Airtac MAC Stainless Steel Mini Air Cylinder MAC50X75SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X75SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 75mm 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 MAC50X75SU
Stop shock under control: with a variable air cushion at both ends, the MAC50X75SU tames end-of-travel impact so you can move heavy loads faster without hammering the covers. The U flat-end back cover presents a clean flat face for direct fixed mounting, and the stainless round barrel with its hard-chrome plated 16 mm rod shrugs off washdown and outdoor weather. Double acting, 0.15-1.0 MPa (22-145 psi) supply, 30-800 mm/s speed.
At 0.5 MPa the 50 mm bore generates 981 N pushing and 881 N pulling; 0.7 MPa raises push to 1374 N, and the theoretical ceiling at 1.0 MPa is 200 kgf. Hanging weight from the rod, expect roughly 100 kg of vertical capability - half that, about 50 kg, if you demand a 2:1 safety margin on real part weights. The cushion needs airing on commissioning: open the needle screws fully, then close gradually. A magnet comes built in, so CMSG, DMSG or EMSG switches signal position with zero 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 MAC50X75SU Is Used
Slide clamp on a CNC fixture plate
Flat U cover bolts straight to the plate; 981 N clamps the aluminium blank through roughing cuts.
Roll ejector on an extrusion table
The cushion eases hot profiles to a gentle stop as the 75 mm stroke kicks finished lengths off the run-out.
Press head on a bench crimper
Working near 589 N, the cylinder crimps terminals all shift while the chrome rod resists shop-floor humidity.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X75SU the Right Cylinder?
The 40 mm bore offers 628 N at 0.5 MPa for lighter work and the 63 mm bore 1558 N for heavier; either swaps into the same pattern of FA flange, LB foot and SDB body mounting. With the U flat-end cover the body fixes directly to a flat machine surface where no pivot is wanted. Keep in mind the rod settles the moment air is lost or the valve returns to centre - nothing in a plain MAC locks it - so specify a rod lock or pilot check valve for suspended or held loads.
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 MAC50X75SU FAQ
Push 981 N and pull 881 N at 0.5 MPa; push 1374 N and pull 1233 N at 0.7 MPa; theoretical maximum 200 kgf at 1.0 MPa. The air port is 1/4" PT with G or NPT options, rod thread M14x1.5, and the 75 mm stroke is a standard length within this bore's 500 mm limit.
It provides a flat rear face for direct bolting where no pivot is needed, complementing the FA flange, LB foot and SDB body mounts. Whichever cover you pick, the magnet remains standard, so CMSG, DMSG or EMSG position switches attach to the barrel unchanged.
