Airtac MAC Stainless Steel Mini Air Cylinder MAC40X105SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X105SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 105mm 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 MAC40X105SCM
With a 40 mm bore pushing 628 N and pulling 528 N at 0.5 MPa, the MAC40X105SCM covers medium-duty stroking over a generous 105 mm of travel. It is double acting with a variable air cushion at both ends, so the needle screws let you dial out end-of-stroke shock and run harder or carry more without hammering the covers. Cycle speed spans 30-800 mm/s on a 0.15-1.0 MPa (22-145 psi) supply of air filtered to 40 um.
The riveted stainless round barrel and hard-chrome plated 16 mm rod laugh at damp, washdown-prone spots where painted mini cylinders start to rust, and the CM round-end back cover gives a neat fixed mounting without extra brackets. Every unit ships with a built-in magnet, so CMSG / DMSG / EMSG switches drop straight on. Theoretical output reaches about 128 kgf at 1.0 MPa; for vertical work that equates to lifting roughly 32 kg with a 2:1 margin.

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 MAC40X105SCM Is Used
Bench press ejection
Knocking formed gaskets or PCB pallets clear of a fixture - 628 N at 0.5 MPa does the job in one 105 mm push.
Diverter gate on washdown lines
The stainless barrel copes with frequent hose-down in dairy or bottling plants while the air cushion lands the gate quietly.
Lid lift on a curing oven
Raises about 32 kg vertically with a 2:1 margin; the CM round-end cover mounts directly to the linkage.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X105SCM the Right Cylinder?
Need less force? A 32 mm bore MAC pushes 402 N at 0.5 MPa; need more, the 50 mm bore reaches 981 N. Note the rod will drift if air is lost, so add a rod lock or pilot check valve when the load must stay put. The 105 mm stroke keeps rod bending modest, but guide the load externally if side forces are present. PT, G and NPT port threads are available, and FA flange, LB foot or SDB pivot brackets bolt on as the frame demands.
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 MAC40X105SCM FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N; at 0.7 MPa, 880 N push and 739 N pull. Theoretical peak is about 128 kgf at 1.0 MPa. Ports are 1/8", rod thread M12x1.25, rod diameter 16 mm, and the 105 mm stroke sits well inside the 500 mm standard limit for this bore.
Back both needle screws fully off before start-up, then close them gradually until end-of-stroke bounce stops. The variable air cushion works at both ends, letting you run up to 800 mm/s without hammering the aluminium covers.
