Airtac MAC Stainless Steel Mini Air Cylinder MAC32X175SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X175SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 175mm 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 MAC32X175SU
Round-bodied and rolled tight, the MAC32X175SU pairs a stainless-steel barrel with a 12 mm hard-chrome plated rod, so damp corners and occasional washdown do not eat the tube the way they ruin painted-steel minis. It is double acting - air extends and retracts the rod - with a variable air cushion at both ends, running on filtered air at 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s. The 32 mm bore pushes 402 N and pulls 346 N at 0.5 MPa, rising to 563 N of push at 0.7 MPa.
Back both cushion needle screws off before the first stroke, then close them gradually to tame end-of-stroke shock - that is what lets you run faster or move heavier jig plates without hammering the aluminium covers. The U flat-end back cover bolts straight to a fixed plate with no bracket to fabricate, and the built-in magnet ships as standard, so CMSG, DMSG or EMSG switches clip on for signalling. For lift duty, 402 N equals about 41 kg of vertical pull, which is roughly 20 kg of real lifting once you keep a 2:1 margin.

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 MAC32X175SU Is Used
Carton push-off arm
Kicks filled cartons sideways off a roller conveyor into a chute; the 175 mm stroke crosses a 150 mm lane and 402 N of push at 0.5 MPa beats lane friction with room to spare.
Swing clamp on a machining fixture
Pulls a clamp arm down on aluminium blanks between cuts; the U flat-end cover bolts flush inside the fixture body and the cushion stops the arm without a clunk.
Hopper slide gate
Opens and closes the slide gate under a pellet hopper once per batch; the stainless barrel tolerates the damp, dusty air around the outlet far better than a painted mini.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X175SU the Right Cylinder?
At 402 N of push the 32 mm bore sits between the 25 mm (245 N at 0.5 MPa) and the 40 mm (628 N at 0.5 MPa) - step up only when load plus friction passes the roughly 240 N you should plan as usable work. The piston does not hold position: if air drops or the valve centres, the load can drift the rod, so fit a rod lock or pilot check valve whenever the 175 mm stroke parks under load. With 175 mm of unsupported reach, keep the driven load guided externally so side forces never bend the 12 mm rod. The U flat-end back cover bolts direct to a plate; FA flange, LB foot or SDB pivot hardware and I or Y rod knuckles order alongside if the frame needs them.
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 MAC32X175SU FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa push reaches 563.0 N, with a theoretical maximum of 82 kgf at 1.0 MPa. Bore 32 ports at 1/8", the 12 mm rod threads M10x1.25 male, and PT (blank), G or NPT threads can be ordered. Supply sits at 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, temperature -20 to +70 C.
No. Every MA-series cylinder ships with the magnet built in as standard, so CMSG, DMSG or EMSG switches mount straight onto the stainless barrel for end-of-stroke or mid-stroke signalling - no special-order piston, no waiting.
