Airtac MAC Stainless Steel Mini Air Cylinder MAC25X90SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X90SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 90mm 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 MAC25X90SCA
A 90 mm stroke on the 25 mm bore gives about 245 N of push and 206 N of pull at 0.5 MPa, rising to 343 N at 0.7 MPa, all from a riveted stainless round barrel with a hard-chrome plated rod that shrugs off washdown and mild corrosion - a real edge over painted minis in damp food and outdoor spots. The CA pivot back cover takes a swinging linkage directly, and a variable air cushion at both stroke ends lets you dial out impact so faster cycles do not hammer the covers.
For planning, treat roughly 147 N (six tenths of rated push) as dependable output at 0.5 MPa. Every unit ships with the magnet built in, so a CMSG or DMSG switch drops on for end-of-stroke detection, and speed runs 30-800 mm/s across a 0.15-1.0 MPa (22-145 psi) supply.

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 MAC25X90SCA Is Used
Reject gate on a bottling line
Swinging reject paddles kick underfilled 1 L bottles off a 60 m/min conveyor; the CA pivot mounts straight to the gate arm and the cushion stops the paddle slamming home.
Small press fixture clamping
Clamps aluminium brackets in a drilling fixture; 245 N at 0.5 MPa holds parts through light drilling torque, with the cushion damping the clamp snap.
Sorter divert arm
Pushes cartons between conveyor lanes in a warehouse sorter; the stainless barrel survives humid dock air where painted minis rust.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X90SCA the Right Cylinder?
At 245 N push (0.5 MPa) the 25 mm bore sits between the 20 mm size at 157 N and the 32 mm size at 402 N - step down for light gating, up for heavier clamping. The CA pivot back cover pairs with an SDB pivot bracket or I/Y rod knuckles when the linkage swings; FA flange and LB foot cover fixed installs. Note that the rod drifts once air is removed, so fit a pilot check valve where the load must stay parked. Keep side loads off the rod at this 90 mm stroke - guide the part externally if the motion is not pure push-pull.
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 MAC25X90SCA FAQ
At 0.5 MPa the 25 mm bore pushes 245 N and pulls 206 N; at 0.7 MPa those rise to 343 N and 289 N. The theoretical ceiling is 50 kgf at 1.0 MPa. It runs double acting on 0.15-1.0 MPa (22-145 psi) air at 30-800 mm/s, with 1/8" ports.
Yes - every MAC25X90SCA ships with a built-in magnet as standard, so CMSG, DMSG or EMSG switches clip onto the barrel without ordering a special piston.
