Airtac MAC Stainless Steel Mini Air Cylinder MAC40X450SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X450SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 450mm 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 MAC40X450SU
A flat-ended U back cover distinguishes the MAC40X450SU, letting the 40 mm cylinder butt directly against a shoulder or fixture plate. Under the cover sits AirTAC's riveted stainless round barrel with a hard-chrome plated 16 mm rod, double acting, and cushioned by variable air screws at both stroke ends.
At 0.5 MPa this bore pushes 628.3 N and pulls 527.8 N; halve the 64 kg lift equivalent and you get about 32 kg of vertical lifting with a 2:1 margin built in. Running to 800 mm/s, the 450 mm stroke finishes soft on the cushion instead of slamming the covers, and the standard magnet picks up CMSG / DMSG / EMSG switches.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MAC40X450SU Is Used
Clamp-and-present fixture on a CNC lathe
Butts flush to the fixture plate via the U cover; 628 N at 0.5 MPa presents bushings to the operator cycle after cycle.
Divert gate on a parcel sorter
Kicks small parcels onto a chute across a 450 mm span; the variable cushion lands the gate quietly at high cycle rates.
Stack lift on a tray erector
Raises a 30 kg tray stack - inside the 32 kg 2:1 vertical margin - and cushions the descent at both stroke ends.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X450SU the Right Cylinder?
Force ladder: the 32 mm bore delivers 402.2 N and the 50 mm bore 981.3 N push at 0.5 MPa, framing the 40 mm choice for this 450 mm travel. Note a plain MAC cannot hold a load on lost air - the rod drifts - so use a rod lock or pilot check valve for suspended loads. The flat U cover bolts flush to fixtures; FA flange, LB foot or SDB pivot mount it otherwise. With 450 mm of rod exposed, minimise side load and support the load on external guides. Port is 1/8", thread PT (blank), G or NPT.
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 MAC40X450SU FAQ
Push 628.3 N, pull 527.8 N at 0.5 MPa; push 879.6 N, pull 738.9 N at 0.7 MPa; 128.1 kgf theoretical maximum at 1.0 MPa. Double acting with variable air cushion at both ends, 30-800 mm/s, 0.15-1.0 MPa (22-145 psi) operating, 1.5 MPa (215 psi) proof, 1/8" ports, M12x1.25 rod thread on a 16 mm rod.
The rolled stainless tube and 20 um hard-chrome rod resist rust in rain, dust and washdown where painted minis corrode, and the riveted covers keep the seal intact. The magnet is fitted as standard, so position feedback with CMSG / DMSG / EMSG switches needs no special order.
