Airtac MAC Stainless Steel Mini Air Cylinder MAC40X130SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X130SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 130mm 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 MAC40X130SCM
A riveted stainless round barrel rolled onto aluminium covers, a 16 mm hard-chrome plated rod and a 40 mm bore make the MAC40X130SCM a compact pusher rated at 628 N extension and 528 N retraction at 0.5 MPa (880 N and 739 N at 0.7 MPa). It is double acting, so air drives the piston both ways, with a variable air cushion at each stroke end to soak up shock when the load arrives fast.
The CM round-end back cover presents a pivot eye that swings a linkage without bolted-on brackets. Every cylinder leaves the factory with a built-in magnet, so CMSG / DMSG / EMSG switches clip straight to the barrel for end-of-stroke signalling. Keeping 40 percent in reserve, expect about 377 N of dependable working force - the kind of push that seats bearings or clamps a welding jig through a 130 mm stroke.

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 MAC40X130SCM Is Used
Welding jig clamp
Seating clamp arms on an automotive bracket fixture, where 628 N at 0.5 MPa holds the part against locating pins through the 130 mm stroke.
Bottling rinse-table actuator
Raising and lowering a rinse manifold over bottle necks in a washdown zone, helped by the stainless barrel and hard-chromed rod.
Index stop on a rotary table
Extending a stop pin into a dial-plate notch between cycles; the air cushion softens the pick-up and the magnet signals home.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X130SCM the Right Cylinder?
Compare bores before committing: a 32 mm MAC manages 402 N at 0.5 MPa, while the next size up, 50 mm, delivers 981 N, so the 40 mm class is the sensible middle for loads between roughly 240 and 377 N of continuous effort. Ports are 1/8" (bore 20 to 40) and the male rod thread is M12x1.25.
This double-acting body will not park itself - centring the valve lets the piston drift under load - so add a rod lock or pilot check valve wherever a raised part must stay put. FA flange, LB foot and SDB pivot brackets bolt up alongside the CM back cover arrangement, and the 130 mm stroke keeps side-load modest on the 16 mm rod.
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 MAC40X130SCM FAQ
At 0.5 MPa the cylinder pushes 628 N and pulls 528 N; at 0.7 MPa it reaches 880 N out and 739 N back. The theoretical maximum at 1.0 MPa is about 128 kgf. Ports are 1/8", the rod thread is M12x1.25, pressure runs 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
The CM round-end cover carries a built-in pivot eye, so swinging levers and rocker links attach with a pin instead of extra brackets. The U flat-end alternative suits rigid bolted mounts. Both share the same stainless barrel, standard magnet and 130 mm cushioned stroke.
