Airtac MAC Stainless Steel Mini Air Cylinder MAC32X25SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X25SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 25mm 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 MAC32X25SCA
A riveted round-body mini cylinder built around a 32 mm stainless barrel, the MAC32X25SCA runs double acting with a variable air cushion at both ends and a 25 mm stroke. At 0.5 MPa it pushes 402 N and pulls 346 N, enough muscle for clamping and short-jog tasks on packaging and assembly machinery.
The CA pivot back cover accepts a pivot pin directly, so swinging links and lever arms mount without adaptor plates. Keep real working force near 241 N - roughly 60% of the 0.5 MPa push rating - and it will hold cycle rates across the full 30-800 mm/s speed range. The built-in magnet is standard, so CMSG, DMSG or EMSG switches clip on without 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MAC32X25SCA Is Used
Lid press station
Pressing snap-on caps onto detergent bottles on a packaging line, where 402 N at 0.5 MPa seats the lid and the 25 mm stroke keeps the station footprint small.
Bracket clamp fixture
Clamping aluminium brackets against a drill jig in a small machining cell; the CA pivot links the cylinder to a swing clamp arm.
Conveyor gate kicker
Kicking cartons off a transfer conveyor into a reject chute, with the variable cushion absorbing the stop at each end of the 25 mm throw.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X25SCA the Right Cylinder?
Between bores: the 25 mm MAC delivers about 245 N at 0.5 MPa and the 40 mm bore reaches 628 N, so 32 mm at 402 N sits in the middle for medium clamp loads. If the valve centres or air drops, the rod will drift - a plain cylinder does not hold position, so add a rod lock or pilot check valve for held loads. With the CA pivot cover fitted you can hang the cylinder on a swing link; add LB foot or FA flange hardware if one end needs fixing, and order the G or T suffix for BSPP or NPT ports instead of PT.
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 MAC32X25SCA FAQ
At 0.5 MPa the 32 mm bore pushes 402 N and pulls 346 N; at 0.7 MPa that rises to 563 N push and 484 N pull. The theoretical maximum at 1.0 MPa is 82 kgf. Working pressure spans 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi).
Both ends carry a variable air cushion with adjustable needle screws. Back the screws fully open before the first stroke, run the cylinder at low speed, then close them gradually until end-of-stroke shock disappears. Keep travel between 30 and 800 mm/s.
