Airtac MAC Stainless Steel Mini Air Cylinder MAC20X50SCMLB
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X50SCMLB is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 50mm 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 MAC20X50SCMLB
A 20 mm bore, 50 mm stroke mini cylinder with LB foot brackets built in, the MAC20X50SCMLB runs double acting - air extends and retracts the rod - and both ends carry a variable air cushion. Expect 157 N of push and 131.9 N of pull at 0.5 MPa; at 0.7 MPa that becomes 219.8 N on extend. Foot mounting lets the body sit flat in a machine base without a separate bracket kit.
The riveted stainless barrel resists washdown and damp shop air far better than painted minis, and the hard-chrome rod (20 um) keeps the sealing surfaces smooth. Because the magnet is standard, CMSG / DMSG / EMSG switches mount anywhere on the barrel with no special piston. Budget for roughly 94 N of usable work at 0.5 MPa, or about 8 kg of vertical lift with a 2:1 margin - the numbers that actually size your fixture.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MAC20X50SCMLB Is Used
Case tab press
Pressing glue tabs closed on small shipping cases: 157 N at 0.5 MPa is enough for 20 mm board, and foot mounting drops the cylinder straight onto the frame.
Gate diverter
A sliding gate that routes pills between two chutes in a packaging machine: the 50 mm stroke covers the port, and dual cushions kill the clunk at each stop.
Fixture clamp row
Clamping aluminium extrusions in a welding jig: even at about 94 N of real working force per unit, four cylinders grip the profile firmly through the tack weld.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X50SCMLB the Right Cylinder?
Compare across the range: the 16 mm bore gives 100.5 N push at 0.5 MPa for lighter jobs, while the 25 mm bore reaches 245.3 N if your load grows. This foot-mounted version anchors to a flat plate; for pivoting linkage duties take the CA pivot or CM round-end cover instead. Note that a MAC holds nothing when air is cut - the piston simply drifts - so fit a rod lock or pilot check valve where a load must stay put.
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 MAC20X50SCMLB FAQ
Push at 0.5 MPa is 157 N and pull is 131.9 N. At 0.7 MPa expect 219.8 N push and 184.7 N pull, and the theoretical maximum is 32 kgf at 1.0 MPa. Supply pressure runs 0.15-1.0 MPa (22-145 psi).
The foot brackets let the cylinder bolt flat to a baseplate or machine wall, keeping the rod line aligned without fabrication. Back the cushion needle screws off on first run-up, then close them gradually until the 50 mm stroke stops smoothly at speeds up to 800 mm/s.
