Airtac MAC Stainless Steel Mini Air Cylinder MAC50X35SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X35SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 35mm 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 MAC50X35SU
Short travel, solid muscle: the MAC50X35SU is a 50 mm bore round-body mini cylinder from AirTAC, double acting with a variable air cushion at both ends. At 0.5 MPa it pushes 981 N and pulls 881 N, and at 0.7 MPa push climbs to 1374 N - roughly a 200 kgf class actuator inside a stainless barrel. The 35 mm stroke keeps the installed length tight for jigs and clamping stations.
The riveted stainless-steel barrel shrugs off washdown mist and mild corrosion where painted mini cylinders would blister, and the hard-chrome plated 16 mm rod resists scoring on dusty lines. A magnet ships built in, so CMSG / DMSG / EMSG switches snap on for end-of-stroke detection with no special piston required. With the U flat-end back cover the body bolts flat against a fixture wall, no added bracket needed. Plan on about 589 N of real work at 0.5 MPa rather than the full 981 N rating, and the sizing already carries margin for friction and pressure sag.

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 MAC50X35SU Is Used
Pneumatic press fixture
Pressing bushings into aluminium housings in a small assembly cell - about 589 N of usable force at 0.5 MPa seats light interference fits without a hydraulic unit.
Gate diverter on a packaging line
A 35 mm throw is enough to swing a product gate between two conveyor lanes, and the variable cushion stops the paddle slamming at each end of travel.
Clamp on a weld jig
Holds a steel bracket square during spot welding, with the stainless barrel standing up to coolant mist and grinding dust around the cell.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X35SU the Right Cylinder?
If 981 N at 0.5 MPa is more than the job needs, the 40 mm bore MAC pushes 628 N and runs cheaper; if the load grows, step to the 63 mm bore for 1558 N. Keep in mind a plain MAC does not lock its position when air drops - the rod drifts under load, so add a pilot check valve or rod lock for held loads. The magnet is already in the piston for CMSG / DMSG / EMSG switches, and FA flange, LB foot or SDB pivot brackets bolt on if the U flat-end cover 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 MAC50X35SU FAQ
At 0.5 MPa it pushes 981 N and pulls 881 N; at 0.7 MPa those rise to 1374 N and 1233 N. The theoretical maximum at 1.0 MPa is about 200 kgf. Supply runs 0.15-1.0 MPa (22-145 psi) with speed from 30 to 800 mm/s, and the 1/4 inch ports and M14x1.5 rod thread come fixed with the 50 mm bore.
No. Every MAC ships with the magnet already in the piston, so CMSG / DMSG / EMSG switches mount straight onto the stainless barrel. The U back cover gives a flat face for direct bolting, and if the frame needs more, FA flange, LB foot or SDB pivot brackets are standard options.
