Airtac MAC Stainless Steel Mini Air Cylinder MAC20X160SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X160SCM 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 MAC20X160SCM
A wide 160 mm travel wrapped in a slim 20 mm barrel: air drives the rod both ways at up to 800 mm/s, with a variable air cushion at each end soaking up the arrival. Push force is 157.0 N at 0.5 MPa, about 16 kgf, climbing to 219.8 N when the supply reaches 0.7 MPa. The riveted stainless tube, chrome-plated 20 um rod and rolled aluminium covers give a round body that shrugs off washdown splashes.
For day-to-day sizing, count on near 94 N of real push at 0.5 MPa; that thrust corresponds to lifting roughly 8 kg vertically once a 2:1 margin is applied. The CM round-end back cover supplies a pivoting rod eye, so linkages connect directly without extra knuckles, and the standard piston magnet lets a CMSG, DMSG or EMSG switch read position anywhere along the stroke.

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 MAC20X160SCM Is Used
Reject arm on a filler line
Sweeping a misfilled bottle off the lane over 160 mm - the pivot eye on the CM cover ties straight into the sweep arm.
Drawer latch actuation
Driving a heavy-duty drawer latch across a long throw; the cushion kills the slam as the latch seats.
Battery cover slide
Sliding a forklift battery compartment cover 160 mm; about 94 N of usable force at 0.5 MPa moves the panel smoothly.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X160SCM the Right Cylinder?
Between the 16 mm bore (100.5 N push at 0.5 MPa) and the 25 mm bore (245.3 N), this 20 mm option lands at 157.0 N push and 131.9 N pull for the 160 mm stroke. Keep side forces off the 8 mm rod over such a long travel - use external guides or an SDB pivot bracket to hold the thrust axial. Air pressure alone cannot park the rod: with the supply removed or the valve in neutral the piston creeps, so specify a rod lock or check valve for a held position. Back covers come as CA pivot or U flat-end too, and FA flange plus LB foot mountings fit the body.
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 MAC20X160SCM FAQ
Push 157.0 N and pull 131.9 N at 0.5 MPa; push 219.8 N and pull 184.7 N at 0.7 MPa; theoretical maximum 32 kgf at 1.0 MPa for the 20 mm bore. Supply air between 0.15-1.0 MPa (22-145 psi) - proof rated 1.5 MPa (215 psi) - and travel the 160 mm stroke at 30-800 mm/s.
No - every MAC ships with the piston magnet built in, so a CMSG, DMSG or EMSG switch clamps straight onto the stainless barrel and reads anywhere in the 160 mm stroke without a special-order piston.
