Airtac MAC Stainless Steel Mini Air Cylinder MAC40X65SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X65SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 65mm 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 MAC40X65SCM
A rounded back cover gives fabricators freedom to pin or weld their own linkage eyes, and that is exactly what the CM option brings to the MAC40X65SCM. Behind it sits a 40 mm bore developing 628 N at 0.5 MPa, double acting with a variable cushion at each end across a 65 mm stroke.
Mild rust and rinse-down hold no fears for the stainless tube, and the 20 um hard-chrome rod shields the seals from abrasive dust. Plan steady duty at about 377 N - the 60 percent figure - which lifts roughly 32 kg vertically with margin. The magnet is on board as standard, so DMSG, CMSG or EMSG switches snap on for end-of-stroke signals the day it arrives.

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 MAC40X65SCM Is Used
Sortation merge gate
A swing gate flips totes onto a sortation spur, hinged on a linkage pinned straight to the CM round end.
Web tension arm
The cylinder strokes a tension roller to hold film tension steady on a compact winding machine.
Hopper metering gate
A slide gate meters granulate from a small hopper above a bagging station, cushioned so each close is quiet.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X65SCM the Right Cylinder?
A 32 mm bore manages 402 N at 0.5 MPa and a 50 mm bore 981 N, so this 40 mm unit sits mid-range for push-pull work. When the valve centres, expect drift rather than a lock; pilot check valves or a rod lock hold the load instead. Supply it 0.15-1.0 MPa (22-145 psi) and cycle anywhere from 30 to 800 mm/s. The CM round end suits pinned linkages; choose the CA pivot cover or U flat-end where they fit better, with FA flange, LB foot and SDB brackets behind them.
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 MAC40X65SCM FAQ
Double-acting on a 40 mm bore: 628.3 N extend force and 527.8 N retract at 0.5 MPa, 879.6 N extend at 0.7 MPa, and 128.1 kgf theoretical maximum at 1.0 MPa.
No - every MAC ships with the magnet built into the piston. Clip a CMSG, DMSG or EMSG switch onto the barrel and you have end-of-stroke detection; no special-order piston, no waiting on a custom build.
