Airtac MAC Stainless Steel Mini Air Cylinder MAC25X185SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X185SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 185mm 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 MAC25X185SCM
Riveted together around a stainless barrel, the MAC25X185SCM is a 25 mm bore, 185 mm stroke mini cylinder with a CM round-end back cover and double-acting cushioned operation - air drives the rod both ways and a variable cushion softens each stop. Expect 245.3 N of push and 206.1 N of pull at 0.5 MPa.
For lifting math, the 245.3 N rating converts to about 25 kgf, so halving for a 2:1 margin means this cylinder comfortably lifts roughly 12 kg vertically. The hard-chrome plated carbon-steel rod resists scoring in dusty plants, and because the magnet ships standard, DMSG or EMSG switches mount on the tube without any special-order piston.

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 MAC25X185SCM Is Used
Benchtop terminal crimp press
Acting as the ram of a light crimping fixture, the 245.3 N push closes terminals on wire harnesses in an automotive sub-assembly cell.
Label applicator press head
The 185 mm stroke presses self-adhesive labels onto jar lids on a food packaging line, where the stainless barrel handles frequent wipe-downs.
Date-code marking on plastic caps
A short-throw marking head driven by this cylinder embosses batch codes on caps; the CM round-end cover bolts flat to the press bridge.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X185SCM the Right Cylinder?
If 245.3 N at 0.5 MPa overshoots your load, the 20 mm bore MAC does 157.0 N; if you need headroom, step to the 32 mm bore and its 402.2 N. This 185 mm stroke sits comfortably within the bore's 500 mm standard limit, though a long thin 10 mm rod prefers externally guided loads.
Air pressure alone positions the piston - centring the valve or losing supply lets the load drift, so fit a pilot check valve or rod lock where holding matters. The CM round-end cover suits clevis-style fixed mounts, and FA flange or LB foot brackets bolt on when the frame demands them.
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 MAC25X185SCM FAQ
Rated 245.3 N push and 206.1 N pull at 0.5 MPa, rising to 343.4 N and 288.5 N at 0.7 MPa, with 50.0 kgf theoretical maximum at 1.0 MPa. It runs on filtered air at 0.15-1.0 MPa (22-145 psi) and survives 1.5 MPa (215 psi) proof pressure. Ports are 1/8", rod thread M10x1.25.
Its round end lets the cylinder sit in simple clevis or fixed cradle mounts without an extra bracket, keeping the envelope short. Add FA flange, LB foot or SDB pivot hardware if your frame needs them; all variants keep the standard built-in magnet for CMSG / DMSG / EMSG sensing.
