Airtac MAC Stainless Steel Mini Air Cylinder MAC25X55SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X55SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 55mm 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 MAC25X55SCA
Short, direct and pivot-ready, the MAC25X55SCA puts 245.3 N of push at 0.5 MPa behind a 55 mm stroke. It is double acting with a variable air cushion at each end, and the CA pivot rear cover accepts a clevis pin so the cylinder can follow a swinging link. The 55 mm stroke sits well inside the 500 mm standard range for bore 25, so it is a catalogue item.
The rolled stainless barrel with hard-chrome rod shrugs off coolant splash and washdown in a way painted minis cannot, and the aluminium covers keep it light. Rated across 0.15-1.0 MPa (22-145 psi) with speeds of 30-800 mm/s, this bore lifts about 25 kg of dead weight at full push, or plan on 12.5 kg with a 2:1 margin. The built-in magnet is standard, letting CMSG, DMSG or EMSG switches report position without ordering a special 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 MAC25X55SCA Is Used
Drill-jig clamp
Clamps a bracket into a drill jig with a quick 55 mm clamp action, cushioned to settle the part without bounce.
Vision-nest presenter
Pushes a part into a camera nest and the standard magnet trips a CMSG switch to confirm full forward seat.
Chute diverter flap
Swings a diverter flap on its pivot pin to route small castings between two collection chutes.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X55SCA the Right Cylinder?
At 0.5 MPa the smaller bore 20 MAC gives 157.0 N and the larger bore 32 gives 402.2 N, so the 25 mm bore fits medium-duty clamps and pushes in the 150 to 240 N band. Match FA flange, LB foot or SDB pivot mounting to the frame and an I or Y rod knuckle to the load. The cylinder does not lock position: with the valve centred or air off the rod drifts, so fit a rod lock or pilot check valve 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 MAC25X55SCA FAQ
Push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N at 0.7 MPa; theoretical maximum 50.0 kgf at 1.0 MPa. Ports are 1/8", the rod is 10 mm with M10x1.25 male thread.
No, every MAC cylinder carries the magnet as standard. CMSG, DMSG and EMSG switches drop onto the barrel straight away, with no special-order piston and no delay.
