Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X40-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X40-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 40mm 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 MACJ16X40-10S
Where a fixture only needs a short, finely set push, the MACJ16X40-10S delivers a 40 mm stroke with a 10 mm on-site trim and the same stainless round-body construction as the rest of the MA line. Double-acting with variable cushions at each end, it makes 100.5 N at 0.5 MPa on extend and 86.4 N on retract, running 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
The hard-chrome 6 mm rod and stainless tube handle splash zones that quickly rust painted housings, a real edge at food benches and wash stations. Size the job around 60 N of usable push at 0.5 MPa rather than the full 100.5 N. Switch feedback needs no extras: the magnet is fitted as standard for CMSG, DMSG and EMSG switches.

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 MACJ16X40-10S Is Used
Rotary table stopper
A part-present stopper on an indexing bench - the 10 mm trim fine-tunes the exact stop position.
PCB test fixture clamp
Clamps boards with about 60 N of usable force at 0.5 MPa, enough for light hold-down without crushing.
Micro-dose needle retract
Pulls a dispensing needle clear over 40 mm in a coating cell; 86.4 N of retract force at 0.5 MPa is ample.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X40-10S the Right Cylinder?
Match the force to the job: 100.5 N at 0.5 MPa suits light clamping; for more, the 20 mm bore delivers 157.0 N or the 25 mm bore 245.3 N at the same pressure. Because the 10 mm window only shortens extend travel, order the cylinder stroke equal to the longest position you need. The stop screw is a position stop, not a brake - expect drift if air pressure drops. An FA flange or LB foot plus I or Y knuckles suits bench fixtures, and the built-in magnet works with CMSG, DMSG and EMSG switches out of the box. Fixed-stroke MAC cylinders are the simpler choice when no trimming is required.
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 MACJ16X40-10S FAQ
Count on 100.5 N push and 86.4 N pull at 0.5 MPa, or 140.7 N and 120.9 N at 0.7 MPa, with a 20.5 kgf theoretical maximum at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi) and keep speed between 30 and 800 mm/s.
The magnet comes built in as standard on every MA-series cylinder, so CMSG, DMSG and EMSG switches can be added at any time. No special-order piston or retrofit is needed.
