Airtac MAC Stainless Steel Mini Air Cylinder MAC50X350SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X350SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 350mm 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 MAC50X350SCA
Air feeds both ports on this cylinder, so it drives out and retracts under power - double acting with a variable air cushion at each end that you tune with the needle screws. The 50 mm bore pushes 981.3 N and pulls 880.8 N at 0.5 MPa; at 0.7 MPa the extend figure rises to 1373.8 N, and theoretical force peaks at 200.1 kgf when 1.0 MPa is applied. Rod speed spans 30-800 mm/s across a 0.15-1.0 MPa (22-145 psi) supply, with 1.5 MPa (215 psi) proof rating.
Around the 350 mm travel sits a stainless round barrel riveted to aluminium covers, with a hard-chrome plated rod that shrugs off washdown and damp plant air - a real edge over painted-steel minis in food or outdoor spots. The piston magnet comes fitted as standard, so CMSG, DMSG or EMSG switches mount straight on. For sizing, count on roughly 589 N of practical work at 0.5 MPa, enough to lift about 50 kg vertically with a 2:1 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 MAC50X350SCA Is Used
Palletizer carton push-off
A 350 mm travel slides full carton layers off a palletizing conveyor; 981 N at 0.5 MPa clears heavy stacks without straining the drive.
Waterworks sluice gate
The CA pivot cover and an SDB bracket swing the rod to raise a small sluice gate at a treatment plant, the stainless barrel coping with humid basins.
Bakery tray indexing
Rows of dough trays get pushed between oven lanes, with cushioned stops protecting fragile loads at any speed up to 800 mm/s.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X350SCA the Right Cylinder?
Below this class, the 40 mm bore pushes 628.3 N at 0.5 MPa; above it, the 63 mm bore reaches 1557.9 N - step up only if the load demands it. Keep in mind the rod sits unpowered between strokes: cut the air and the piston drifts, so fit a rod lock or pilot check valve where the load must stay put. The CA pivot back cover swings on an SDB bracket or works with FA flange and LB foot plates, while I or Y rod knuckles close the linkage end. Long strokes like 350 mm magnify side load - guide the payload externally to keep the rod straight.
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 MAC50X350SCA FAQ
At 0.5 MPa it extends with 981.3 N and retracts with 880.8 N; at 0.7 MPa extend force reaches 1373.8 N, and theoretical maximum is 200.1 kgf at 1.0 MPa. Pressure window is 0.15-1.0 MPa (22-145 psi), rod speed 30-800 mm/s, port size 1/4 in with PT threading on this code.
The magnet is built in as standard, so CMSG, DMSG and EMSG switches clip straight onto the barrel - no special-order piston and no retrofit. Sensing works anywhere along the 350 mm stroke, which is handy for confirming full extend on a long push.
