Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-100S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-100S is a genuine double acting, adjustable stroke + 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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-100S
A 100 mm window turns the MACJ20X160-100S into a one-cylinder answer for changing products: the extend stroke can be trimmed anywhere from 60 to 160 mm on the machine. At bore 20 mm this double-acting unit delivers 157 N forward at 0.5 MPa and 220 N at 0.7 MPa, with a variable cushion at each end to soften both stops.
Its round stainless-steel barrel resists condensation and light washdown far better than painted mini bodies, while the hard-chrome rod keeps the two-way seal wearing evenly. The magnet is fitted at the factory, so CMSG, DMSG or EMSG switches mount without ordering options. For sizing, treat about 94 N as the practical working force at 0.5 MPa, or roughly an 8 kg vertical lift with 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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-100S Is Used
Cosmetic jar lid press
Presses snap lids onto small cosmetic jars; shorter settings handle pots of different heights without a cylinder change.
Reject chute actuator
Kicks rejected mouldings off a sorting rail, with the 160 mm reach clearing the rail in one move.
Proofer door opener
Rolls light bakery proofer doors open each cycle; the cushion keeps the stainless body quiet even at 800 mm/s.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-100S the Right Cylinder?
Compare both neighbours before ordering: the 16 mm bore offers 100.5 N at 0.5 MPa and the 25 mm bore reaches 245.3 N, so pick smaller for parts-eject duty or larger for heavier presses. Remember the stop screw shortens only the extend stroke and holds nothing when air drops - add an external support if the load must stay put. Mount via FA flange or LB foot, add I or Y knuckles on the rod, and choose PT, G or NPT threads.
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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-100S FAQ
Expect 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push at 0.7 MPa, and 32 kgf theoretical maximum at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, proof pressure 1.5 MPa (215 psi), and the extend stroke trims across a 100 mm window on the 160 mm base stroke.
The stainless barrel and hard-chrome plated carbon-steel rod handle humid, rinsed or outdoor conditions far better than painted minis. Aluminium-alloy covers are riveted onto the tube, and 1/8 inch ports suit compact valve manifolds.
