Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 250mm 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 MACJ16X250-75S
A 75 mm window makes the MACJ16X250-75S the most flexible bore 16 unit in the run: set the extend stroke anywhere from 175 to 250 mm with the stop screw and a spanner. Double-acting throughout, it pairs the adjustment with a variable cushion at both ends and delivers 100.5 N push / 86.4 N pull at 0.5 MPa.
The stainless round barrel and hard-chrome plated 6 mm rod cope with outdoor splash and washdown, and the built-in magnet is standard, so CMSG / DMSG / EMSG switches drop on for position feedback. Practically, that 100.5 N rating means about 60 N of usable work and a vertical lift of roughly 5 kg - useful when matching fixture weights. Supply 0.15-1.0 MPa (22-145 psi) and run 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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-75S Is Used
Parcel diverter
Swings a lightweight guide across a sorter lane to send small parcels to the reject spur, stroke set per lane width.
Probe dip station
Lowers a slim conductivity probe into wash-test beakers, the 175 mm minimum travel keeping it clear of the rim until triggered.
Bin stop gate
Catches rolling tote boxes at a pick face with a cushioned stop that halts them without tipping the load.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-75S the Right Cylinder?
Where the load outgrows this bore, the 20 mm bore gives 157.0 N and the 25 mm bore 245.3 N at 0.5 MPa without changing mounting style. Because the stop screw is a mechanical end stop rather than a lock, the piston can still be back-driven if air is lost - do not rely on it to park a load. FA flange or LB foot mounting plus I / Y rod knuckles suit most small fixtures; with 250 mm of slim-rod travel, use a guide or low-friction slide to keep bending loads off the rod.
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 MACJ16X250-75S FAQ
At 0.5 MPa: 100.5 N on extend and 86.4 N on retract. At 0.7 MPa: 140.7 N on extend. The theoretical ceiling is 20.5 kgf at 1.0 MPa, with proof pressure of 1.5 MPa (215 psi).
Air trapped at each end decelerates the piston before it reaches the cover, so near the top of the 30-800 mm/s range you can still stop light loads without metal-to-metal hammering; cushion strength is dialed in with the cover screws.
