Airtac MAC Stainless Steel Mini Air Cylinder MAC25X500SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X500SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 500mm 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 MAC25X500SCM
A round-end CM back cover is the signature of the MAC25X500SCM, letting a clevis or pin link attach directly for the full 500 mm of double-acting, cushioned travel. At 0.5 MPa the bore pushes 245 N (206 N pulling) and 343 N at 0.7 MPa - roughly a 12 kg vertical lift with a 2:1 margin, or 147 N of dependable horizontal work.
The riveted stainless barrel and 20 um hard-chrome rod stand up to damp production halls, and because the piston magnet is factory-fitted, CMSG, DMSG and EMSG switches read stroke position straight away at speeds of 30-800 mm/s. Ports are 1/8" and the rod carries an M10x1.25 male thread for standard accessory hardware.

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 MAC25X500SCM Is Used
Pass-through gate drive
Drives a sliding gate on a cleanroom pass-through cabinet, the round-end cover taking a simple pin link.
Label head tamper
Presses a tamper pad onto labels after a 500 mm approach on a washdown labeler head.
Order-pick chute latch
Latches an order-picking chute in a small-parts warehouse, magnet switches confirming latch position at both ends.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X500SCM the Right Cylinder?
Weigh a 20 mm bore (157 N push at 0.5 MPa) against 32 mm (402 N) to confirm 25 mm is right; for 500 mm strokes it usually is, provided side loads stay low or a guide rail is fitted. Supply arrives through a 1/8" port at 0.15-1.0 MPa (22-145 psi). Should the job need the rod to hold under load when the valve centres, plan on an external rod lock or pilot check valve - the cylinder itself will coast. Fixed frames use FA flange or LB foot brackets alongside the CM round-end cover.
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 MAC25X500SCM FAQ
The 25 mm bore produces 245.3 N forward and 206.1 N return at 0.5 MPa, rising to 343.4 N and 288.5 N at 0.7 MPa; the theoretical maximum is around 50 kgf at 1.0 MPa. Rod thread is M10x1.25 on a 10 mm rod.
It provides a rounded boss that accepts a pivot pin or clevis directly, so swing links and latch arms connect without an added bracket. If you prefer a fixed mount, FA flange, LB foot or SDB pivot brackets bolt to the same body, and the standard magnet still works with CMSG, DMSG and EMSG switches.
