Airtac MAC Stainless Steel Mini Air Cylinder MAC40X650SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X650SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 650mm 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 MAC40X650SCM
Some machines simply need reach, and this made-to-order 650 mm stroke on a 40 mm bore delivers it without giving up force: 628 N push at 0.5 MPa, rising to 880 N at 0.7 MPa. Double acting throughout, with needle-adjustable air cushions at both ends that matter even more as stroke, and therefore impact energy, grows.
Derate for durability and the numbers still work: about 377 N of usable push at 0.5 MPa, enough to index a 35 kg pallet on low-friction guides. The CM round-end back cover offers a pivoting fixing without extra hardware, the stainless barrel with hard-chrome rod laughs off washdown mist, and the standard magnet keeps CMSG, DMSG and EMSG switches on the menu from day one.

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 MAC40X650SCM Is Used
Deep-rack pick pusher
Pushes totes off the back of a 650 mm deep pick slot; the variable cushion absorbs the impact at full extension.
Cable carriage drive
Drags a cable-chain carriage along a machining center; guided tooling keeps the long rod straight over the full travel.
Battery bay latch actuator
Latches forklift battery compartments on washdown-prone charging bays; the stainless body resists battery mist and rinse-down.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X650SCM the Right Cylinder?
Check the neighbors before committing: 402 N from a 32 mm bore or 981 N from a 50 mm bore at 0.5 MPa may fit better than this in-between 628 N. Long strokes punish side loads, so guide the payload externally and keep thrust axial. Air lost equals motion lost on any double-acting MAC, the rod simply coasts, so park loads with a rod lock or pilot check valve. The CM round-end cover can be swapped for CA pivot or U flat-end just by changing the code; 1/8" ports are standard on this bore.
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 MAC40X650SCM FAQ
Push is 628.3 N and pull 527.8 N at 0.5 MPa; at 0.7 MPa expect 879.6 N and 738.9 N respectively. The theoretical maximum is 128.1 kgf at 1.0 MPa, all within a 0.15-1.0 MPa (22-145 psi) working band at 30-800 mm/s.
No. Every MAC-series cylinder, this one included, ships with the piston magnet already fitted, so CMSG, DMSG or EMSG switches mount straight onto the barrel for end-of-stroke or mid-stroke signals with no special-order piston.
