa keeps a 2:1 margin.
Divert gate actuator
Swinging a divert gate across a 120 mm conveyor gap; the CA pivot mounts the cylinder to follow the gate arc without extra brackets.
Fixture lift in a machining cell
Raising a machining fixture 120 mm for part changeover, cushioned at both ends so the fixture lands soft on its stops.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X120SCA the Right Cylinder?
If 981 N overshoots the load, the 40 mm bore at 628 N saves air; if it undershoots, the 63 mm bore delivers 1558 N at 0.5 MPa. Over a 120 mm stroke, keep side loads low and guide the load externally to avoid rod bending. Position is not held on air loss - the piston will drift - so fit a rod lock or pilot check valve where the load must stay. Use the CA pivot with a clevis, or the U or CM cover for fixed faces.
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 MAC50X120SCA FAQ
At 0.5 MPa it pushes 981 N and pulls 881 N. At 0.7 MPa those figures become 1374 N push and 1233 N pull, and the theoretical maximum at 1.0 MPa is about 200 kgf. Supply 0.15-1.0 MPa (22-145 psi) of 40 um filtered air and expect speeds of 30-800 mm/s.
The CA pivot back cover on this model takes a clevis for swinging motion, while other MAC50 variants offer a U flat-end or CM round-end cover. FA flanges, LB foot brackets and SDB pivot mounts bolt on, and I and Y rod knuckles connect the tooling. All share the same 1/4" ports and M14x1.5 rod thread.
