Airtac MAC Stainless Steel Mini Air Cylinder MAC40X800SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X800SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 800mm 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 MAC40X800SCM
Built as a riveted round-body mini, this bore 40 unit runs an 800 mm made-to-order stroke (the standard ceiling for this bore is 500 mm) and pushes 628.3 N at 0.5 MPa, rising to 879.6 N at 0.7 MPa. The stainless-steel barrel and 20 um hard-chrome plated rod handle washdown and damp plant air far better than painted-steel minis, while the variable air cushion at both ends soaks up the shock a long rod can generate at speed.
Air drives the rod both ways, so retraction also carries 527.8 N at 0.5 MPa. Plan real work around 377 N (about 60 percent of the push rating) at 0.5 MPa, which lifts roughly 32 kg vertically with a 2:1 margin. The magnet comes standard, so CMSG, DMSG or EMSG switches drop straight on, and the CM round-end back cover gives a tidy fixed mount without adapters.

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 MAC40X800SCM Is Used
Vertical pallet gate actuation
Runs a crate-stop gate on a warehouse pallet elevator: 377 N of usable push at 0.5 MPa lifts the gate and its load, and the 800 mm stroke clears a tall stack in one move.
Deep-reach loading pusher
Slides dough trays into the far row of a bakery rack loader; the long made-to-order stroke reaches across the rack while the cushion damps the tray set-down.
Die-cart rail plunger
Locks a stamping die cart rail at the far end of its travel, where the chrome-plated rod shrugs off the coolant mist rising from the press pit.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X800SCM the Right Cylinder?
Between bore 32 (402.2 N push at 0.5 MPa) and bore 50 (981.3 N), this 40 mm bore fits loads needing roughly 377 N of continuous force. With 800 mm of stroke, side load is the enemy: guide the payload on external rails, keep bending off the M12x1.25 rod thread, and confirm rod-buckling limits from datasheet if the compressive duty is heavy. The piston drifts when air drops - a rod lock or pilot check valve holds position instead. Mount with LB foot, FA flange or SDB pivot brackets and I or Y rod knuckles; run on 40 um filtered air at 0.15-1.0 MPa (22-145 psi), 30-800 mm/s. Port is 1/8"; G and NPT threads are order options.
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 MAC40X800SCM FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa push rises to 879.6 N (pull 738.9 N). Theoretical maximum is 128.1 kgf at 1.0 MPa. The 800 mm stroke is made to order, above the 500 mm standard maximum for bore 40, and the 1/8" port is shared by all bores 20-40.
Both ends carry a variable air cushion. Back the needle screws off before the first stroke, then close them gradually until end-of-stroke knock stops; the cylinder runs 30-800 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).
