Airtac MAC Stainless Steel Mini Air Cylinder MAC32X185SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X185SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 185mm 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 MAC32X185SU
Over 185 mm of travel, this bore 32 MAC cylinder puts 402 N of push on the table at 0.5 MPa while air cushions at both ends soak up end-of-stroke shock. The body is a rolled stainless tube with aluminium covers - no tie rods to loosen - and the chrome-plated carbon-steel rod stands up to splash and outdoor dust. It runs on 0.15-1.0 MPa (22-145 psi) filtered air and cycles from 30 to 800 mm/s.
Size real duty near 240 N, keeping a reserve under the 402 N rating, and the cylinder stays inside its comfort zone for years. Mounting is direct through the U flat-end back cover, with FA flange, LB foot or SDB pivot brackets optional, and the standard piston magnet pairs with EMSG switches for position feedback.

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 MAC32X185SU Is Used
Part push-off at a CNC pallet station
Knocks finished parts off a pallet into a chute; 402 N at 0.5 MPa clears stuck chips and swarf from under the part.
Carton stop on a gravity roller spur
A 185 mm slide stop that diverts cartons on a spur line; the stainless body copes with humid warehouse air year round.
Tray transfer pusher on a wrapping line
Moves trays sideways into the film wrapper; CMSG switches confirm extend and retract on every cycle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X185SU the Right Cylinder?
A 25 mm MAC gives about 245 N at 0.5 MPa if the duty is lighter; the 40 mm bore delivers 628 N for stiffer pushes. Do not rely on this cylinder to park a load - centred valves and lost air both let the piston move, so a check valve or rod lock is the holding answer. The U flat back cover faces a plate or bracket squarely, and the built-in magnet means CMSG and EMSG switches fit off the shelf. Over 185 mm of travel, guide the load independently and shield the 12 mm rod from side forces. If the job later needs a double-rod version, the MACD shares this platform; MACJ adds adjustable cushioning and MAR brings an integrated mount.
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 MAC32X185SU FAQ
Measured on this bore: 402.2 N forward and 345.6 N retract at 0.5 MPa; 563.0 N forward and 483.8 N retract at 0.7 MPa; 82 kgf theoretical at 1.0 MPa. Air connects through 1/8" ports on the 32 mm barrel.
Yes - the rolled stainless tube with its 20 um hard-chrome plated rod tolerates rinse-down and humidity far better than painted mini cylinders, and the riveted cover design stays sealed with no tie rods to re-torque.
