Airtac MAC Stainless Steel Mini Air Cylinder MAC20X160SCMLB
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X160SCMLB is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 160mm 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 MAC20X160SCMLB
Built around a riveted stainless barrel and a hard-chrome plated rod, the MAC20X160SCMLB is a double-acting mini cylinder that runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air. At 0.5 MPa it pushes 157 N and pulls 132 N, rising to 220 N push at 0.7 MPa, so it sits comfortably in the light-assembly force class while the variable air cushion at both ends soaks up end-of-stroke shock.
Its 160 mm stroke is a standard length for the 20 mm bore, and the CM round-end back cover pairs with an LB foot bracket when you want a fixed base instead of a pivoting body. Every unit carries a built-in magnet, so CMSG, DMSG or EMSG switches clip straight on without a special piston. In practice you should budget roughly 94 N of the 157 N rating for real work at 0.5 MPa; vertically the full push force lifts about 8 kg once you apply a 2:1 margin.

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 MAC20X160SCMLB Is Used
Reject gate on a bottling line
Bolt the LB foot to the frame beside the belt and use the 157 N push at 0.5 MPa to kick under-filled bottles off at full line speed.
Bench bushing press
A small fixture press for brass bushings into housings - the 20 mm bore's 94 N working band and 160 mm stroke cover the approach and press in one cycle.
Case tab folding arm
Fold cardboard tabs on a carton sealer; the foot-mounted body resists the twisting that tab folding puts on a cylinder.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X160SCMLB the Right Cylinder?
If 157 N at 0.5 MPa overshoots your load, a 16 mm bore does the job with 100 N; when loads climb past 245 N, jump to the 25 mm bore instead. The rod is free to move whenever air vents - the cushion only softens arrival, it never locks - so hang a pilot check valve or rod lock on anything that must stay raised. The LB foot plus CM round-end cover gives a rigid base mount, and the standard magnet keeps CMSG, DMSG and EMSG sensing open to you from day one.
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 MAC20X160SCMLB FAQ
At 0.5 MPa it pushes 157 N and pulls 132 N; at 0.7 MPa that becomes 220 N push and 185 N pull, with a 32 kgf theoretical maximum at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, ports are 1/8" and the 8 mm rod carries an M8x1.25 male thread.
The variable air cushion lives in needle screws at each end: back them fully off before the first strokes, then close them gradually while cycling until the end-of-stroke knock disappears. The magnet is already fitted, so a CMSG, DMSG or EMSG switch can be added at any time.
