Airtac MAC Stainless Steel Mini Air Cylinder MAC32X255SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X255SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 255mm 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 MAC32X255SCA
With a 255 mm stroke on a 32 mm bore, the MAC32X255SCA reaches across wide fixtures while staying a compact round-body mini cylinder, its stainless tube and aluminium covers rolled into one sealed unit. Double acting throughout, it pushes 402.2 N and pulls 345.6 N at 0.5 MPa, rising to 563.0 N of push at 0.7 MPa, with a variable air cushion at each end.
The CA pivot back cover swings in linkages without extra hardware, and the built-in magnet ships as standard so CMSG, DMSG and EMSG switches drop straight on. Budgeting around 241 N of working force at 0.5 MPa, roughly 60 percent of the rating, keeps the cylinder out of stall on clamping and diverting jobs. The cushion needles open the door to faster cycles, up to 800 mm/s, without end-of-stroke damage.

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 MAC32X255SCA Is Used
Pallet-gate swing on a picking line
The CA pivot suits a linkage that swings a safety gate across a pallet lane; 402 N at 0.5 MPa moves it briskly.
Tool-slide advance on a tube-bending machine
A 255 mm stroke feeds the mandrel while about 241 N of working force seats the tool against spring drag.
Stacked-carton aligner on a strapper infeed
CMSG sensors log each stroke as the cylinder squares a column of boxes before strapping.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X255SCA the Right Cylinder?
Compare the MAC25 at 245.3 N and the MAC40 at 628.3 N, both at 0.5 MPa, before settling on this 32 mm mid-point. The extra 5 mm of stroke over a 250 mm build can clear tooling interference, and both are standard for this bore. Long strokes amplify side load, so support the load on an external guide and consider a rod knuckle. Where a station must stay put with the valve off, add a rod lock or pilot check valve, since the piston drifts freely without air. Mounts include FA flange, LB foot and SDB pivot bracket in addition to the CA pivot cover, with supply at 0.15-1.0 MPa (22-145 psi).
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 MAC32X255SCA FAQ
It delivers 402.2 N push and 345.6 N pull at 0.5 MPa, 563.0 N push and 483.8 N pull at 0.7 MPa, and up to 82 kgf theoretically at 1.0 MPa. The 12 mm rod carries an M10x1.25 thread, ports are 1/8", and speed spans 30-800 mm/s.
No, the magnet is built in as standard on this cylinder, so CMSG, DMSG and EMSG switches mount directly on the barrel for end-of-stroke or mid-stroke position signals.
