Airtac MAC Stainless Steel Mini Air Cylinder MAC25X130SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X130SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 130mm stroke, 1/8" 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 MAC25X130SU
Tight panels are where the flat-ended U back cover earns its keep on the MAC25X130SU - the cover face sits close to the mount surface and takes bolts directly. Inside, a stainless tube and a 10 mm hard-chrome rod handle humid or rinse-prone areas better than painted mini cylinders. This is a double acting unit: 0.5 MPa gives 245.3 N forward and 206.1 N return on the 25 mm bore.
For a 130 mm job, note the numbers: about 12 kg can be lifted vertically with a 2:1 margin off the 245.3 N rating, and needle cushions at each end absorb the landing as speed climbs toward 800 mm/s. Every piston leaves the factory magnetised, so CMSG, DMSG or EMSG switches sense position without a special order. Where an integrated mount would simplify the frame, the MAR variant carries its bracket built in; this plain MAC takes LB feet, FA flanges or SDB brackets.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 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 MAC25X130SU Is Used
Autosampler elevator
The flat U cover suits a narrow lab chassis; the 12 kg-class vertical margin carries sample racks up 130 mm between deck levels.
Bread-line slice gate
Swings a gate between chutes on a 130 mm throw while the stainless tube wipes clean of flour dust shift after shift.
Blank eject punch
Pushes light-gauge blanks free of a compact press die - 245.3 N at 0.5 MPa with the cushion set soft for thin stock.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X130SU the Right Cylinder?
Between the 20 mm bore (157.0 N at 0.5 MPa) and the 32 mm bore (402.2 N), this 25 mm unit offers a middle path at 245.3 N. Longer strokes like 130 mm ask for clean alignment: side loads bend the slim rod and score the barrel, so guide externally where the load cantilevers. Air loss means motion - the piston coasts to whichever end gravity or the load favours, so add a pilot check or rod lock when a position must hold. 1/8" ports and an M10x1.25 rod thread keep the plumbing standard.
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 MAC25X130SU FAQ
Double acting, bore 25 mm, stroke 130 mm. Forces: 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with roughly 50 kgf theoretical peak at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, ports 1/8", rod 10 mm.
The rolled stainless barrel and hard-chrome plated rod resist mild corrosion, splash and routine hose-down far better than painted-steel minis. The aluminium covers are not marine-grade, so keep aggressive chemicals off them; confirm media compatibility from the datasheet for harsh wash regimes.
