Airtac MAC Stainless Steel Mini Air Cylinder MAC20X210SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X210SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 210mm 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 MAC20X210SU
AirTAC's MAC20X210SU pairs a flat-end U back cover with a 210 mm stroke on a 20 mm bore, giving 157 N forward and 131.9 N return at 0.5 MPa (219.8 N forward at 0.7 MPa). Double acting on both strokes, it cushions variably at each end, so you can open the speed up toward 800 mm/s without hammering the covers.
A 210 mm reach on an 8 mm rod is where side loads matter: guide the load externally and the stainless barrel plus hard-chrome plated rod will keep running in humid or lightly washed areas where painted minis pit. Size around 94 N at 0.5 MPa, or a 16 kg theoretical lift derated to about 8 kg vertical, and the cylinder keeps a comfortable margin. FA flange and LB foot mounts bolt the body down, and the built-in magnet feeds position signals to CMSG, DMSG or EMSG switches.

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 MAC20X210SU Is Used
Lift assist for a parts feeder bowl
About 8 kg of vertical lift with a 2:1 margin covers small part stacks across 210 mm of rise; LB feet anchor the body to the frame.
Stripper station on a forming die
The flat-end U cover seats against the die plate; 131.9 N of return force at 0.5 MPa strips formed shells on the retraction stroke.
Tooling positioner inside a CNC cell
Guided externally for zero side load, the rod pushes fixture stops through the 210 mm reach while EMSG sensing reports mid-travel via the standard magnet.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X210SU the Right Cylinder?
Bore 16 manages only 100.5 N push at 0.5 MPa and bore 25 steps up to 245.3 N; the 20 mm class at 157 N is the middle ground for light-to-medium jigs. Long 210 mm strokes amplify misalignment, so align the load axis or add a linear guide, since an 8 mm rod tolerates little side load. The magnet is standard, so end-of-stroke sensing via CMSG / DMSG / EMSG costs no special order. Remember that air loss means drift - hold the load with a pilot check valve or rod lock, not with the cylinder itself.
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.
