Airtac MAC Stainless Steel Mini Air Cylinder MAC40X200SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X200SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 200mm 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 MAC40X200SU
A flat-end fixing and 200 mm of cushioned travel make the MAC40X200SU the straightforward pick when a machine plate simply bolts flat against the cylinder nose. This 40 mm double-acting mini from AirTAC delivers 628 N of push and 528 N of pull at 0.5 MPa (72.5 psi), with a variable air cushion at both ends to absorb the landing.
Inside is a riveted stainless-steel barrel and a 16 mm hard-chrome carbon-steel rod, so outdoor gates and humid workshops do not eat the body the way they would a painted-aluminium mini. Plan the load with the derated figure: three-fifths of 628 N is about 377 N of honest working force at 0.5 MPa, or a 32 kg vertical lift keeping a 2:1 factor. The built-in magnet feeds CMSG, DMSG or EMSG switches with no wiring changes to the cylinder itself.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MAC40X200SU Is Used
Silo vent dust-cap lift
Raising a hinged dust cap on a farm silo vent, where 377 N of derated force swings the cap and the cushion stops it slamming open.
Pilot-plant mixer head press
Lowering a mixing head into a 20 L vessel on a pilot-plant bench through the full 200 mm, with 628 N of downforce available when needed.
Timber-shop hold-down roller
Keeping a hold-down roller pressed on a saw table, where the stainless barrel copes with damp timber-shop air that corrodes painted bodies.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X200SU the Right Cylinder?
Benchmarks either side: the 25 mm bore of this family pushes 245 N at 0.5 MPa and the 63 mm bore reaches 1558 N, so 40 mm sits comfortably in the middle for mid-weight pushes. Porting is 1/8 inch on this bore (PT standard, G or NPT to order). Because the MAC is not a holding cylinder - the rod drifts as soon as supply drops - add a rod lock or pilot check where the 200 mm stroke must stop mid-travel. On a stroke this long, guide the load externally so bending never reaches the rod; the U cover plus an LB foot or FA flange handles the base fixing.
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 MAC40X200SU FAQ
At 0.5 MPa: 628.3 N push and 527.8 N pull. At 0.7 MPa: 879.6 N push and 738.9 N pull. The ceiling is 128.1 kgf theoretical at 1.0 MPa, with supply running 0.15-1.0 MPa (22-145 psi).
It presents a direct flat bolting face against machine plates, so no pivot or clevis hardware is needed. If the layout changes, FA flange, LB foot or SDB pivot brackets still bolt on, and the cushion needle screws let you tune the landing at either end.
