Airtac MAC Stainless Steel Mini Air Cylinder MAC50X30SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X30SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 30mm 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 MAC50X30SU
A flat-ended U rear cover and a riveted stainless barrel define the MAC50X30SU, a 50 mm bore mini cylinder that is double acting with adjustable air cushioning at both ends. Expect 981 N of push at 0.5 MPa - roughly a 100 kg vertical-lift equivalent - climbing to 1374 N at 0.7 MPa. The 1/4" ports accept 0.15-1.0 MPa (22-145 psi), and speeds run 30-800 mm/s.
The rolled construction clamps the aluminium covers and stainless block straight onto the tube, giving a slim round body that slips between machine plates where bulkier frames will not fit. For sizing, treat about 589 N at 0.5 MPa as your working push budget rather than the full rating. Washdown-friendly stainless tube plus a hard-chrome plated 16 mm rod keep rust at bay in wet or humid plant air.

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 MAC50X30SU Is Used
Pallet divider push
Pushes pallet dividers into racking frames, with the flat rear face bolting directly to the upright.
Small press ejection
Kicks short stamped parts out of a 30 mm die pocket at a bench stamping station.
Damper blade actuator
Swings a ventilation damper blade in a humid food-plant duct where painted bodies would corrode.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X30SU the Right Cylinder?
A 40 mm bore (628 N push) covers lighter jobs; the 63 mm bore (1558 N) is the step up when supply pressure varies. The flat U end sits flush against plates and brackets, and FA flange, LB foot or SDB pivot options adapt the mount further. This cylinder does not lock position when the valve is centred - expect drift unless a rod lock or pilot check valve is added.
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 MAC50X30SU FAQ
The MAC50X30SU at 0.5 MPa produces 981 N push and 881 N pull. Raise supply to 0.7 MPa and it delivers 1374 N push, 1233 N pull. The theoretical force at 1.0 MPa equals 200 kgf. Retraction is weaker than extension because the rod side has less piston area.
Every unit ships with a piston magnet fitted, so CMSG / DMSG / EMSG switches read extend and retract positions right out of the box. Nothing extra to order.
