Airtac MAC Stainless Steel Mini Air Cylinder MAC32X475SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X475SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 475mm 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 MAC32X475SCM
A rounded CM end cover turns the MAC32X475SCM into a smooth-nosed pusher for chutes and diverter paths, mounted on a 475 mm stroke with 402.2 N of push at 0.5 MPa. Inside sits the familiar MA recipe: stainless round barrel riveted to aluminium covers, 12 mm hard-chrome rod, and a grease-storing two-way piston seal that keeps lubrication where it counts.
Air drives the rod both directions and a variable cushion at each end absorbs the arrival shock of heavier payloads - 563.0 N is available if you raise supply to 0.7 MPa. Size continuous work to about 241 N, which matches lifting roughly 20 kg vertically with a 2:1 margin, and count on the standard magnet to trigger CMSG, DMSG or EMSG switches along the travel.

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 MAC32X475SCM Is Used
Case ramp pusher
Rounds finished 12-pack cases down a transfer ramp; the CM nose slides against case edges without snagging, driven by 402 N at 0.5 MPa.
Recycling sorter actuator
Diverts PET bottles between collection bins in a material-recovery line, cycling the 475 mm stroke at 600 mm/s all shift.
Machine-tool chip door
Opens the sliding chip enclosure door on a CNC lathe; the round stainless barrel tolerates coolant splash and swarf-laden air.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X475SCM the Right Cylinder?
Force ladder at 0.5 MPa push: 245.3 N on the 25 mm bore, 402.2 N here at 32 mm, 628.3 N on the 40 mm bore. If your pusher must never stall above roughly 240 N of drag, this bore is the economical pick; oversize to 40 mm for headroom. Remember the piston is free-floating on air - a centred valve does not park it, so a rod lock or pilot check valve is the fix for held loads.
The CM round-end nose suits chute and ramp work; SDB pivot brackets or LB feet adapt the body to the frame. Ports are 1/8" per cover and the 475 mm travel calls for straight alignment - misalignment over a stroke this long shows up as rod seal wear, so check couplings run true.
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 MAC32X475SCM FAQ
At 0.5 MPa: 402.2 N push, 345.6 N pull. At 0.7 MPa: 563.0 N push, 483.8 N pull. Maximum theoretical force is 82 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), medium filtered air to 40 um.
The rounded back cover presents a smooth surface that will not snag cartons, straps or chutes passing close to the cylinder tail, and it mounts to pivot brackets without adaptors. Combined with the stainless riveted barrel it also wipes clean easily in dusty or splashy areas.
