Airtac MAC Stainless Steel Mini Air Cylinder MAC32X500SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X500SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 500mm 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 MAC32X500SU
A flat U back cover on this 500 mm stroke cylinder bolts directly against machine faces, turning 0.5 MPa supply into 402.2 N of push and 345.6 N of pull along the full travel - hung vertically that equals about 41 kg of lift, or roughly 20 kg with a 2:1 margin. Both ends carry a variable air cushion, adjustable with needle screws, so 800 mm/s moves stop without a bang.
The double-acting piston needs air on both strokes; with no spring return, feed air to the rod side for retraction. The stainless-steel barrel and hard-chrome plated 12 mm rod tolerate outdoor humidity and food-plant washdown, and with the standard magnet a CMSG or DMSG switch reports position over the whole 500 mm run.

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 MAC32X500SU Is Used
Case squaring push
Square cases against a stop before taping; the flat U cover bolts flush to the frame rail and 402 N aligns the stacked flaps.
Lid press-down station
Press snap-on lids home across 500 mm of closing travel on an assembly line, cushion-controlled at both ends of the stroke.
Slide extension drive
Extend a tool slide on a grinding machine; the stainless barrel copes with coolant splash near the wheel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X500SU the Right Cylinder?
If your job needs under 245.3 N of push, the 25 mm bore costs less; over 628.3 N, step up to 40 mm. This 32 mm bore covers the middle ground with 402.2 N at 0.5 MPa and 563.0 N at 0.7 MPa, and its U cover clamps straight to a frame member without brackets.
Long strokes amplify rod bending, so support the load on its own guides and consider an I or Y rod knuckle at the rod end. Do not rely on this cylinder to park a load: when the valve centres or air fails, the piston drifts freely, so a rod lock or pilot check valve is needed for held positions. FA flanges, LB feet and SDB pivots adapt the mount if the frame layout changes.
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 MAC32X500SU FAQ
402.2 N push and 345.6 N pull at 0.5 MPa; 563.0 N push and 483.8 N pull at 0.7 MPa; 82 kgf theoretical maximum at 1.0 MPa. Bore 32 mm, rod 12 mm (M10x1.25 thread), 1/8 inch ports, 0.15-1.0 MPa (22-145 psi) working pressure, 30-800 mm/s speed, 500 mm stroke.
Only the back cover differs: U is a flat end face for direct bolting to a plate, CA ends in a pivot eye, CM in a round boss. Inside, all three share the same double-acting piston, variable cushions, stainless barrel and standard magnet - so any CMSG, DMSG or EMSG switch works across the range.
