Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 25mm 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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-20S
Twenty millimetres of on-machine adjustment covers a 25 mm stroke in this double-acting MACJ16X25-20S, with variable cushions at both ends to soften each landing. Force output sits in the light class: 100.5 N extending and 86.4 N retracting at 0.5 MPa, or a theoretical 20.5 kgf at 1.0 MPa - roughly a 10 kg vertical equivalent, or 5 kg with a 2:1 margin.
The body is a stainless tube rolled onto aluminium covers with a hard-chrome plated 6 mm rod, so rinse-down areas and humid plants suit it well. A magnet is fitted as standard for CMSG / DMSG / EMSG switching, and the M5x0.8 ports keep the plumbing compact on crowded machines.

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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-20S Is Used
Cable-latch actuator in a test rack
Flicks a spring latch to release test cables; 20 mm of trim absorbs fixture tolerance between different racks.
Cap-present pusher on a filler
Advances a cap into the check station; a DMSG switch on the standard magnet confirms contact before the torque check runs.
Index pawl on a rotary dial table
Engages the indexing pawl on a small dial plate; cushions prevent chatter as the pawl drops into each detent.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-20S the Right Cylinder?
If 100.5 N at 0.5 MPa feels marginal, step to bore 20 (157.0 N) or bore 25 (245.3 N) in the same MA series. FA flange and LB foot mounting, plus I / Y rod knuckles, cover most fixtures; the 20 mm screw adjusts only the extend stroke and behaves as a stop rather than a brake, so plan external holding for suspended loads. Speed range is 30-800 mm/s across 0.15-1.0 MPa (22-145 psi).
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 MACJ16X25-20S FAQ
At 0.5 MPa: 100.5 N push, 86.4 N pull. At 0.7 MPa: 140.7 N push, 120.9 N pull. Maximum theoretical 20.5 kgf at 1.0 MPa. The stroke is 25 mm, adjustable by 20 mm on extension, with cushioning at both ends, 30-800 mm/s speed and 0.15-1.0 MPa (22-145 psi) operating pressure.
A stainless barrel, hard-chrome plated carbon-steel rod and riveted aluminium covers give this mini genuine corrosion resistance compared with painted bodies - well matched to damp workshops and light washdown zones. There is no tie-rod torque to maintain, just the two cushion screws for end-of-stroke tuning.
