Airtac MAC Stainless Steel Mini Air Cylinder MAC40X225SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X225SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 225mm 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 MAC40X225SCM
With its round-end CM back cover, the MAC40X225SCM hangs from a rear pin in swing-link and rod-eye layouts where a flat cover would foul the motion. The 40 mm piston delivers 628.3 N pushing and 527.8 N retracting at 0.5 MPa, and the two-way variable cushion lets you tune deceleration at both ends of the 225 mm stroke.
Practical sizing: keep continuous work near 377 N, comfortably under the rated push, and count on about 32 kg of vertical lifting per cylinder with a 2:1 margin. Built as a riveted stainless tube with a hard-chrome 16 mm rod, it tolerates coolant splash and outdoor exposure that would rust painted mini bodies. The magnet comes standard, so CMSG, DMSG and EMSG switches fit on for end-of-stroke signals.

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 MAC40X225SCM Is Used
Kicker on a bottling line
Diverts bottles at a lane change; tuned cushions let the swing arm run fast through thousands of cycles without slamming.
Ejector under a stamping press
Pushes formed blanks out of the die area with up to 628.3 N, clearing the nest before the next press stroke.
Hopper gate on a powder feeder
Opens and closes a slide gate under a hopper; the round-end cover carries the link as the gate mechanism arcs open.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X225SCM the Right Cylinder?
If the return stroke is the weak point, note pull is 527.8 N at 0.5 MPa - the 50 mm bore reaches 880.8 N while the 32 mm bore gives only 345.6 N. Position is not retained without air, so a pilot check valve or rod lock is needed on held loads. Mount with FA flange or LB foot plates, an SDB pivot bracket, or I and Y knuckles threaded onto the M12x1.25 rod end.
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 MAC40X225SCM 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 limit is 128.1 kgf at 1.0 MPa. Supply is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, air filtered to 40 um.
The 40 mm bore takes 1/8 inch ports and the carbon-steel rod is 16 mm in diameter with an M12x1.25 thread. This code comes with PT threads as standard, and G or NPT can be ordered via the thread suffix. Strokes up to 500 mm are standard; longer ones are made to order.
