Airtac MAC Stainless Steel Mini Air Cylinder MAC32X50SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X50SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 50mm 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 MAC32X50SU
A 32 mm bore with a short 50 mm stroke in AirTAC's riveted round-body mini range, the MAC32X50SU is double acting - air extends the rod and air retracts it - with a variable air cushion at both ends. Rated 402 N push and 346 N pull at 0.5 MPa (563 N at 0.7 MPa), it pays to plan around 241 N of usable working force at 0.5 MPa rather than the full rating, which keeps the cylinder cool and extends seal life.
The stainless-steel barrel with its hard-chrome plated 12 mm rod takes mild corrosion and washdown in stride - a genuine edge over painted-steel minis in damp, food or outdoor spots. The U flat-end back cover bolts to fixed plates with no extra bracket, and since the magnet is standard, CMSG / DMSG / EMSG switches clip straight on. On first start-up, back the cushion needle screws off and open them gradually.

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 MAC32X50SU Is Used
Jig clamp on PCB test benches
About 241 N of usable push at 0.5 MPa seats circuit boards into test fixtures firmly, and the 50 mm stroke clears the loading hand quickly.
Reject kickers on bottling lines
A short, cushioned 50 mm flick pushes underweight bottles off the conveyor without cracking labels, and the stainless barrel handles daily hose-down.
Vial cap press in lab automation
The compact 32 mm round body fits tight analytical-instrument frames, pressing septum caps onto sample vials with a repeatable 402 N peak force.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X50SU the Right Cylinder?
Cross-check size: the 25 mm bore manages 245 N at 0.5 MPa and the 40 mm bore reaches 628 N, so 32 mm sits in the middle for short jigs and clamps. Operating window is 0.15-1.0 MPa (22-145 psi) with speeds of 30-800 mm/s, and the 50 mm stroke is a stock length, so nothing here is made to order. Like any double-acting mini, the rod simply coasts when air is lost or the valve centres - add a rod lock or pilot check valve where a load must stay parked. FA flange, LB foot or SDB pivot brackets plus I / Y rod knuckles round out the mounting kit.
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 MAC32X50SU FAQ
At 0.5 MPa the cylinder pushes 402 N and pulls 346 N; at 0.7 MPa that becomes 563 N push and 484 N pull. The theoretical maximum at 1.0 MPa works out to 82 kgf. Ports are 1/8", the rod is 12 mm with an M10x1.25 male thread, and speed spans 30-800 mm/s within a 0.15-1.0 MPa (22-145 psi) supply.
No - every MAC32X50SU ships with the magnet already fitted as standard on the piston. CMSG, DMSG or EMSG switches then clamp anywhere along the stainless tube for end-of-stroke or mid-stroke signalling, straight from the catalogue without a special-order build.
