Airtac MAC Stainless Steel Mini Air Cylinder MAC50X30SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X30SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 30mm 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 MAC50X30SCM
For a fixed, flush look on tight machines, the MAC50X30SCM uses a CM round-end back cover on a 50 mm stainless round barrel. It is double acting with a variable air cushion at both stroke ends, fed through 1/4" ports at 0.15-1.0 MPa (22-145 psi). Push force at 0.5 MPa is 981 N, rising to 1374 N at 0.7 MPa; the 30-800 mm/s speed range covers gentle clamping through quick ejection.
The CM cover means the rear mount is a smooth round cap - handy where a protruding eye would snag guards or sleeves. Inside, the two-way piston seal doubles as a grease reservoir, cutting lube chores over long duty cycles. In practical terms, the 0.5 MPa push equals a 100 kg vertical-lift figure, and halving it for margin still leaves about 50 kg of lifting headroom - enough to index a loaded pallet drawer with room to spare.

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 MAC50X30SCM Is Used
Carton flap folder
Folds carton flaps on a packaging head where the round rear cap tucks neatly behind a guard shroud.
Lab mixer lid clamp
Holds mixer lids down on stainless process vessels through cleaning-in-place rinse cycles.
Press fixture kicker
Ejects finished bushings from a small press die, using 30 mm of travel at up to 1374 N.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X30SCM the Right Cylinder?
Next size up is the 63 mm bore at 1558 N push; one step down, the 40 mm bore manages 628 N at the same pressure. If the load must be held with air off, this cylinder will drift - fit a rod lock or pilot check valve instead of relying on the cushion. Foot (LB), flange (FA) and SDB pivot brackets all bolt to the body when the round rear cap is not the mounting you want. The piston magnet is standard, so CMSG / DMSG / EMSG switches read position without special parts.
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 MAC50X30SCM FAQ
At 0.5 MPa the MAC50X30SCM pushes 981 N and pulls 881 N. At 0.7 MPa those become 1374 N push and 1233 N pull, and the theoretical maximum at 1.0 MPa is 200 kgf. All figures assume clean, dry air filtered to 40 um within the 0.15-1.0 MPa (22-145 psi) operating band.
The CM round end gives a flush rear face with no protruding eye, so the cylinder slides into slots or sits behind guards where a pivot eye would foul. FA flange, LB foot and SDB pivot brackets are available if you later need a fixed mount.
