Airtac MAC Stainless Steel Mini Air Cylinder MAC50X30SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X30SCA 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 MAC50X30SCA
A compact 50 mm bore mini cylinder in a riveted stainless-steel round barrel, the MAC50X30SCA runs double acting with a variable air cushion at both ends. At 0.5 MPa it pushes 981 N and pulls 881 N; at 0.7 MPa those rise to 1374 N and 1233 N, with a theoretical ceiling of 200 kgf. Its 1/4" ports take 0.15-1.0 MPa (22-145 psi) of filtered air across a 30-800 mm/s speed band.
Two details pay off in daily use. The hard-chrome plated 16 mm rod and stainless tube shrug off mild corrosion, so washdown or damp food-line air is less of a worry than with painted minis. And because the cushion screws at each end are adjustable, you can trim end-of-stroke shock and push a heavier transfer load faster without hammering the covers. Sizing-wise, the full 981 N push is the rating - plan real work around 589 N at 0.5 MPa to keep a comfortable margin.

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 MAC50X30SCA Is Used
Bottle-line pusher
A 30 mm stroke suits nudging 40 kg cartons sideways between conveyor lanes at a drink bottling plant.
Fixture clamp
Clamps aluminium jig plates on a machining fixture, with cushion screws set to ease impact at both stroke ends.
Gate latch actuator
Swings a warehouse gate latch via the rear CA pivot eye, no extra bracket hardware needed.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X30SCA the Right Cylinder?
Drop to a 40 mm bore (628 N push at 0.5 MPa) if your load sits under 400 N; move to a 63 mm bore (1558 N) when the duty cycle heats up. The CA pivot back cover takes a trunnion-style mount directly, and FA flange, LB foot or SDB pivot brackets bolt on where needed. The built-in magnet pairs with CMSG / DMSG / EMSG switches for end-of-stroke sensing. Remember a plain MAC does not hold its rod when air is cut - the piston drifts, so add a rod lock or pilot check valve if the load must stay put.
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 MAC50X30SCA FAQ
At 0.5 MPa the 50 mm bore pushes 981 N and pulls 881 N. At 0.7 MPa it is 1374 N push and 1233 N pull. The theoretical maximum at 1.0 MPa works out to 200 kgf. Pushing a real load, budget roughly 589 N at 0.5 MPa so the cylinder is not pinned at its rating.
Yes - the magnet is built into the piston as standard, so CMSG, DMSG and EMSG reed switches snap onto the barrel to signal extend or retract positions. No special-order piston or retrofit is needed.
