Airtac MAC Stainless Steel Mini Air Cylinder MAC50X125SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X125SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 125mm 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 MAC50X125SCA
A double acting cushioned mini cylinder with a 50 mm bore, the MAC50X125SCA takes air on both sides of the piston and cushions the last of the travel at each end with variable needle screws. Its 0.5 MPa push of 981 N places it in the mid-heavy class, paired with an 881 N pull; step the supply to 0.7 MPa and push climbs to 1374 N against a theoretical 200 kgf peak.
The rolling-packed body - a stainless barrel riveted between aluminium covers - shrugs off washdown and damp shop air that peels paint off lesser steel minis. Sized off the 981 N rating, keep real workloads near 588 N for a comfortable margin; the same force equals roughly 100 kg of vertical pull, so halved it lifts about 50 kg with headroom. The CA pivot back cover swings on toggle linkages, and the built-in magnet is standard, so CMSG or EMSG switches mount without special ordering.

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 MAC50X125SCA Is Used
Press-fit assembly cell
A 981 N push at 0.5 MPa seats bearings into aluminium housings on an automotive sub-assembly line, with the CA pivot eye swinging on a toggle clamp linkage.
Carton flap tucker
The cushioned 125 mm stroke folds heavy flap stacks on a case packer, dialling out the stop so cartons never jam at the fold.
Gate diverter on sortation
Pushes parcels across a divert gate at up to 800 mm/s; the standard magnet plus EMSG switch confirms each stroke end for the PLC.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X125SCA the Right Cylinder?
Between the 40 mm bore (628 N push at 0.5 MPa) and the 63 mm bore (1558 N push at 0.5 MPa), this 50 mm cylinder covers mid-range pressing, clamping and lifting. Remember the plain MAC drifts when air drops - it holds no position once the valve centres - so add a rod lock or pilot check valve where a load must stay put. FA flange, LB foot and SDB pivot brackets, plus I and Y rod knuckles, pair with the CA pivot cover, and ports are 1/4 on this bore.
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 MAC50X125SCA FAQ
At 0.5 MPa it pushes 981 N and pulls 881 N; at 0.7 MPa push is 1374 N with pull at 1233 N. Theoretical maximum is 200 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
It gives the cylinder a pivot eye at the rear, so swinging linkages, toggle clamps and lever arms connect without extra brackets. Alternatives are the CM round-end and U flat-end covers; FA flange, LB foot and SDB pivot brackets bolt on when the mount needs more.
