Airtac MAC Stainless Steel Mini Air Cylinder MAC50X65SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X65SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 65mm 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 MAC50X65SU
Flat-ended and fixed: the U back cover on this MAC50X65SU gives a clean face for direct mounting, no pivot hardware needed. The 50 mm bore delivers 981.3 N push and 880.8 N pull at 0.5 MPa, 1373.8 N push at 0.7 MPa - about 200.1 kgf theoretical top force - over a 65 mm stroke.
Being double acting, air retracts the rod as well as extends it, and the variable cushion screws at both ends tame deceleration so you can run up to 800 mm/s without hammering. The stainless round barrel with a hard-chrome carbon-steel rod handles splashes and outdoor air, and the standard magnet accepts CMSG / DMSG / EMSG switches. For vertical work, think of it as lifting about 100 kg, or 50 kg if you want a 2:1 margin.

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 MAC50X65SU Is Used
Machine slide actuation
Bolted by its flat-end U cover to a machine frame, the cylinder extends a 65 mm slide carrying a small drilling head.
Outdoor gate latch
Hard-chrome rod and stainless barrel resist weather on a farm-equipment latch, cycling a 65 mm stroke year-round.
Pallet stopper drop
The 880.8 N pull at 0.5 MPa retracts a stop blade that lets pallets pass one at a time on a packing conveyor.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X65SU the Right Cylinder?
With 981.3 N of push at 0.5 MPa, this bore sits between the 40 mm (628.3 N) and the 63 mm (1557.9 N) options - pick down for space, up for force. There is no holding function inside the cylinder itself: cut the air and the rod moves with the load, so specify a rod lock or pilot check valve for clamps that must not relax. The flat-end U cover suits bolted fixed installs, while FA flange, LB foot or SDB brackets cover other framings and the standard magnet is switch-ready.
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 MAC50X65SU FAQ
Yes: 981.3 N push / 880.8 N pull at 0.5 MPa and 1373.8 N / 1233.1 N at 0.7 MPa, with a 200.1 kgf theoretical peak. Air supply 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, double acting with a variable air cushion at each end.
Included as standard in the piston - no special-order option needed. Any CMSG, DMSG or EMSG switch clamps onto the stainless barrel for position feedback, which suits the flat-end U mounting used on fixed frames.
