Airtac MAC Stainless Steel Mini Air Cylinder MAC40X450SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X450SCM 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 MAC40X450SCM
Built around a 40 mm stainless tube with a hard-chrome 16 mm rod, the MAC40X450SCM finishes in a CM round-end back cover, a shape that drops onto fixed and pivoting brackets without adapter plates. Air drives the piston both ways - double acting - and a variable air cushion at each end soaks up end-of-stroke shock on the long 450 mm travel.
The bore delivers 628.3 N push and 527.8 N pull at 0.5 MPa. In round figures that is a 64 kg vertical-lift equivalent, or about 32 kg when you keep a 2:1 margin, an easy way to match real part weights. Washdown and humid workshops suit the stainless barrel, and every unit carries a standard magnet for 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 MAC40X450SCM Is Used
Gate actuation on a bakery oven line
Slides a heat-shield gate 450 mm clear of trays; the CM round cover suits the fixed bracket on the oven frame.
Lab mixer head lift
Raises a 30 kg mixing head vertically - within the 32 kg 2:1 margin at 0.5 MPa - with cushioned stops at both ends.
Indexing stop on a chain conveyor
Drops and lifts a stop blade between chain flights; 628 N push at 0.5 MPa holds the station against light back-pressure.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X450SCM the Right Cylinder?
Sizing check: step down to the 32 mm bore for 402.2 N at 0.5 MPa or up to the 50 mm bore for 981.3 N - the 40 mm sits between them for this 450 mm stroke. When the valve centres or air drops, a plain MAC drifts rather than locks; fit a rod lock or pilot check valve where the load must stay. The round CM cover works with FA flange, LB foot or SDB pivot brackets, I and Y rod knuckles are available, and ports are 1/8" with PT (blank), G or NPT options. Long unsupported rods bend under side load, so guide the load on its own rails.
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 MAC40X450SCM FAQ
At 0.5 MPa: 628.3 N push, 527.8 N pull. At 0.7 MPa: 879.6 N push, 738.9 N pull. Theoretical ceiling is 128.1 kgf at 1.0 MPa. It is double acting with variable air cushioning, runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, proof tested at 1.5 MPa (215 psi), with 1/8" ports and an M12x1.25 rod thread.
No. The variable air cushion only softens the last part of travel; with air off or the valve centred the piston drifts freely. Fit a rod lock or pilot check valve when the 450 mm stroke must hold position, and back the cushion needle screws off on first run before closing them gradually.
