Airtac MAC Stainless Steel Mini Air Cylinder MAC50X140SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X140SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 140mm 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 MAC50X140SCM
A 140 mm stroke with real muscle: the MAC50X140SCM pairs the 50 mm MA bore - 981 N push and 881 N pull at 0.5 MPa, 1374 N at 0.7 MPa - with a CM round-end back cover that bolts flush against machine faces. The round stainless barrel is riveted to the aluminium covers, and the hard-chrome plated rod keeps its 20 um finish through humid or mildly corrosive air that would corrode painted minis.
Leave about 589 N of that 0.5 MPa rating for actual work and the cylinder will run cool and last; in lifting terms it can raise roughly 100 kg in theory, or a 50 kg part with a sensible 2:1 margin. The variable air cushion at each end is tuned with needle screws to absorb heavier loads at speed, the built-in magnet feeds CMSG / DMSG / EMSG switches as standard, and 1/4" ports plus an M14x1.5 rod thread make plumbing simple. It runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi).

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 MAC50X140SCM Is Used
Milling fixture clamp
Clamping aluminium housings on a small machining centre: about 589 N of working clamp force holds parts firm, and the CM round-end cover bolts flat to the fixture plate.
Rotary index push
Advancing a four-station dial table one pitch per cycle, with the built-in magnet triggering CMSG switches to confirm each index position.
Lug crimp bench
Crimping cable lugs on a wire-harness bench - 981 N at 0.5 MPa forms the barrel, and the variable cushion keeps the crimp from bouncing.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X140SCM the Right Cylinder?
Sizing rule of thumb: the 50 mm bore turns 0.5 MPa into 981 N, the 40 mm bore 628 N, the 63 mm bore 1558 N - choose 50 mm when your working load is around 580-590 N after margin. Note that nothing locks the piston; cut the air and it moves, so fit a pilot check valve or rod lock where a clamped part must stay gripped. The CM round-end back cover mounts flush to fixed faces without brackets, or add SDB pivot, FA flange and LB foot as the frame demands. With 140 mm of stroke the 16 mm rod needs the load guided or purely axial.
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 MAC50X140SCM FAQ
Push 981 N and pull 881 N at 0.5 MPa; push 1374 N and pull 1233 N at 0.7 MPa; 200.1 kgf maximum theoretical force at 1.0 MPa. Proof pressure is 1.5 MPa (215 psi) and working range 0.15-1.0 MPa (22-145 psi), 30-800 mm/s.
No - the magnet is built into the piston as standard, so CMSG, DMSG or EMSG reed and electronic switches mount straight onto the 50 mm barrel. Every MAC ships this way; no special-order piston is needed.
