Airtac MAC Stainless Steel Mini Air Cylinder MAC40X235SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X235SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 235mm 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 MAC40X235SCM
Stainless round body, chrome-plated 16 mm rod, riveted aluminium covers - the MAC40X235SCM is built for splashy corners of a plant where painted minis rust. Double acting with an adjustable air cushion at both ends, it delivers 628 N at 0.5 MPa and 880 N at 0.7 MPa over a 235 mm stroke.
Treat 377 N as your realistic working force at 0.5 MPa and size tooling to match; the theoretical vertical lift is about 64 kg. The CM round-end back cover keeps mounting flush, and the standard magnet accepts CMSG, DMSG or EMSG switches without ordering a special piston.

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 MAC40X235SCM Is Used
Sample shuttle in a test rig
A 235 mm stroke slides specimen trays between stations, and 628 N holds the tray fixture clamped during a pull test at 0.5 MPa.
Drum lid tug at a mixer
Near 64 kg of theoretical lift means one cylinder can drag a 30 kg mixer lid open, while the stainless body tolerates the splash zone.
Bagging head on a fill line
528 N of pull retracts the bag former at up to 800 mm/s, and both cushions land the head quietly between consecutive bags.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X235SCM the Right Cylinder?
Sizing check: 245 N at 25 mm bore, 628 N here, 981 N at 50 mm - all quoted as push at 0.5 MPa. Remember the MAC free-floats once air is removed; park loads only with a rod lock or pilot-operated check valve downstream. The CM round-end cover presents a clean face for through-hole or bracket mounting, and FA flange or LB foot options bolt on when the frame demands it. Over 235 mm of travel, even small side loads bend a 16 mm rod - guide the payload externally.
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 MAC40X235SCM FAQ
This 40 mm bore yields 628 N push and 528 N pull at 0.5 MPa; 880 N push and 739 N pull at 0.7 MPa; about 128 kgf theoretical at 1.0 MPa. Speed range is 30-800 mm/s with a variable cushion at each end.
The round end suits through-bolt brackets, and FA flange, LB foot or SDB pivot add-ons bolt straight on. CA pivot and U flat-end covers exist in the same series if your frame layout changes later.
