Airtac MAC Stainless Steel Mini Air Cylinder MAC25X150SCMLB
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X150SCMLB is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 150mm 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 MAC25X150SCMLB
Foot-mounted frames are where the LB option earns its keep, and this MAC25X150SCMLB pairs it with a 25 mm bore and 150 mm stroke. It runs double acting with a variable air cushion at each end and a standard magnet for CMSG, DMSG or EMSG sensing. AirTAC rolls the aluminium covers onto the stainless barrel in a riveted joint that stays sealed where painted minis corrode, and the 10 mm rod carries 20 um of hard chrome.
The 245.3 N push at 0.5 MPa converts to about 25 kg of thrust; plan for roughly 147 N of that as real work at 0.5 MPa rather than the full rating, with 343.4 N available when supply sits at 0.7 MPa. Needle screws on both cushions let you trim end-of-stroke shock as speeds climb toward 800 mm/s, keeping vibration out of the LB feet.

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 MAC25X150SCMLB Is Used
Saw slide pusher
Drives a sliding stop on a cut-off saw bench, the foot bolts holding the barrel rigid against reaction forces.
Box ejector
Kicks packed boxes off an end-of-line conveyor lane at up to 800 mm/s, the cushions softening each kick.
Pick-light shutter
Opens and closes a gravity-rack pick shutter in a warehouse, with a DMSG switch confirming the closed position.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X150SCMLB the Right Cylinder?
Compare before you commit: the 20 mm bore delivers 157.0 N at 0.5 MPa and the 32 mm bore 402.2 N, so 25 mm at 245.3 N covers the mid-weight band. If the job must hold position through a power loss, remember a plain double-acting cylinder coasts once air leaves it - a pilot check valve or rod lock is the accepted fix. LB feet anchor the body to a machine plate, the CM back cover takes a fixed pin, and align the 10 mm rod true across the 150 mm stroke to avoid side loading. Port thread is PT as standard; G or NPT can be specified at order.
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 MAC25X150SCMLB FAQ
Extension force is 245.3 N at 0.5 MPa and 343.4 N at 0.7 MPa; retraction gives 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa. Theoretical peak is 50.0 kgf at 1.0 MPa. Proof pressure is 1.5 MPa (215 psi) against a working band of 0.15-1.0 MPa (22-145 psi).
LB feet bolt the round barrel flat onto machine plates, which suits pushers and gates that sit on a frame instead of in-line. Together with the CM round-end rear cover you get a fixed base plus a pivot option at the head, while the built-in magnet keeps CMSG, DMSG and EMSG sensing available from day one.
