Airtac MAC Stainless Steel Mini Air Cylinder MAC32X135SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X135SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 135mm 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 MAC32X135SU
With a 135 mm stroke on a 32 mm bore, this MAC generates 402.2 N of push and 345.6 N of pull at 0.5 MPa, rising to 563 N push at 0.7 MPa. Air drives the rod in both directions and a variable air cushion at each end lets you tune out end-of-stroke shock, so faster cycles up to 800 mm/s stay gentle on the covers.
The riveted stainless barrel and hard-chrome plated 12 mm rod shrug off damp air and mild washdown, an edge painted minis lose quickly. Keep real work around 241 N - roughly 60 percent of the push figure - and the cylinder holds a comfortable margin all day. The U flat-end back cover bolts straight to a fixed plate with no bracket, and the built-in magnet accepts CMSG, DMSG or EMSG switches as shipped.

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 MAC32X135SU Is Used
Carton divert arm
A push arm that swings cartons off a snack-food conveyor at up to 800 mm/s, with the cushion absorbing the divert stop and the stainless barrel surviving daily wipe-down.
Welding fixture clamp
Clamping sheet-metal panels against a jig in a fabrication cell, where 402 N at 0.5 MPa holds the part firmly while the welder runs its pass.
Lab elevator platform
Raising and lowering a 20 kg sample tray between a steriliser and a packing bench, sized with a 2:1 margin on the 41 kgf theoretical lift.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X135SU the Right Cylinder?
Size between neighbours: the 25 mm bore offers 245.3 N push at 0.5 MPa and the 40 mm bore 628.3 N, so this 32 mm size is the middle choice when 245 N is short and 628 N is oversized. The supply window runs 0.15-1.0 MPa (22-145 psi) on air filtered to 40 um. Note that a plain MAC releases its load the moment air drops - the air cushion is not a lock - so spec a rod lock or pilot check valve where position must be held. FA flange, LB foot and SDB pivot brackets complement the U flat-end cover, and ports are 1/8". Across a 135 mm stroke, avoid side loads or add external guiding to protect the 12 mm rod.
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 MAC32X135SU FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa push rises to 563.0 N and pull to 483.8 N. The theoretical maximum at 1.0 MPa is 82 kgf. Supply is 0.15-1.0 MPa (22-145 psi) and the rod is double-acting in both directions.
Both ends carry a variable air cushion tuned by needle screws. On first run, back the needles fully off, then close them gradually until end-of-stroke impact disappears. With the cushion set you can run anywhere in the 30-800 mm/s speed range without hammering the covers.
