Airtac MAC Stainless Steel Mini Air Cylinder MAC40X75SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X75SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 75mm 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 MAC40X75SCM
The MAC40X75SCM pairs a 75 mm stroke with AirTAC's riveted round-body build: a stainless-steel barrel rolled onto aluminium-alloy covers, driving a hard-chrome plated 16 mm rod. It is double acting - air extends and retracts - pushing 628 N and pulling 528 N at 0.5 MPa, rising to 880 N at 0.7 MPa. The CM round-end back cover gives a clean pivot point with no extra clevis bracket.
At 0.5 MPa, plan on roughly 377 N of usable push rather than the full 628 N rating, enough headroom for clamping or feeding parts with confidence. Run it 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air, and dial the variable air cushion at each end so stops stay soft even at top speed. Every unit ships with the piston magnet fitted as standard, so CMSG, DMSG or EMSG switches clip straight onto the barrel.

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 MAC40X75SCM Is Used
Carton reject gate on a packaging line
Swings a pusher gate across a carton conveyor to divert rejects; 628 N at 0.5 MPa overcomes belted product drag, and the cushioned ends absorb the snap of each divert cycle.
Bench staking and marking fixture
Drives a small staking die on a bench fixture; the 75 mm stroke clears part loading, and the CM round-end cover lets the cylinder pivot for angled setups.
Lid press on a washdown tray filler
Presses snap-on lids onto food trays; the stainless barrel and hard-chrome rod handle repeated hose-down far better than painted mini cylinders.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X75SCM the Right Cylinder?
Sizing check: the 32 mm bore pushes 402 N at 0.5 MPa if your load is lighter, while the 50 mm bore reaches 981 N for heavier work. This 40 mm bore breathes through 1/8" ports and carries an M12x1.25 male rod thread. It will not hold position on its own - when air pressure drops or the valve centres, the rod simply drifts, so specify a rod lock or pilot check valve for held loads. Mount with FA flange or LB foot brackets, or an SDB pivot, and count on the built-in magnet to drive CMSG, DMSG or EMSG switches without ordering a special piston.
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 MAC40X75SCM FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N; at 0.7 MPa that rises to 880 N push and 739 N pull. The theoretical maximum at 1.0 MPa is 128 kgf. The cylinder is double acting on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, proof tested to 1.5 MPa (215 psi), with rod speeds of 30-800 mm/s.
Both ends have a variable cushion controlled by needle screws. Start with the needles open so the piston can reach the covers, then close them gradually until the stop is firm but not harsh. A properly set cushion lets you run faster cycles or carry heavier decelerating loads without hammering the aluminium covers.
