Airtac MAC Stainless Steel Mini Air Cylinder MAC40X50SCAH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X50SCAH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 50mm 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 MAC40X50SCAH
Fifty millimetres of travel on a 40 mm bore makes the MAC40X50SCAH a pick for feed, eject and lift jobs a 16 or 20 mm cylinder cannot push through. Its round stainless barrel and hard-chrome plated carbon-steel rod hold up in damp workshops, and the rolled covers seat on the tube for a sealed body that stays tight over years of cycling. Note the trailing H in the code - confirm that option against the datasheet before ordering.
Double acting with a variable air cushion at both ends, it takes 0.15-1.0 MPa (22-145 psi) and moves at 30-800 mm/s. Force at 0.5 MPa is 628.3 N out and 527.8 N back; keep real work near 377 N of that push and the same figure equals lifting about 32 kg vertically with a 2:1 margin.

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 MAC40X50SCAH Is Used
Guard gate actuator
Swinging a polycarbonate guard gate on a bottling line; the pivot back cover takes the link and the cushion stops the gate without a metal bang.
Punch-feed pusher
Feeding blanks one at a time into a small punch die, the 50 mm stroke matching the pitch of the feed track.
Thermoform tray ejector
Ejecting formed trays from the tool, where 628 N clears the part and the cushion protects the mould edge from the strike.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X50SCAH the Right Cylinder?
Compare the 32 mm bore (402 N push at 0.5 MPa) if the load is light, or the 50 mm bore (981 N) when margins tighten. Once air is removed the piston is free to move, so a pilot check valve or rod lock is the answer for loads that must not sag. The CA pivot back cover pairs naturally with swing links, FA flange, LB foot and SDB pivot brackets cover fixed mounting, and the standard magnet takes CMSG, DMSG or EMSG switches. Air ports are 1/8 inch on this bore (PT standard, G and NPT optional).
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 MAC40X50SCAH FAQ
At 0.5 MPa: 628.3 N push, 527.8 N pull. At 0.7 MPa: 879.6 N push, 738.9 N pull. The theoretical maximum is 128.1 kgf at 1.0 MPa. The cylinder is double acting, runs 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s and carries a variable cushion at each end.
MAC is the cushioned round-body mini series, 40 is the bore in mm, 50 is the stroke in mm, S marks the built-in magnet and CA is the pivot back cover; the trailing H is an extra option - confirm it against the datasheet before ordering.
