Airtac MAC Stainless Steel Mini Air Cylinder MAC50X425SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X425SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 425mm stroke, 1/4" 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 MAC50X425SCA
Pivot the load, not just push it: the MAC50X425SCA carries a CA pivot back cover on its 425 mm cushioned stroke, turning a 50 mm double-acting bore into a long swinging motion for gates, tilting trays and hopper doors. Thrust is 981.3 N at 0.5 MPa and pull 880.8 N, so the equivalent of lifting about 100 kg vertically is on the table - halve that to 50 kg for a comfortable 2:1 margin.
The riveted stainless-steel barrel and hard-chrome plated rod stand up to washdown and weather, a real advantage in food plants and outdoor chute work. Because the magnet is standard on every MA-series piston, CMSG, DMSG or EMSG switches drop straight on to flag end positions over the long 425 mm travel. Ports are 1/4", pressure 0.15-1.0 MPa (22-145 psi).

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MAC50X425SCA Is Used
Hopper gate swing
Swings a slide gate open on a grain hopper outlet, the CA pivot tracking the arc without a single extra link bracket.
Dock leveler assist
Helps a pivot-arm dock plate drop into place, cushioned travel easing the 425 mm arc to a soft landing.
Kiln damper tilt
Tilts an exhaust damper blade on a brick kiln, the stainless body coping with radiant heat and airborne dust.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X425SCA the Right Cylinder?
At 0.5 MPa the force ladder runs 628.3 N (bore 40), 981.3 N (this 50 mm bore) and 1557.9 N (bore 63); size up only when your pivot-torque maths demands it. The CA pivot pin takes the arc loads that flat or round covers were never meant to see, while FA flange, LB foot or SDB brackets can still be added. On a 425 mm stroke keep the swing plane free of side load on the 16 mm rod, and note that the rod floats free the moment air is removed - a pilot check valve or rod lock is what actually holds a gate open.
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 MAC50X425SCA FAQ
Push 981.3 N and pull 880.8 N at 0.5 MPa; push 1373.8 N and pull 1233.1 N at 0.7 MPa; theoretical maximum 200.1 kgf at 1.0 MPa. Run it on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, cycling at 30-800 mm/s.
It provides a pivoting mounting point so the cylinder can follow an arc, such as a gate or damper, without extra link brackets. Combine it with FA flange, LB foot or SDB mounts, and the standard built-in magnet works with CMSG, DMSG and EMSG switches.
