Airtac MAC Stainless Steel Mini Air Cylinder MAC25X300SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X300SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 300mm 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 MAC25X300SU
Where a fixture needs a flat face to bolt against, the U flat-end back cover of the MAC25X300SU does the job - a 25 mm bore pushing 245.3 N at 0.5 MPa over 300 mm of travel. The cylinder is double acting with a variable air cushion at both ends, so you can open the needle screws on first run and then tune shock out as the load grows. Inside, a two-way piston seal doubles as a grease reservoir; outside, the stainless round barrel and hard-chrome plated rod (20 um) shrug off the humid, mildly corrosive air that ruins painted mini cylinders.
The magnet comes standard on the piston, so CMSG, DMSG or EMSG switches mount straight onto the barrel for end-of-stroke signals - no special piston and no paid option. On real work budget about 147 N of push at 0.5 MPa, and for vertical lifts count on roughly 12 kg with a 2:1 margin. Speed range is a wide 30-800 mm/s across a 0.15-1.0 MPa (22-145 psi) supply; proof pressure is 1.5 MPa (215 psi).

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 MAC25X300SU Is Used
Curing oven door pusher
Slides open the doors on a powder-coat curing oven; 300 mm of travel covers the door track and the flat U cover bolts straight to the frame.
Sample elevator in a lab autoloader
Raises sample racks of about 12 kg between analyser decks; the built-in magnet feeds a CMSG switch so the PLC knows the rack is home.
PCB pallet push-off
Ejects loaded SMT pallets from a cooling conveyor; cushioning at both ends protects fragile boards from end-of-stroke jolt.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X300SU the Right Cylinder?
Compare neighbours before ordering: the 20 mm bore manages only 157 N of push at 0.5 MPa while the 32 mm reaches 402.2 N, so this 25 mm barrel is the pick when loads land between those two. Air pressure never locks the piston in place; if the supply drops or the valve centres under a hanging load the rod sags, and a rod lock or pilot check valve is the fix for held positions. Bolt the flat U back cover straight onto a machine plate, or add FA flange, LB foot or SDB pivot mounting from the code. Over 300 mm of travel even small side loads bend the 10 mm rod - keep the push axial and use the M10x1.25 rod thread with a knuckle where the line of force is not perfect. Ports are 1/8".
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 MAC25X300SU FAQ
Push is 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa push climbs to 343.4 N, and the theoretical maximum is 50 kgf at 1.0 MPa. Supply pressure runs 0.15-1.0 MPa (22-145 psi), proof is 1.5 MPa (215 psi), speed 30-800 mm/s.
The flat end cover bolts straight onto a machine plate without brackets, while the built-in piston magnet accepts CMSG, DMSG or EMSG switches anywhere on the stainless barrel, giving you a flush-mounted cylinder that still reports position.
