Airtac MAC Stainless Steel Mini Air Cylinder MAC20X65SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X65SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 65mm 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 MAC20X65SU
Flat against the machine plate is where the U-ended MAC20X65SU works best: the 65 mm stroke, 20 mm bore barrel bolts down without pivot hardware and delivers 157 N forward, 131.9 N back at 0.5 MPa (219.8 N and 184.7 N at 0.7 MPa). Air cushions at both ends are adjustable, so heavier loads arrive softly even at the top of the 30-800 mm/s speed range.
Its stainless round body and hard-chrome plated rod cope with splashes and outdoor damp that would corrode painted mini cylinders, while the riveted aluminium covers keep the pack light. The magnet is included as standard for CMSG, DMSG and EMSG switches, and the practical work rating works out near 94 N at 0.5 MPa - call it an 8 kg vertical lift 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 (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 MAC20X65SU Is Used
Bench press fixture
Light staking of nylon spacers in a bench fixture; 94 N of usable force is plenty for plastics and the cushion removes the bottom-out bang.
Lane divider push
Switching product between two lanes on a food-line conveyor, where washdown splashes make the stainless barrel the practical choice.
Ejector lift plate
Lifting a small stack of blister packs to an outfeed conveyor; about 8 kg of vertical capacity with margin matches a loaded stack.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X65SU the Right Cylinder?
A 16 mm bore saves air below 100.5 N at 0.5 MPa; a 25 mm bore starts at 245.3 N for heavier clamps. For swing motion order the CA pivot or SDB bracket variant instead of this fixed U end. Bear in mind the rod drifts whenever supply pressure is lost, so hold loads with a rod lock or pilot check valve rather than trusting the cushion.
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 MAC20X65SU FAQ
157 N push and 131.9 N pull at 0.5 MPa; 219.8 N push and 184.7 N pull at 0.7 MPa; 32 kgf theoretical peak at 1.0 MPa. Keep continuous duty near 94 N. It runs on a 0.15-1.0 MPa (22-145 psi) supply, ports are 1/8" PT, the rod is 8 mm with an M8x1.25 thread, and 65 mm is a standard stroke.
The U back cover presents a flat face for direct bolting to a plate. If you later need pivoting or footed mounting, FA flange, LB foot and SDB pivot brackets fit the same barrel, and I or Y rod knuckles suit the 8 mm male thread. The magnet is already built in for CMSG, DMSG and EMSG switches.
