Airtac MAC Stainless Steel Mini Air Cylinder MAC32X400SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X400SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 400mm 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 MAC32X400SU
The U flat-end back cover is what sets the MAC32X400SU apart: a flat machined face that bolts flush against machine plates with no knuckle in between. Behind it sits a double-acting 32 mm bore pushing 402.2 N at 0.5 MPa over a 400 mm stroke, with a variable air cushion at each end to tame the stops.
The stainless rolled barrel shrugs off splash and condensation that pit painted minis, while the 20 um hard-chrome rod resists scoring on long duty cycles. As a working figure, count on about 241 N of push at 0.5 MPa rather than the full 402 N, and the factory-fitted magnet means CMSG / DMSG / EMSG switches need no special-order piston.

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 MAC32X400SU Is Used
Fixture clamp slide
Clamps and releases automotive bracket fixtures over a 400 mm pull; about 241 N of usable push at 0.5 MPa is ample for hold-down duty.
Tool-crib drawer eject
Ejects heavy tool-crib drawers for picking; the flat U cover bolts straight to the crib frame without an intermediate bracket.
Hopper slide-gate actuator
Opens and closes a slide gate on a granulate hopper, with the variable cushion easing the gate into its seat at each end of the 400 mm travel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X400SU the Right Cylinder?
Compare 25 mm (245.3 N push at 0.5 MPa) and 40 mm (628.3 N) before committing - the 32 mm's 402.2 N covers mid-weight tooling with margin. A centred valve or dropped supply leaves the rod free to drift, so add a rod lock where a raised load must wait. The flat U face mounts directly to plates; SDB pivot, FA and LB hardware are available, and the built-in magnet pairs with CMSG / DMSG / EMSG switches from day one. Guide long 400 mm strokes externally to protect the rod from side load.
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 MAC32X400SU FAQ
Push 402.2 N and pull 345.6 N 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. It runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air, with 1/8" ports in PT (blank), G or T (NPT) thread.
The U cover presents a flat fixed face that bolts straight to machine plates or brackets, no pivot knuckle needed. Add FA flange, LB foot or SDB pivot hardware when the barrel itself needs support along the 400 mm stroke.
