Airtac MAC Stainless Steel Mini Air Cylinder MAC50X25SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X25SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 25mm 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 MAC50X25SCM
Need nearly a kilonewton from a cylinder shorter than your hand? The MAC50X25SCM pairs a 50 mm bore with a 25 mm stroke in AirTAC's riveted round-body mini format: stainless barrel, hard-chrome plated rod, aluminium covers rolled tight against the tube. Double-acting with a variable air cushion at each end, it pushes 981 N and pulls 881 N at 0.5 MPa, rising to 1374 N of push at 0.7 MPa. The cushions let you speed up the stroke without shocking the covers, and the CM round-end back cover mounts flush against a flat machine face.
Because the stainless barrel and chrome rod tolerate moisture, splash and mild washdown, this is a sensible pick over painted-steel minis in food-adjacent or humid cells. For sizing math, the 981 N push equals a vertical lift of about 100 kg; keep a 2:1 margin and plan on roughly 50 kg, or on about 589 N of horizontal work force at 0.5 MPa.

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 MAC50X25SCM Is Used
Tube weldment clamps
Fixture clamps on a motorcycle frame line use the 981 N push to hold tubes square while the 25 mm stroke retracts clear for loading.
Carton divert gates
A packaging conveyor snaps divert gates across the lane with this bore; cushioned ends stop the gate even at 800 mm/s top speed without rattle.
Lab compaction press
Sample-compaction rigs in a materials lab draw on about 589 N of practical 0.5 MPa force, with the stainless barrel wiping down easily after spills.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X25SCM the Right Cylinder?
The 40 mm bore delivers 628 N at 0.5 MPa and often suffices for lighter clamps; jump to the 63 mm bore at 1558 N only when your load demands it. This cylinder has no internal latch - if supply air fails or the valve centres, the piston coasts, so add a pilot check valve or rod lock wherever a load must stay put. Ports are 1/4" on the 50 mm bore, rod thread is M14x1.5, and the 25 mm stroke sits well inside the 500 mm standard range. CM round-end cover plus an SDB pivot bracket or LB foot covers most fixture layouts; the standard magnet accepts CMSG, DMSG and EMSG switches out of the box.
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 MAC50X25SCM FAQ
At 0.5 MPa it pushes 981 N and pulls 881 N; at 0.7 MPa that becomes 1374 N push and 1233 N pull. Theoretical peak is 200 kgf at 1.0 MPa. Supply pressure range is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, port 1/4", rod 16 mm threaded M14x1.5.
Its domed round end seats into cradles or against flat plates for a clean, compact installation without adapter blocks. The air cushion at each end is variable - back the needle screws off on first run-up, then close them gradually until end-of-stroke shock disappears.
