Airtac MAC Stainless Steel Mini Air Cylinder MAC40X175SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X175SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 175mm 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 MAC40X175SCM
For a 175 mm stroke in the 40 mm class, the MAC40X175SCM pairs 628 N of push and 528 N of pull at 0.5 MPa with a round-end CM back cover that suits compact pivoting installs. The body is a riveted round tube - stainless barrel, aluminium-alloy covers - so alignment stays true and the barrel tolerates moisture and mild chemicals.
A variable cushion at each end lets you run up to 800 mm/s without the covers taking the hit. The magnet ships standard for CMSG / DMSG / EMSG switching. Budget about 377 N for real work at 0.5 MPa - the 60% figure experienced buyers use - and you still hold headroom for friction and pressure dips.

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 MAC40X175SCM Is Used
Sorter carton stop
Stops and releases cartons on an intralogistics sorter; the 175 mm stroke sets the gate clear of the passing flow and the cushions quiet each cycle.
Filling head lift
Raises a dosing head 175 mm between vials on a filling machine, with the 16 mm hard-chrome rod resisting splashes and cleaning agents.
Jig slide clamp
Clamps a workpiece in a welding jig; roughly 377 N of usable force holds the part against weld shrinkage without crushing it.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X175SCM the Right Cylinder?
Compare 0.5 MPa push figures when sizing down or up: the 32 mm bore makes 402 N, the 50 mm bore 981 N. Pressure spans 0.15-1.0 MPa (22-145 psi). Mount with an FA flange for face fixing, an LB foot under the body, or an SDB pivot bracket; the CM round-end back cover keeps the rear compact. Ports are 1/8" and the rod thread M12x1.25. Because the piston is double acting with no internal detent, it will coast if air is lost - for a load that must not move, add a pilot check valve or rod lock downstream.
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 MAC40X175SCM FAQ
0.5 MPa gives 628 N push and 528 N pull; 0.7 MPa gives 880 N push and 739 N pull; theoretical peak is about 128.1 kgf at 1.0 MPa. Pressure window 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
Yes - the magnet is built into the piston as standard, not an option. CMSG, DMSG and EMSG sensors snap onto the round barrel and slide to the switching point, giving end-of-stroke or mid-stroke signals along this 175 mm travel.
