Airtac MAC Stainless Steel Mini Air Cylinder MAC50X250SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X250SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 250mm 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 MAC50X250SCA
Double acting with a variable air cushion at both ends, this bore 50 pivot-mount cylinder turns 0.5 MPa into 981.3 N of push and 880.8 N of pull across a 250 mm stroke. Its riveted stainless round barrel and hard-chrome carbon-steel rod (20 um plating) hold up in washdown corners of food and outdoor plants that eat through painted minis, and the CA pivot back cover swings freely on a clevis without extra brackets.
Keep real loads near 589 N at 0.5 MPa - roughly 60 percent of the push figure - which is about 50 kg lifted vertically with a 2:1 margin. The magnet is built in as standard, so CMSG, DMSG and EMSG switches mount without a special piston, and raising supply to 0.7 MPa takes push to 1373.8 N.

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 MAC50X250SCA Is Used
Conveyor diverter swing arm
Swings a pusher arm across a beverage-crate conveyor; the CA pivot follows the arc and 589 N of usable force shoves a loaded crate without jolt, thanks to the end cushion.
Weld fixture clamp arm
Pivots a clamp arm onto a car-body bracket in a robotic weld cell; 981.3 N at 0.5 MPa holds the joint while a CMSG switch confirms clamp closure.
Sluice gate tilt on a hatchery channel
Tilts a water-control gate in a fish-hatchery channel where the stainless barrel resists constant splash - a spot where painted cylinders fail fast.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X250SCA the Right Cylinder?
Sized between bore 40 (628.3 N push at 0.5 MPa) and bore 63 (1557.9 N), the 50 mm bore carries loads in the 400-600 N working band comfortably. The CA pivot eye suits clevis and linkage travel; for rigid bases pick the U flat-end or CM round-end cover, or add FA flange and LB foot mounts. Air works both directions, yet nothing brakes the piston once supply drops - park a load with a rod lock or pilot check valve. Spec it with the 1/4" port, M14x1.5 rod thread, and G or NPT if your plant plumbing needs them; 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s define the operating window.
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 MAC50X250SCA FAQ
At 0.5 MPa the cylinder pushes 981.3 N and pulls 880.8 N; at 0.7 MPa push is 1373.8 N (pull 1233.1 N), and theoretical peak is 200.1 kgf at 1.0 MPa. Bore 50 uses a 1/4" port, a 16 mm rod with M14x1.5 male thread, and the 250 mm stroke is within the 500 mm standard maximum.
The CA cover provides a rear pivot eye, so the cylinder can articulate with a clevis or SDB pivot bracket without adapters. Combined with the standard magnet it also accepts CMSG, DMSG or EMSG position switches, and the variable cushion at both ends lets you tune the swing so the arm never slams home.
