Airtac MAC Stainless Steel Mini Air Cylinder MAC25X270SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X270SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 270mm 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 MAC25X270SCA
Pivot duty comes built in: the CA cover on this 25 mm MAC carries its own pin, so a take-up arm, clamp lever or gate swings with the body and spares the 10 mm rod from bending. The riveted stainless barrel shrugs off washdown, and double-acting cushioned strokes give 245.3 N push against 206.1 N pull at 0.5 MPa. Supply runs 0.15-1.0 MPa (22-145 psi); travel covers 30-800 mm/s.
For everyday sizing, keep duty near 147 N - the 0.5 MPa push derated 40 percent - and the bore lifts roughly 12.5 kg on a vertical axis with a 2:1 cushion of margin. Turn supply up to 0.7 MPa and the push climbs to 343.4 N. Since the magnet ships inside every MAC in the series, DMSG, CMSG or EMSG switches mount straight on for stroke-end detection.

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 MAC25X270SCA Is Used
Belt Tensioner on a Take-Up Slide
Pivots with the take-up arm to keep steady tension on a packaging-line conveyor belt; 206 N pull at 0.5 MPa holds the idler against spring force.
Bottom-Flap Folder on a Case Erector
A paddle on the CA pin folds carton flaps down; cushioning at both ends quiets the 270 mm approach into the fold station.
Reject Gate at a Bottle Fill Line
Kicks underfilled bottles into the reject chute; 245 N push at 0.5 MPa swings the gate against line backpressure without hesitation.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X270SCA the Right Cylinder?
Compare before you commit: a 20 mm MAC turns 157 N at 0.5 MPa and a 32 mm MAC 402.2 N; the 25 mm splits the pair and uses less air than the larger bore. When the valve centres, the load takes over and the piston moves - a pilot check valve or rod lock is what actually holds position. The CA pin pairs with SDB pivot brackets, and FA flange or LB foot mounts back the barrel on a 270 mm stroke; hang the work from guides, not the rod.
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 MAC25X270SCA FAQ
The bore delivers 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, and up to 50 kgf theoretically at 1.0 MPa. Supply is via 1/8" ports with M10x1.25 rod thread, over 0.15-1.0 MPa (22-145 psi).
The rolled stainless tube with its hard-chrome plated rod resists the washdown, condensation and metal dust that pit painted or bare-aluminium mini cylinders, keeping the grease-packed seal surfaces sound over long duty cycles.
