Airtac MAC Stainless Steel Mini Air Cylinder MAC40X100SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X100SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 100mm 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 MAC40X100SCM
Built around a 40 mm stainless barrel rolled shut rather than tied together, the MAC40X100SCM is a double-acting mini cylinder with a variable air cushion at both ends. At 0.5 MPa it pushes with 628 N and pulls with 528 N; at 0.7 MPa those figures climb to 880 N and 739 N, with a theoretical ceiling of 128.1 kgf. The CM round-end back cover gives you a clean pivot point without a separate bracket.
The hard-chrome plated 16 mm rod shrugs off washdown and damp air, and the built-in magnet (standard, not an option) lets CMSG, DMSG or EMSG switches clip straight on. Because the cushion is adjustable, run the needle screws fully open at first start, then close them gradually to trim shock while running 30-800 mm/s. In day-to-day terms, budget around 377 N of real work at 0.5 MPa, or plan on the rod lifting about 32 kg vertically with margin to spare.

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 MAC40X100SCM Is Used
Cookie-line tray lifting
Raising filled trays of about 30 kg straight up suits the 528 N pull force, and the double cushion lands each tray gently anywhere in the 30-800 mm/s band.
Carton diverting gate
A pivoted pusher gate deflecting cartons needs the CM round-end cover; about 377 N of working push at 0.5 MPa moves loaded cases without slamming.
Welding-jig clamp fixture
Clamping steel parts at up to 880 N at 0.7 MPa, with the standard magnet feeding CMSG switch signals back to the PLC for cycle verification.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X100SCM the Right Cylinder?
Compare bores before committing: 25 mm gives 245 N push at 0.5 MPa and 50 mm gives 981 N, so the 40 mm sits squarely in the mid-force band. Ports are 1/8" on this bore and the male rod thread is M12x1.25. Remember the piston floats when air is removed - a centred valve will not hold a vertical load, so pair the cylinder with a rod lock or pilot check valve where holding matters. The CM round-end cover suits SDB pivot brackets, while FA flanges and LB feet handle rigid frames.
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 MAC40X100SCM FAQ
At 0.5 MPa: 628 N push and 528 N pull. At 0.7 MPa: 880 N push and 739 N pull. The theoretical maximum is 128.1 kgf at 1.0 MPa. Supply air between 0.15-1.0 MPa (22-145 psi); proof pressure is 1.5 MPa (215 psi).
It provides a built-in pivot point for swinging or linking motions, so no extra bracket is needed. FA flange, LB foot and SDB pivot mounts are also available, and the standard piston magnet supports CMSG, DMSG and EMSG switches straight away.
