Airtac MAC Stainless Steel Mini Air Cylinder MAC25X620SCMH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X620SCMH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 620mm 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 MAC25X620SCMH
Need a 620 mm reach from a compact bore? The MAC25X620SCMH answers with a made-to-order 25 mm stroke on AirTAC's round mini format, double acting and fitted with variable air cushions at both ends. Expect 245.3 N on the extend stroke and 206.1 N retracting at 0.5 MPa; sizing around 147 N of working force keeps the design comfortable.
The CM round-end back cover takes a pivot pin directly, letting the body swing with linkages instead of fighting them. A stainless rolled barrel and 20 um hard-chrome plated rod resist corrosion in humid plants, and with the magnet included as standard, CMSG / DMSG / EMSG switches mount anywhere along the tube.

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 MAC25X620SCMH Is Used
Case flap folder
Swings a long linkage arm to fold carton flaps on a case packer; the CM pivot end tracks the arm's arc through the full 620 mm travel.
Paint-shaker lift assist
Raises a light shaker platform through 620 mm; sized near 147 N of working force, the bore carries a 12 kg platform with margin to spare.
Lab enclosure gate
Opens a stainless process-enclosure gate in a wet chemistry lab, where painted mini cylinders rust out within months.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X620SCMH the Right Cylinder?
A 20 mm bore gives 157.0 N at 0.5 MPa if the load is light; a 32 mm bore pushes 402.2 N when it is not. Because the stroke passes the 500 mm standard limit, this unit is quoted as a made-to-order build. The trailing H code in the model number is not a standard catalogue option - confirm from datasheet before ordering. When pressure drops, the piston stops wherever it happens to be, so fit a pilot check valve or rod lock for held loads.
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 MAC25X620SCMH 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 peak 50.0 kgf at 1.0 MPa. Air supply 0.15-1.0 MPa (22-145 psi), speed range 30-800 mm/s, 1/8" PT port.
CM is a round-end cover with a pivot hole, so the cylinder can be pin-mounted to swing with a lever or linkage - no separate bracket required. Combined with the stainless rolled barrel and the standard magnet (CMSG / DMSG / EMSG ready), it suits long-reach, damp-environment linkages like this 620 mm build.
