Airtac MAC Stainless Steel Mini Air Cylinder MAC40X700SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X700SCM 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 MAC40X700SCM
A 40 mm bore pushing 628.3 N and pulling 527.8 N at 0.5 MPa - and 879.6 N at 0.7 MPa - makes the MAC40X700SCM a mid-force, long-reach actuator. It is double acting with an adjustable air cushion at each end, and the 700 mm stroke is produced to order since it passes the 500 mm standard ceiling. The CM round-end back cover gives a clean pivot point without bolt-on brackets.
Do the load maths once: count on near 377 N of usable push at 0.5 MPa, which corresponds to lifting roughly 64 kg vertically, or about 32 kg when you halve it for margin. Grease-retaining two-way piston seals keep lubrication inside the barrel through millions of cycles, and the standard magnet accepts CMSG, DMSG or EMSG reed switches out of the box.

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 MAC40X700SCM Is Used
Tote elevator platform
Driving a small lift table on an assembly spine; the theoretical 64 kg lift handles loaded totes, and the 32 kg conservative figure keeps the 2:1 margin honest.
Vision inspection riser
Lifting a camera head into position over a filling line, with DMSG switches confirming both seats while the cushion damps the arrival so the optics never jolt.
Pallet-lane stop gate
Swinging a stop gate across a gravity lane; 628 N at 0.5 MPa overcomes gate and bearing friction even in dusty warehouse air.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X700SCM the Right Cylinder?
Next sizes around this frame: 32 mm at 402.2 N push (0.5 MPa) below, 50 mm at 981.3 N above - choose the 50 mm frame if 879.6 N at 0.7 MPa leaves no headroom. Centring the valve does not park the piston; expect it to settle under load unless you fit a pilot check valve or rod lock. Mounting flexibility covers the CM round-end pivot, SDB brackets, FA flanges, LB feet and I/Y rod knuckles. Long strokes like 700 mm demand guided, well-aligned loads so the 16 mm rod sees thrust only - request the datasheet for side-load limits.
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 MAC40X700SCM FAQ
Push 628.3 N and pull 527.8 N at 0.5 MPa; push 879.6 N and pull 738.9 N at 0.7 MPa; theoretical maximum 128.1 kgf at 1.0 MPa. The 700 mm stroke is made to order, the port is 1/8", the rod is 16 mm with M12x1.25 thread, and travel spans 30-800 mm/s between 0.15-1.0 MPa (22-145 psi).
No. Every MAC ships with a built-in magnet as standard, so CMSG, DMSG and EMSG switches simply snap onto the stainless barrel at the positions you need - no special-order piston or disassembly.
