Airtac MAC Stainless Steel Mini Air Cylinder MAC25X75SCMLB
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X75SCMLB is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 75mm 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 MAC25X75SCMLB
Foot-mounted and cushioned, the MAC25X75SCMLB bolts flat to a machine plate yet still delivers full bore 25 thrust: 245.3 N out, 206.1 N back at 0.5 MPa. AirTAC rolls the aluminium covers and a stainless block onto the stainless barrel, a riveted joint that stays sealed through vibration, coolant mist and washdown.
Working pressure spans 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s, with needle-screw cushions at both ends to tame fast stops. Size around 147 N of sustained force, or count on roughly 12 kg of vertical lifting capacity with a 2:1 margin. The LB foot base plus the CM round end cover most frame layouts, and the fitted magnet reads position through CMSG, DMSG or EMSG switches as standard.

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 MAC25X75SCMLB Is Used
Bench-mounted leak-test station
The foot base anchors the cylinder to a test bench, where a 75 mm stroke lifts a lid and 245 N of push seats the sealing plate.
Case kick-off on a cartoner
The LB foot bolts to the cartoner frame and kicks stacked cases sideways, while the cushions keep the impact quiet at around 300 mm/s cycle speeds.
Light riveting press
At 0.7 MPa the bore 25 push reaches 343.4 N, enough for staking and light riveting on brackets, with the foot mount resisting the reaction torque.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X75SCMLB the Right Cylinder?
Stepping down to a 20 mm bore drops you to 157 N at 0.5 MPa, while a 32 mm bore raises the push to 402.2 N - pick this 25 mm when mid-range force over a 75 mm stroke is the match. Porting is 1/8" and the rod thread is M10x1.25.
Nothing in a plain MAC clamps the piston: drop the air signal and the load can back-drive the rod, so budget for a pilot check valve or rod lock where a held position is unacceptable.
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 MAC25X75SCMLB FAQ
Push is 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa expect 343.4 N push and 288.5 N pull; the 1.0 MPa theoretical ceiling is 50 kgf. Double acting with cushions at both ends, 0.15-1.0 MPa (22-145 psi) working pressure, 30-800 mm/s speed, 1/8" ports, M10x1.25 rod thread, and the magnet fitted as standard.
Only the mounting. The stainless rolled barrel, 10 mm hard-chrome rod and end cushions are identical to the base model; the foot simply lets the body bolt flat to a plate or rail. A CM pivot end still comes on the back cover, and the built-in magnet keeps CMSG, DMSG and EMSG switch options open.
