Airtac MAC Stainless Steel Mini Air Cylinder MAC40X190SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X190SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 190mm 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 MAC40X190SCA
Lift, press or divert with 190 mm of travel and 628 N behind it - at 0.5 MPa (72.5 psi) this 40 mm bore delivers 628 N out and 528 N back, climbing to 880 N at 0.7 MPa. Being double acting, air does the work in both directions, and the variable air cushion at each end is dialled in with needle screws so heavier loads stop softly at full speed.
Build quality is where the MAC range earns its keep: a stainless round barrel riveted to aluminium covers, plus a hard-chrome plated rod, resists the washdown mist and outdoor damp that corrode painted minis. Budget for about 377 N of genuine working force at 0.5 MPa rather than the full 628 N. Every unit carries a standard piston magnet, so CMSG, DMSG and EMSG switches fit without special ordering.

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 MAC40X190SCA Is Used
Pallet jig lift
Raises a locating jig with about 32 kg of vertical lift capability, using the 64 kgf push rating at 0.5 MPa with a 2:1 margin.
Oven damper slide
Slides a baking-oven damper open and shut; the stainless body stands up to the humid washdown regime of a food plant.
Lane diverter
Swings a diverter arm on the CA clevis pin between two conveyor lanes, with a DMSG switch confirming each side.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X190SCA the Right Cylinder?
Sizing by 0.5 MPa push: 32 mm gives 402 N, this bore 628 N, and 50 mm 981 N - choose the 40 when loads sit near 35 kg. If the load must hold when air is lost, note that the rod coasts freely once pressure drops; a pilot check valve or rod lock is the fix. The CA pivot back cover accepts a clevis pin for swinging motion, while FA flange, LB foot or SDB pivot brackets handle fixed mounts. On a 190 mm stroke, avoid side loads on the 16 mm rod or support the tooling with external guides.
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 MAC40X190SCA FAQ
40 mm bore, 190 mm stroke, 16 mm rod, 1/8 in port, M12x1.25 rod thread. Forces: 628 N push and 528 N pull at 0.5 MPa; 880 N push and 739 N pull at 0.7 MPa; 128.1 kgf theoretical maximum at 1.0 MPa. Temperature span is -20 to +70 C.
Yes, and at no option cost - the piston magnet is standard, so CMSG, DMSG or EMSG switches clip onto the barrel. The cylinder runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um.
