Airtac MAC Stainless Steel Mini Air Cylinder MAC20X150SUFA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X150SUFA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 150mm stroke, 1/8" 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 MAC20X150SUFA
With 150 mm of travel in a 20 mm double-acting bore, this MAC pushes 157.0 N at 0.5 MPa and 219.8 N at 0.7 MPa, returning with 131.9 N at the lower pressure. Needle screws give a variable air cushion at both ends, so a rod moving anywhere in the 30-800 mm/s range decelerates gently instead of hammering the covers. For sizing, treat about 94 N as the usable force at 0.5 MPa - roughly an 8 kg vertical lift with a 2:1 margin.
The body is a riveted stainless-steel round barrel with aluminium covers and a hard-chrome plated 8 mm rod, an edge over painted minis in damp, food-wash or outdoor spots. The FA flange bolts the barrel rigidly while the U flat-end back cover presents a clean fixing face, and the standard built-in magnet lets CMSG, DMSG or EMSG switches sit anywhere along the stroke.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MAC20X150SUFA Is Used
SMT pallet indexing
Mounted by its FA flange along a transfer rail, it nudges loaded PCB pallets from the printer to the placement head on an SMT line.
Case flap folding
The 150 mm reach folds tall top flaps over on small shipping cartons at a case packer infeed, with the cushions softening every fold.
Bench fixture lift
Standing upright on its flange, it raises drilling jigs or check fixtures of up to about 8 kg on a small machine bench.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X150SUFA the Right Cylinder?
If 157 N is more than the job needs, a 16 mm bore MAC delivers 100.5 N at 0.5 MPa; if the load grows, a 25 mm bore reaches 245.3 N. Air comes in through the 1/8 inch port at 0.15-1.0 MPa (22-145 psi). Note that the rod drifts freely whenever the valve centres or supply pressure fails - fit a rod lock or pilot check valve where the load must stay put. The flange and flat rear face hold the cylinder square over the long 150 mm stroke, but keep side loads off the 8 mm rod or guide them externally; the standard magnet pairs with CMSG, DMSG or EMSG switches.
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 MAC20X150SUFA FAQ
At 0.5 MPa it pushes 157.0 N and pulls 131.9 N; at 0.7 MPa those figures climb to 219.8 N and 184.7 N. The 20 mm bore is theoretically capable of about 32 kgf at 1.0 MPa.
Yes. The piston magnet comes standard on every MAC, so CMSG, DMSG or EMSG switches clip straight onto the stainless barrel and signal end or mid positions without a special-order piston.
