Airtac MAC Stainless Steel Mini Air Cylinder MAC50X450SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X450SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 450mm stroke, 1/4" 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 MAC50X450SCA
Nearly the full 500 mm standard travel of the 50 mm bore is on offer here - 450 mm of double-acting stroke with 981.3 N of push and 880.8 N of pull at 0.5 MPa. The riveted stainless round barrel and hard-chrome plated rod keep corrosion out of damp, dusty or outdoor frames, and a variable air cushion at both ends tames the momentum a long stroke builds at up to 800 mm/s.
For sizing, treat 589 N as the working push at 0.5 MPa (about 60 percent of rating), which lifts roughly 50 kg vertically with a 2:1 margin. Turn the pressure up to 0.7 MPa and push climbs to 1373.8 N. The CA pivot back cover pairs naturally with clevis or SDB mounts on linkages, and the standard magnet accepts CMSG, DMSG or EMSG switches for mid-stroke position feedback.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MAC50X450SCA Is Used
Crate elevator gate lift
Raises the counterweighted gate of a bottling-crate elevator; the 450 mm stroke opens the full gate in one pull and 589 N of usable force balances the linkage.
Telescoping conveyor extend arm
Extends the roller section of a mobile telescoping conveyor in a parcel depot, where the CA pivot lets the arm follow the hinge arc without binding.
Damper sweep on a lab scrubber duct
Swings a damper blade across a laboratory scrubber duct; the stainless barrel tolerates the humid exhaust and the cushion stops the blade from chattering home.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X450SCA the Right Cylinder?
The 450 mm stroke stays inside the 500 mm standard ceiling for bore 50, so this is a catalogue length rather than a custom build. Compare neighbours: bore 40 gives 628.3 N push at 0.5 MPa, bore 63 gives 1557.9 N. Long strokes invite side load - guide the load on rollers or rails instead of loading the 16 mm rod sideways, and check rod buckling against the datasheet for heavy compressive work. Lost air means a drifting piston, so add a rod lock or pilot check valve where a gate must stay parked. Operating window is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s; port 1/4", rod thread M14x1.5, with G or NPT selectable as a specification.
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 MAC50X450SCA FAQ
Push 981.3 N and pull 880.8 N at 0.5 MPa; push 1373.8 N and pull 1233.1 N at 0.7 MPa; theoretical peak 200.1 kgf at 1.0 MPa. Stroke is 450 mm against a 500 mm standard maximum for bore 50, with a 1/4" port and M14x1.5 rod thread.
Yes. The magnet is built into the piston as standard, so CMSG, DMSG or EMSG switches clamp onto the stainless barrel at any point and signal mid-stroke or end-of-stroke without a special-order piston. The switches report position only - they do not hold the load, which still needs a rod lock or pilot check valve.
