Airtac MAC Stainless Steel Mini Air Cylinder MAC50X110SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X110SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 110mm 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 MAC50X110SU
A stainless round barrel riveted over a 50 mm bore is the heart of the MAC50X110SU, a double acting mini cylinder with a variable air cushion at each end. Its 110 mm stroke and 1/4" ports suit pick, place and press motions, pushing 981 N and pulling 881 N at 0.5 MPa.
The U flat-end back cover bolts flat to a machine face, so no extra pivot hardware is needed for fixed mounts. Inside, the heterogeneous piston seal stores grease for longer service between overhauls. Sized for vertical work, the 981 N push equals about 100 kgf, so lifting a real part of roughly 50 kg keeps a comfortable 2:1 margin. CMSG, DMSG and EMSG switches mount straight onto the standard built-in magnet.

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 MAC50X110SU Is Used
Tub lid press
Pressing snap lids onto food tubs on a washdown line, where the stainless barrel and chrome rod shrug off daily hosing.
Hopper slide gate
Opening and closing a slide gate on a granulate or grain hopper; 981 N at 0.5 MPa shears a column of free-flowing material.
Bushing press fit
Seating small bushings in an assembly bench fixture, cushioned at both ends to protect the finished bore on landing.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X110SU the Right Cylinder?
For lighter duty the 40 mm MAC40 gives 628 N push at 0.5 MPa; for heavier work the 63 mm bore delivers 1558 N. The MAC holds nothing when air drops - the piston drifts, so specify a rod lock or pilot check valve wherever a load must stay put. Fixed frames suit the U cover directly; pivoting motion calls for the CA cover or an SDB pivot bracket instead.
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 MAC50X110SU FAQ
At 0.5 MPa the 50 mm bore produces 981 N on extension and 881 N on retraction. At 0.7 MPa expect 1374 N push and 1233 N pull, with a theoretical ceiling near 200 kgf at 1.0 MPa. Working pressure is 0.15-1.0 MPa (22-145 psi) and stroke speed 30-800 mm/s.
Needle screws at both ends meter exhaust air, so the deceleration can be dialled in rather than fixed. On commissioning, back the cushion screws off fully and open them gradually until end-of-stroke shock disappears. This lets you run faster cycles or move heavier loads without hammering the covers.
