Airtac MAC Stainless Steel Mini Air Cylinder MAC40X50SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X50SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 50mm 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 MAC40X50SCA
Behind a riveted stainless-steel barrel and a 16 mm hard-chrome plated rod, the MAC40X50SCA runs double acting with an adjustable air cushion at each end. At the usual 0.5 MPa shop air it pushes 628.3 N and pulls 527.8 N - roughly 64 kg of raw thrust - placing this 50 mm stroke in the mid-duty class of round mini cylinders. The chrome rod and steel tube also shrug off rinse-down and humidity that ruin painted minis.
Plan real work at about 377 N (0.6 x the 628.3 N rating) so the rod and seals last; that figure equals lifting roughly 32 kg vertically with a 2:1 margin. The CA pivot back cover swings on a pin with no extra brackets, and because the magnet ships as standard, CMSG / DMSG / EMSG switches clip straight onto the barrel for end-of-stroke signalling.

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 MAC40X50SCA Is Used
Brewery carton pusher
Nudging 20 kg cartons sideways on a bottling-line conveyor at up to 800 mm/s - the twin cushions absorb the stop without hammering the covers.
Weld fixture clamp
Clamping sheet-metal panels in a jig, using the 628.3 N push at 0.5 MPa across a short 50 mm close-up move.
Filling-head lid press
Pressing snap lids onto 25 kg tubs on a filling line; the 50 mm stroke with cushioned landing keeps cycles quiet at speed.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X50SCA the Right Cylinder?
The 40 mm bore delivers 628.3 N at 0.5 MPa and 879.6 N at 0.7 MPa; if that is more than the job needs, the 32 mm bore gives 402.2 N, while stepping up to 50 mm bore nearly doubles thrust to 981.3 N. A plain MAC coasts when air is lost, so add a rod lock or pilot check valve wherever the load must stay put. 1/8" PT ports and an M12x1.25 male rod thread are standard; FA flange, LB foot or SDB pivot brackets bolt on if the CA pivot alone does not suit the frame.
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 MAC40X50SCA FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa those rise to 879.6 N push and 738.9 N pull. Theoretical maximum force at 1.0 MPa is 128.1 kgf. Operating pressure spans 0.15-1.0 MPa (22-145 psi) with proof pressure 1.5 MPa (215 psi), and speed runs 30-800 mm/s.
The barrel is a high-precision stainless tube with rolled-on aluminium covers and a 20 um hard-chrome plated carbon-steel rod, so the body resists mild corrosion and washdown far better than painted-steel or plain aluminium minis in damp, food or outdoor spots.
