Airtac MAC Stainless Steel Mini Air Cylinder MAC32X105SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X105SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 105mm 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 MAC32X105SU
A 105 mm stroke in AirTAC's riveted round-body format, the MAC32X105SU is double acting with a variable air cushion at both ends. Its stainless barrel and hard-chrome plated rod laugh off washdown and damp shops where painted minis corrode, while the cushion needle screws bleed off end-of-stroke shock so faster cycling never hammers the covers. At 0.5 MPa this bore pushes 402 N, so budget roughly 241 N for real work and you keep solid margin for friction and wear.
The U flat-end back cover bolts straight to a fixed plate without adapter brackets, and FA flange or LB foot options cover other frames. The magnet comes standard, so CMSG, DMSG or EMSG switches clamp on for end-of-stroke signalling with no special piston. Speed range is 30-800 mm/s across 0.15-1.0 MPa (22-145 psi); over 105 mm of travel, guide the load so side forces stay off the 12 mm rod.

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 MAC32X105SU Is Used
Tray eject on a thermoformer
Pushes formed trays clear of a shallow die in one move; 402 N at 0.5 MPa is ample and the 105 mm stroke fully clears the tool edge.
Carton push-off at a case packer
Sweeps finished cartons from a conveyor discharge lane, with the variable cushion absorbing the stop against a fixed plate.
Sliding gate on an assembly diverter
Drives a gate that sends parts between two chutes; the U flat-end cover bolts flush to the gate frame without brackets.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X105SU the Right Cylinder?
Compare before you commit: bore 25 reaches only 245 N at 0.5 MPa while bore 40 delivers 628 N, so the 32 mm sits mid-class for pushing jigs or ejected parts. One caveat - nothing holds the rod when air drops or the valve centres, since the piston drifts, so fit a rod lock or pilot check valve where a raised load must wait. With 105 mm of travel any lateral misalignment multiplies, so couple through an I or Y knuckle or align the tooling closely.
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 MAC32X105SU FAQ
Double-acting output at 0.5 MPa is 402 N extending and 346 N retracting; at 0.7 MPa it rises to 563 N and 484 N. The theoretical ceiling is 82 kgf at 1.0 MPa. Operating window is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed 30-800 mm/s.
The U flat-end back cover takes a fixed bolt directly; add an FA flange or LB foot for frame mounting. The built-in magnet works with CMSG, DMSG and EMSG switches out of the box. Keep side load low - the 12 mm hard-chrome rod handles guidance but not deliberate bending.
