Airtac MAC Stainless Steel Mini Air Cylinder MAC40X500SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X500SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 500mm 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 MAC40X500SCA
Stroke 500 mm is the ceiling of the standard range for this 40 mm bore, and the MAC40X500SCA still puts out 628 N on extend and 528 N on retract at 0.5 MPa. Air drives the rod both ways, and twin variable cushions - one per end - let you trim stop impact while running anywhere from 30 to 800 mm/s.
The riveted round body wraps a stainless-steel barrel around a 20 um hard-chrome plated steel rod, a pairing that shrugs off washdown and humid plant air where painted minis corrode. A magnet ships built into the piston, so CMSG, DMSG or EMSG switches clamp on without a special-order piston. For sizing, plan on roughly 377 N of working push at 0.5 MPa - about a 32 kg vertical lift once a 2:1 margin is applied.

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 MAC40X500SCA Is Used
Conveyor gate lift
Swinging reject gates on a bottling line: the CA pivot eyes bolt straight to the gate linkage while the 500 mm stroke clears a full lane width.
Pallet stacker ejector
Pushing formed cartons off a stacker table with around 377 N of working force, the cushions absorbing the stop at full extension.
Electronics test probe
A long-travel press stage in a PCB test station, where DMSG switches on the standard magnet confirm top and bottom of the 500 mm travel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X500SCA the Right Cylinder?
If 628 N at 0.5 MPa overshoots the job, the 32 mm bore (402 N) saves air and money; if the load grows past 900 N, step up to the 50 mm bore (981 N). Keep in mind the MAC drifts freely when air is removed - a rod lock or pilot check valve is needed to hold a mid-stroke position. The CA pivot back cover suits swing links and pivot brackets directly, with FA flange, LB foot or SDB pivot available if the mounting changes. On a 500 mm stroke the 16 mm rod sees real side-load leverage: guide the load externally and keep lateral force minimal.
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 MAC40X500SCA FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa the figures rise to 879.6 N push and 738.9 N pull. Theoretical maximum output at 1.0 MPa is 128.1 kgf. Pressure range is 0.15-1.0 MPa (22-145 psi) and speed spans 30-800 mm/s.
Back both cushion needle screws fully off, then close them gradually until end-of-stroke impact disappears. This variable air cushion works independently at each end and keeps the covers protected at high speeds. Note that the cushion only decelerates the piston - it is not a brake, so a held load still needs a rod lock or check valve.
