Airtac MAC Stainless Steel Mini Air Cylinder MAC40X150SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X150SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 150mm 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 MAC40X150SCM
Stainless round barrel, riveted covers, hard-chrome rod - MAC40X150SCM is built to shrug off the damp corners of a plant where painted minis corrode. At this 40 mm bore you get 628 N pushing and 528 N pulling at 0.5 MPa, climbing to 880 N and 739 N at 0.7 MPa, over a 150 mm stroke.
The CM round-end back cover gives a clean fixed stud mount without brackets. Both ends carry a variable air cushion - dial the needle screws in stage by stage during commissioning so heavy loads land soft even at the top of the 30-800 mm/s speed range. Halve the push figure and this cylinder lifts roughly 32 kg vertically with margin to spare; the standard piston magnet pairs with CMSG, DMSG and EMSG switches.

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 MAC40X150SCM Is Used
Washdown Mixer Hatch
Lifts the inspection hatch on a food-plant mixer that gets hosed daily; the stainless barrel and chrome rod stand up to rinse water that ruins painted cylinders.
Carton Case Pusher
Pushes filled cartons into a case packer; 628 N at 0.5 MPa moves a full lane of boxes and the cushion stops the pack slamming the end plate.
Index Gate on Dial Table
Trips the index gate of a rotary dial assembly table; the CM round end bolts flat to the frame and a DMSG switch confirms the gate is home.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X150SCM the Right Cylinder?
Downsizing to 32 mm leaves you 402 N push at 0.5 MPa, while 50 mm jumps to 981 N - the 40 mm bore is the sweet spot when the demand sits between those. Treat 377 N as the practical working push at 0.5 MPa and the cylinder will last. This is a double-acting part with no position memory: if supply air drops, the rod moves, so add a rod lock or check valve where a load must stay put. SDB pivot, LB foot and FA flange accessories all fit, and the 1/8" ports take standard fittings.
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 MAC40X150SCM FAQ
Push 628 N and pull 528 N at 0.5 MPa; push 880 N and pull 739 N at 0.7 MPa; theoretical maximum 128.1 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi), withstands 1.5 MPa (215 psi) proof pressure, and travels 30-800 mm/s.
The round end presents a flat, bracket-free face for stud or plate fixing against machine frames. Together with the riveted stainless barrel and grease-storing piston seal, it keeps a compact profile in tight assemblies - and the built-in magnet means EMSG sensing needs no special order.
