Airtac MAC Stainless Steel Mini Air Cylinder MAC50X160SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X160SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 160mm 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 MAC50X160SU
Flat where others are round, the MAC50X160SU's U back cover sits flush against a machine plate, so mounting costs zero adapter blocks. Inside is the same proven recipe: stainless barrel, hard-chrome plated 16 mm rod, aluminium covers rolled tight. Double acting and cushioned at both ends, the 50 mm bore makes 981 N of push and 881 N of pull at 0.5 MPa (72 psi), rising to 1374 N at 0.7 MPa (102 psi) over a 160 mm stroke.
Vertical jobs are where this bore shines: 981 N at 0.5 MPa (72 psi) matches about 100 kg of dead lift, so halving for margin leaves roughly 50 kg - a counterbalanced washer lid or hopper gate fits comfortably. On first start, back both cushion screws off, then close them step by step as speed climbs anywhere in the 30-800 mm/s band. The magnet comes fitted from the AirTAC line, letting CMSG, DMSG or EMSG switches report position from day one.

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 MAC50X160SU Is Used
Seed hopper slide gate
Sliding a 45 kg gate plate open under a seed hopper: 589 N of usable force at 0.5 MPa (72 psi) moves it cleanly, and the flat U cover bolts the cylinder directly to the hopper skirt.
Parts washer lid lift
Raising the counterbalanced lid of an industrial parts washer, about 50 kg with a 2:1 margin: the stainless barrel laughs at detergent mist, and the end cushions set the lid down softly.
Roller line stopper
Deploying a stop blade under a gravity roller conveyor: 981 N at 0.5 MPa (72 psi) halts incoming crates, and the cushions keep the blade from bouncing back through its 160 mm travel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X160SU the Right Cylinder?
Lighter than needed? The 40 mm bore returns 628 N at 0.5 MPa (72 psi). Heavier clamping calls for 63 mm at 1558 N. This is a plain double-acting unit: centring the valve dumps the air and the rod follows gravity or spring-back in the load, so fit a pilot check valve or rod lock for anything that must stay put. The U flat-end plus an FA flange or LB foot bracket makes rigid frames simple, CMSG, DMSG or EMSG switches mount straight onto the built-in magnet, and the 1/4 inch ports sustain flow over longer supply runs.
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 MAC50X160SU FAQ
Push at 0.5 MPa (72 psi) is 981 N, pull is 881 N; at 0.7 MPa (102 psi) push is 1374 N and pull 1233 N; theoretical peak at 1.0 MPa (145 psi) is 200 kgf. Rod 16 mm with M14x1.5 thread, 1/4 inch ports, 160 mm stroke, operating pressure 0.15-1.0 MPa (22-145 psi).
The rolled stainless tube and hard-chrome plated rod shrug off condensation, washdown mist and mild chemicals that blister coated aluminium bodies, and the riveted construction keeps its seal with no tie rods to re-torque - useful in food plants, outdoor equipment and wet machining cells.
