Airtac MAC Stainless Steel Mini Air Cylinder MAC40X450SCMLB
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X450SCMLB 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 MAC40X450SCMLB
Foot mounting comes built in on the MAC40X450SCMLB: the same 40 mm stainless round barrel and hard-chrome 16 mm rod as the rest of the MAC line, finished with a CM round-end back cover and LB foot plates so it bolts flat onto a machine base without extra brackets. Double acting, with a variable air cushion at each end taming the 450 mm stroke.
Expect 628.3 N push and 527.8 N pull at 0.5 MPa, rising to 879.6 N at 0.7 MPa. Planning around 377 N of real working force - roughly 0.6 of the push rating - leaves headroom for pressure dips. The stainless barrel handles damp and washdown zones, and the magnet is standard equipment 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 MAC40X450SCMLB Is Used
Pallet-corner squaring before strapping
Squares misaligned pallet loads on a strapper infeed; LB feet anchor the cylinder to the frame for a stable 628 N push.
Fork presence flag in a charging bay
Detects fork truck arrival by sweeping a flag across the aisle; the variable cushion absorbs the 450 mm travel at speed.
Diverter gate at a concrete batching plant
Opens a small aggregate slide in dust and rain; 377 N of working force at 0.5 MPa moves a lightly loaded gate, and the stainless barrel shrugs off the weather.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X450SCMLB the Right Cylinder?
Compare by force: the 32 mm bore offers 402.2 N at 0.5 MPa and the 50 mm bore 981.3 N, so 40 mm suits mid-weight pushes over 450 mm of travel. If the load must stay put on air loss, remember a plain MAC drifts - a rod lock or pilot check valve does the holding instead. Foot mounting spreads the thrust into the base, but a 450 mm rod still needs external guiding against side loads. G or NPT threads can replace the standard PT (blank).
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 MAC40X450SCMLB 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; up to 128.1 kgf theoretical at 1.0 MPa. Double acting with a variable air cushion at both ends, speed 30-800 mm/s, pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), 1/8" ports, 16 mm hard-chrome rod with M12x1.25 thread, -20 to +70 C.
LB foot plates let the cylinder lie flat on a frame and take thrust through the base, which avoids bracket stacking on long 450 mm strokes. Together with the CM round back cover you can still add SDB pivot brackets, FA flanges or I and Y rod knuckles, and the standard magnet accepts CMSG, DMSG or EMSG switches.
