Airtac MAC Stainless Steel Mini Air Cylinder MAC40X210SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X210SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 210mm 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 MAC40X210SCA
With 210 mm of travel and 628.3 N of push at 0.5 MPa, this 40 mm bore MAC suits long reach-over and transfer motions. It is double acting, and the variable air cushion at each end can be opened gradually to suit 30-800 mm/s speeds and heavy loads. Operating range is 0.15-1.0 MPa (22-145 psi), with proof pressure of 1.5 MPa (215 psi). Ports are 1/8" on this bore.
The CA pivot back cover lets the body swing on a pin - useful for arc and gate movements - and FA flange, LB foot or SDB pivot mounts bolt on when a fixed frame is preferred. The stainless barrel resists washdown-style damp; plan real loads around 377 N rather than the full 628.3 N rating.

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 MAC40X210SCA Is Used
Carton transfer pusher
Pushes cartons across a 200 mm pitch transfer plate on a packing line, cushioned for reliable 800 mm/s cycling at the end of each stroke.
Tote bin tipper
Swings small tote bins into a dump chute on the CA pivot pin; 628.3 N at 0.5 MPa tips loaded bins under cushioned control.
Vial rack lifter
Raises a vial rack 210 mm between washing and filling stations on a pharma line, with external rails guiding the rack so the rod sees thrust only.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X210SCA the Right Cylinder?
At 210 mm of stroke keep side loads off the 16 mm rod - guide the load externally with linear rails or a cam so the rod sees pure thrust. Force-wise, a 32 mm bore offers 402.2 N at 0.5 MPa while a 50 mm bore steps up to 981.3 N; this 40 mm bore's 628.3 N fits most transfer duties between them.
The CA pivot back cover lets the body swing on a pin, useful for arc and gate movements, and FA flange, LB foot or SDB pivot mounts bolt on when a fixed frame is preferred. If power fails mid-travel the piston coasts, so specify a rod lock or pilot check valve wherever the load must stay parked.
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 MAC40X210SCA FAQ
Push at 0.5 MPa is 628.3 N and pull is 527.8 N; at 0.7 MPa it is 879.6 N push against 738.9 N pull. The theoretical peak at 1.0 MPa is 128.1 kgf. Working near 377 N keeps a healthy service margin over the long stroke.
It carries a pivot pin so the body can swing in an arc without extra brackets. If the frame prefers a fixed mount, FA flange, LB foot or SDB pivot hardware bolts on, and I or Y rod knuckles cover the load end.
