Airtac MAC Stainless Steel Mini Air Cylinder MAC20X100SCMLB
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X100SCMLB is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 100mm 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 MAC20X100SCMLB
At 0.5 MPa the double-acting MAC20X100SCMLB delivers 157 N of push and 132 N of pull through an 8 mm rod, enough for gripping, gating and light lifting on a 100 mm stroke. Run it on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) and it cycles from 30-800 mm/s. For sizing, treat the working effort as roughly 94 N rather than the full 157 N rating so seals and mounts keep a healthy margin.
The stainless round barrel and hard-chrome plated rod shrug off mild corrosion and washdown, a real edge over painted-steel minis in damp or outdoor spots. Its LB foot base bolts the body down flat while the CM round-end back cover gives a tidy pivot point without extra brackets. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clip straight on to report end positions.

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 MAC20X100SCMLB Is Used
Dairy tray gate
Bolts via the LB foot beside a filling-line conveyor and swings a deflector to divert 8 kg yogurt trays, cushioned at both ends.
Bottle-line reject pusher
Kicks off-spec bottles from a rinser outfeed with 157 N of push, the CM round-end cover taking the pivot pin directly.
Small cart stop
A foot-mounted stop that catches light trolleys on a 100 mm stroke, position confirmed by a DMSG switch on the standard magnet.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X100SCMLB the Right Cylinder?
Need less force? The 16 mm bore pushes 100 N at 0.5 MPa. Need more? The 25 mm bore reaches 245 N at the same pressure. Like every MAC, this cylinder drifts freely when air is lost, so fit a pilot check valve or rod lock if the gate must stay put. The variable air cushion at both ends is tuned with the needle screws: open them on first run, then close gradually as speed rises.
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 MAC20X100SCMLB FAQ
At 0.5 MPa it pushes 157 N and pulls 132 N. At 0.7 MPa push rises to 220 N. The theoretical maximum at 1.0 MPa is 32 kgf. Working pressure spans 0.15-1.0 MPa (22-145 psi), and this version has a 100 mm stroke on a 20 mm bore with a 1/8 inch port.
The rolled stainless tube and hard-chrome 8 mm rod resist mild corrosion and rinse-down, so the body does not flake or stain in damp plants. The rod thread is M8x1.25 and the magnet comes standard for sensor fitment.
