Airtac MAC Stainless Steel Mini Air Cylinder MAC25X190SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X190SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 190mm 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 MAC25X190SCA
Five millimetres past its 185 mm sibling, the MAC25X190SCA spans a 190 mm stroke on a 25 mm cushioned double-acting body with a CA pivot back cover - air powers the rod out and in, and a variable air cushion at both ports tames end-of-stroke shock so you can run faster cycles without hammering the covers. Force stands at 245.3 N push and 206.1 N pull at 0.5 MPa.
That push rating equals about 25 kgf of lift, so halving for margin means roughly 12 kg raised vertically is a realistic figure. The riveted stainless barrel with hard-chrome rod shrugs off mild corrosion, and the standard built-in magnet lets a CMSG or EMSG switch report position with zero special ordering.

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 MAC25X190SCA Is Used
Depalletizer sweep on a can line
A pivoted sweep powered by this cylinder clears the top layer of empty cans onto a takeaway conveyor; the cushions let the sweep stop softly at high cycle rates.
Lift-assist arm for vial trays
Pivoted on its CA cover, the cylinder raises one end of a loaded vial tray for robotic pickup; the 12 kg vertical margin covers the tray weight plus friction.
Stretching fixture for rubber grommets
The 190 mm stroke pulls a grommet over a fitting on an assembly bench; dialled cushion settings stop the mandrel without snap.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X190SCA the Right Cylinder?
Weigh the 20 mm bore (157.0 N at 0.5 MPa) against the 32 mm bore (402.2 N) to bracket this 25 mm choice; 190 mm of travel stays inside the 500 mm standard stroke window, so no made-to-order pricing applies. On strokes this long, guide the load externally - a 10 mm rod pushed hard from a cantilever will bend.
Without air the piston offers no hold: the load drifts when the valve centres, so specify a rod lock or pilot check valve for gravity or held loads. The CA pivot back cover matches SDB pivot brackets for swinging mounts, while FA flange and LB foot options suit fixed frames. PT ports are default, with G and NPT thread suffixes available.
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 MAC25X190SCA FAQ
At 0.5 MPa: 245.3 N push, 206.1 N pull. At 0.7 MPa: 343.4 N push, 288.5 N pull. Theoretical maximum 50.0 kgf at 1.0 MPa. Supply air 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-800 mm/s. Port size 1/8", rod 10 mm, rod thread M10x1.25.
It adds a pivoting eye at the rear cover so the cylinder can swing with a lever or link arm - no fabricated bracket needed. Combine it with an SDB pivot bracket, or choose FA flange / LB foot for rigid frames; the built-in magnet for CMSG, DMSG and EMSG switches stays standard in every version.
