Airtac MAC Stainless Steel Mini Air Cylinder MAC32X180SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X180SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 180mm 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 MAC32X180SU
A 32 mm bore working through 180 mm of stroke gives 402 N of push at 0.5 MPa, double acting and fitted with a variable air cushion at both ends so the load settles instead of hammering the covers. The round stainless barrel is rolled onto aluminium covers and a stainless block, a riveted pack that tolerates washdown and humid plant air far better than painted minis. Supply pressure runs 0.15-1.0 MPa (22-145 psi) and speed covers 30-800 mm/s.
In practice, plan real work at about 241 N - six tenths of the 402 N rating - and the cylinder will live a long service life. The U flat-end back cover bolts straight onto a fixed plate without extra brackets, and because the magnet is built in as standard, CMSG, DMSG or EMSG switches drop on whenever end-of-stroke signalling is needed.

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 MAC32X180SU Is Used
Bottling line gate diverter
Swings a 180 mm divert gate across a PET bottle conveyor; 402 N at 0.5 MPa holds the gate seated even against moving containers.
Carton stack ejector
Pushes the bottom sleeve from a carton magazine into a forming station; the cushioned ends let it cycle fast without jarring the frame.
Slide feed on a small press
Feeds a blank 180 mm into a stamping die; tune the needle screws so the part lands square instead of slammed.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X180SU the Right Cylinder?
Step down to a 25 mm MAC if 245 N at 0.5 MPa covers the job, or up to the 40 mm bore for 628 N. Neither option holds position by itself - vent the line and the rod drifts - so pair a pilot check valve or rod lock with any clamped load. Fixed mounting comes naturally to the U flat back cover; add an FA flange, LB foot or SDB pivot bracket where the frame demands it, and the standard magnet accepts CMSG or DMSG switches. With 180 mm of stroke, keep side loads low and support the 12 mm rod so it does not bend.
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 MAC32X180SU FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa those rise to 563.0 N push and 483.8 N pull, with a theoretical maximum of 82 kgf at 1.0 MPa. The 12 mm hard-chrome rod threads M10x1.25 and air connects through 1/8" ports, standard for this bore.
Back both needle screws fully off before start-up, run the cylinder at low speed, then close each screw gradually until the load stops hitting the covers hard. Keep cycles within 30-800 mm/s; the variable cushion is a damper, not a position lock.
