Airtac MAC Stainless Steel Mini Air Cylinder MAC50X100SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X100SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 100mm 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 MAC50X100SU
AirTAC's MAC50X100SU pairs a 100 mm stroke with the 50 mm MAC's round stainless-steel barrel, rolled tight against aluminium-alloy covers and a stainless block so the body stays sealed in wet or dusty air. The piston runs double acting - air drives it both ways - and a variable air cushion at each end soaks up shock, while the hard-chrome plated 16 mm rod slides on grease-storing two-way seals. At 0.5 MPa this bore delivers 981 N on extend and 881 N on retract.
In practice, budget for roughly 589 N of dependable push at 0.5 MPa rather than the full 981 N rating, and you will find the flat-end U back cover lands straight onto fixed plates and machine walls without extra brackets. The magnet comes standard, so CMSG, DMSG or EMSG switches drop on for end-of-stroke sensing. Speed range is 30-800 mm/s across a 0.15-1.0 MPa (22-145 psi) supply.

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 MAC50X100SU Is Used
Press-fit station on an appliance assembly line
The 981 N push at 0.5 MPa seats bearings into housing bores over the 100 mm approach, and the variable cushion stops the ram slamming home.
Tray diverters on a washdown food conveyor
Stainless barrel and hard-chrome rod shrug off daily hose-down, while the built-in magnet triggers a CMSG switch to confirm each reject stroke.
Gate pusher on a bottling line infeed
About 589 N of dependable force slides crates of bottles across the lane, with cushioning tuned at both ends for cycling near 800 mm/s.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X100SU the Right Cylinder?
If 981 N of push at 0.5 MPa is more than the job needs, drop to a 40 mm bore (628 N); if the load stalls it, step up to 63 mm (1558 N). Keep in mind this cylinder drifts whenever the valve centres or air is lost - add a pilot check valve or rod lock if the rod must stay put. A 100 mm stroke on a 16 mm rod tolerates little side load, so guide the load externally or fit a Y knuckle to keep the rod straight. SDB pivot brackets, FA flanges and LB feet can be ordered alongside the U back cover.
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 MAC50X100SU FAQ
At 0.5 MPa it pushes 981 N and pulls 881 N; at 0.7 MPa push rises to 1374 N and pull to 1233 N. The theoretical maximum for this 50 mm bore is 200.1 kgf at 1.0 MPa. Air ports are 1/4 inch and the rod thread is M14x1.5.
Back both cushion needle screws fully off before the first strokes, then close them gradually until end-of-stroke noise and rebound disappear. The cushion is variable, not fixed, so you can retune it whenever speed or load changes within the 30-800 mm/s range.
