Airtac MAC Stainless Steel Mini Air Cylinder MAC16X400SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC16X400SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø16mm bore and 400mm stroke, M5×0.8 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 MAC16X400SCM
A round-end CM back cover closes this 16 mm bore MAC, a riveted round-body mini cylinder whose stainless barrel and 20 um hard-chrome rod handle humid or lightly washed environments without paint to flake. Double acting with a variable air cushion at each end, it pushes 100.5 N and pulls 86.4 N at 0.5 MPa.
Working force at 0.5 MPa is realistically about 60 N once you stay clear of the limit - enough to index light carriers or trip small mechanisms. The standard-built magnet pairs with CMSG, DMSG and EMSG switches, and M5x0.8 ports plus an M6x1.0 rod thread keep fittings and tooling simple. Pressure range is 0.15-1.0 MPa (22-145 psi); speed 30-800 mm/s.

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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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 MAC16X400SCM Is Used
Slide extension on jeweller workholding
Extends a light vise jaw 400 mm on a benchtop engraving fixture; 60 N of practical force moves small metal pieces without marring them.
Tote locator pin in a compact AS/RS
Pins plastic tote positions on a small storage shuttle; the round-end CM cover takes a clevis pin for the reciprocating motion.
Drop gate on a tablet counter
Releases counted tablets down a chute; the variable cushion quiets the gate so nothing jumps at the bottom of travel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC16X400SCM the Right Cylinder?
Need more than the 20.5 kgf theoretical ceiling of this bore? The 25 mm size reaches 245.3 N push at 0.5 MPa. Because the piston drifts whenever air pressure is removed, hold vertical loads with a rod lock or pilot check valve instead of relying on the cushion - the cushion only absorbs end-of-stroke shock. The CM cover suits clevis pinning on swinging linkages; FA flange and LB foot brackets cover fixed mounts.
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 MAC16X400SCM FAQ
Use 100.5 N push and 86.4 N pull at 0.5 MPa as the baseline, 140.7 N push and 120.9 N pull at 0.7 MPa for higher supply, and 20.5 kgf as the 1.0 MPa theoretical maximum. The 400 mm stroke is standard (limit 500 mm) and motion runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi).
The rolled stainless tube with its hard-chrome plated rod resists condensation, splashes and periodic washdown far better than painted-steel or plain aluminium minis, and there are no tie-rod joints to work loose. It is a self-contained riveted body, so sealing stays reliable even in damp production corners.
