Airtac MAC Stainless Steel Mini Air Cylinder MAC40X700SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X700SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 700mm 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 MAC40X700SCA
At a 40 mm bore the MAC40X700SCA delivers 628.3 N of push and 527.8 N of pull at 0.5 MPa, rising to 879.6 N at 0.7 MPa - double acting, with a variable air cushion at both ends. The 700 mm stroke sits beyond the 500 mm catalogue maximum for this bore, so AirTAC builds it to order. A stainless round barrel rolled onto aluminium covers, with a 20 um hard-chrome plate on the 16 mm rod, shrugs off washdown and damp plant air where painted minis corrode.
For real-world sizing, plan on about 377 N of dependable working push at 0.5 MPa - enough to lift around 64 kg vertically, or 32 kg if you keep a 2:1 reserve. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clip onto the barrel without a special piston, and the cushion needle screws open gradually on first run so 30-800 mm/s travel never hammers the covers.

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 MAC40X700SCA Is Used
Cartoner gate lift
Raising a 30 kg hold-down gate on a cartoning machine, using the conservative 32 kg vertical lift figure with a 2:1 margin, while the end cushion settles the gate without clatter.
Pallet queue pusher
A long-stroke pusher indexing pallets along a 700 mm transfer lane; 628 N at 0.5 MPa slides loaded skids on low-friction rails at up to 800 mm/s.
Rinsed-down food line actuator
Driving chutes and diverters in a washdown zone of a dairy line, where the stainless barrel and chrome rod tolerate daily hose-down better than painted mini bodies.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X700SCA the Right Cylinder?
Bore 40 sits between the 25 mm MAC frame (245.3 N push at 0.5 MPa) and the 50 mm frame (981.3 N) - step down for lighter clamping, up if 879.6 N at 0.7 MPa feels marginal. Remember the rod drifts freely whenever air is lost or the valve centres; add a rod lock or pilot check valve if the load must stay parked. The CA pivot back cover teams naturally with SDB pivot brackets or I and Y rod knuckles, while FA flange and LB foot mounts cover fixed installations. With 700 mm of stroke, guide the load externally to keep side forces off the 16 mm rod; confirm exact rod-bending limits from the datasheet.
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 MAC40X700SCA FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa push rises to 879.6 N and pull to 738.9 N, with a theoretical peak of 128.1 kgf at 1.0 MPa. Ports are 1/8", the rod is 16 mm with an M12x1.25 thread, pressure spans 0.15-1.0 MPa (22-145 psi), and speed runs 30-800 mm/s.
Back both needle screws fully off before start-up, then open them gradually until end-of-stroke motion is smooth. The cushion is variable at each end, so you can tune it per direction as load or speed changes.
