Airtac MAC Stainless Steel Mini Air Cylinder MAC50X185SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X185SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 185mm 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 MAC50X185SU
A riveted round-body mini cylinder with a Dia 50 stainless barrel and hard-chrome plated rod, the MAC50X185SU shrugs off mild corrosion in damp food and washdown zones where painted minis fail. It is double acting - air extends and retracts the rod - and the piston pushes 981.3 N at 0.5 MPa across a 185 mm stroke. Supply pressure spans 0.15-1.0 MPa (22-145 psi) at speeds of 30-800 mm/s, with a variable air cushion at each end.
The U flat-end back cover bolts to a fixed frame with no extra bracket, and the magnet that ships standard with every MA-series cylinder accepts CMSG, DMSG or EMSG switches straight off the barrel. Plan around 589 N of usable force at 0.5 MPa rather than the full rating; that is roughly a 50 kg vertical lift with a 2:1 margin, enough for a loaded slide gate or an ejector pusher.

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 MAC50X185SU Is Used
Dairy tray ejector
Knocks yogurt trays off a washdown conveyor every few seconds; the stainless barrel and 185 mm stroke handle the wet line and the reach, pushing up to 981.3 N.
Press-brake blank clamp
Holds a steel blank against the back gauge before bending; around 589 N of working force is plenty for thin sheet, and the cushion stops the clamp from slamming.
Flour hopper slide gate
Opens a slide gate on a flour silo outlet; with about 50 kg of vertical lift capacity the bore 50 rod raises the gate without jarring the frame.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X185SU the Right Cylinder?
At 981.3 N push, this Dia 50 sits between the bore 40 MAC (628.3 N at 0.5 MPa) and the bore 63 version (1557.9 N), so check your load before stepping up or down. Like every double-acting MAC it drifts when air drops or the valve centres - add a rod lock or pilot check valve if the load must stay put. The flat-end U back cover suits fixed mounts; FA flange, LB foot, SDB pivot and I/Y rod knuckles bolt on for other frames. If the 185 mm stroke sees side loads, guide the load externally to spare the 16 mm rod.
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 MAC50X185SU FAQ
At 0.5 MPa the piston pushes 981.3 N and pulls 880.8 N. At 0.7 MPa those figures rise to 1373.8 N and 1233.1 N, and the theoretical maximum at 1.0 MPa (145 psi) is 200.1 kgf. The rod is 16 mm, ports are 1/4 inch and the male rod thread is M14x1.5.
No. Every MAC50X185SU comes with the piston magnet built in as standard, so CMSG, DMSG and EMSG switches clip onto the stainless barrel on day one - no special-order piston and no waiting.
