Airtac MAC Stainless Steel Mini Air Cylinder MAC40X15SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X15SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 15mm 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 MAC40X15SCM
On a 15 mm stroke the MAC40X15SCM stays compact, yet the 40 mm stainless barrel presses 628.3 N at 0.5 MPa and 879.6 N at 0.7 MPa - enough to seat pins or snap lids. Retraction pulls 527.8 N at 0.5 MPa, so return springs or light loads are never a worry.
Treat about 377 N - 60% of the 0.5 MPa push - as the honest working force, and the rod will hoist around 64 kg straight up, 32 kg with a 2:1 safety factor. The CM round-end cover suits clevis-style linkage, the variable cushion at each end cuts end-of-stroke bang, and every unit ships with its magnet for CMSG, DMSG or 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 MAC40X15SCM Is Used
Carousel part stop
Stops each nest on an assembly carousel; the CM round-end cover pins straight into the linkage arm.
Bench staking tool
879.6 N at 0.7 MPa stakes small terminals over a 15 mm stroke - fast cycles with cushioned landings.
Carton flap hold-down
Presses top flaps while the taper runs, retracting 15 mm in time for the next case.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X15SCM the Right Cylinder?
Sizing neighbours: the 32 mm bore offers 402.2 N and the 50 mm bore 981.3 N at 0.5 MPa, so the 40 mm MAC40X15SCM sits mid-pack for force. Before first run, back the cushion needle screws off and open them gradually to suit your cycle. The CM round-end cover drops into clevis-style linkages; FA flange, LB foot and SDB pivot brackets cover fixed mounts. If a pinned part must stay clamped through an air drop, remember this cylinder drifts without a rod lock or check valve in the line.
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 MAC40X15SCM FAQ
Expect 628.3 N on extend and 527.8 N on retract at 0.5 MPa, climbing to 879.6 N and 738.9 N at 0.7 MPa; the theoretical peak is 128.1 kgf at 1.0 MPa. Supply pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi).
The high-precision stainless barrel with its 20 um hard-chrome plated rod shrugs off mild corrosion and rinse water, a genuine edge over painted-steel minis in food or outdoor plants. Air must be filtered to 40 um, operating temperature spans -20 to +70 C, and speed runs 30-800 mm/s.
