Airtac MAC Stainless Steel Mini Air Cylinder MAC25X180SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X180SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 180mm 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 MAC25X180SCA
Where the load swings rather than slides, the CA pivot back cover of the MAC25X180SCA pins straight into a clevis or link arm, so the 180 mm stroke tracks a curved path without extra brackets. The double acting cylinder delivers 245.3 N at 0.5 MPa and runs on a variable air cushion at both ends, tunable across 30-800 mm/s.
Inside, a stainless-steel barrel is rolled up with aluminium covers and a stainless block for a sealed riveted body, while the 10 mm hard-chrome rod stands up to damp air. Because 245.3 N at 0.5 MPa equals about 25 kg of raw lift, budget roughly 12 kg vertical for a comfortable 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 MAC25X180SCA Is Used
Chute diverter on a grain conveyor
The CA pivot swings a diverter flap through its arc while 245 N at 0.5 MPa seats it firmly against dust seals.
Clamp arm on a welding jig
245.3 N of push clamps steel brackets for tack welding; the variable cushion keeps the arm from bouncing at the end of its 180 mm sweep.
Lift gate on a small hopper
Roughly 12 kg of vertical capacity opens a light hopper gate, with the riveted stainless body shrugging off grain dust and damp air.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X180SCA the Right Cylinder?
Choose bore 25 (245.3 N push at 0.5 MPa) when bore 20 at 157 N falls short but bore 32 at 402 N is oversized. The CA cover handles pivot duty; if the frame needs fixed mounting instead, FA flange or LB foot brackets fit the same body. It never holds position on lost air - the piston coasts until the load stops it, so specify a rod lock or pilot check valve whenever a part must stay parked. At 180 mm on a 10 mm rod, keep thrust in line with the bore axis and guide any side load externally. CMSG, DMSG or EMSG switches snap onto the standard magnet for end-of-stroke signals.
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 MAC25X180SCA FAQ
Push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N and pull 288.5 N at 0.7 MPa; about 50 kgf theoretical at 1.0 MPa. Air ports are 1/8" and the rod thread is M10x1.25. Speed 30-800 mm/s within 0.15-1.0 MPa (22-145 psi).
The CA back cover carries the pivot pin at the round-end, so swing arms, flap gates and linkages articulate naturally. Pair it with an SDB pivot bracket when the base also needs to swivel, and fit I or Y knuckles on the M10x1.25 rod for the load side.
