Airtac MAC Stainless Steel Mini Air Cylinder MAC25X650SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X650SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 650mm 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 MAC25X650SCA
When 500 mm is not enough, the MAC25X650SCA stretches AirTAC's 25 mm MAC mini cylinder to 650 mm of travel, made to order. It runs double acting with a variable air cushion at each end, so a fast carriage on this long stroke can be slowed gently instead of hammering the covers. The numbers: 245.3 N push and 206.1 N pull at 0.5 MPa, climbing to 343.4 N push at 0.7 MPa.
Both covers are aluminium alloy rolled onto a stainless-steel tube, and the 10 mm carbon-steel rod carries a 20 um hard-chrome plating - a combination that stands up to humid plants and light washdown. The CA back cover gives you a pivot eye as standard, and the piston magnet needs no special ordering; hang a DMSG or EMSG switch on when the PLC wants position. Vertical work check: at 0.5 MPa the rod can lift roughly 25 kg, so size the job at about 12 kg to keep a 2:1 margin.

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 MAC25X650SCA Is Used
Grain elevator gate
A pivoting hopper gate at a grain elevator opens on the CA eye; 245.3 N at 0.5 MPa swings the flap against grain pressure, and the cushion eases it closed.
Print carousel index
On a pad-printing carousel, the cylinder advances the turntable 650 mm per index; a DMSG switch on the standard magnet signals each dwell position.
Sluice blade actuator
A small weir or sluice blade on a water-treatment channel is pushed by the hard-chrome rod; damp, splashed surroundings suit the stainless tube.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X650SCA the Right Cylinder?
Sizing two ways: drop to a MAC20 and you get just 157.0 N push at 0.5 MPa; move to a MAC32 for 402.2 N if the load climbs. Keep the working load near 147 N rather than the full 245.3 N rating to leave headroom.
Remember the MAC is not a position holder - a centred valve or lost air lets the rod drift, so fit a pilot check valve or rod lock where a load must stay put. With 650 mm of stroke, support the load on external guides; side loads will bend the 10 mm rod. LB foot, FA flange and SDB pivot brackets, plus PT, G or NPT ports, are all orderable.
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 MAC25X650SCA FAQ
Push is 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa push rises to 343.4 N with a 50 kgf theoretical maximum at 1.0 MPa. The bore is 25 mm with a 10 mm rod (M10x1.25), ports are 1/8", pressure range 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, and the 650 mm stroke is custom-made.
Both ends carry a variable air cushion with needle screws. Back them fully off before start-up, then close gradually until the stop is firm but not harsh; this keeps 650 mm of moving load from slamming the aluminium covers at speeds up to 800 mm/s.
