Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-100S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-100S 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 MACJ16X250-100S
Long reach in a slim frame: this 16 mm bore MACJ covers 250 mm of travel and lets maintenance crews wind the extend stroke back by as much as 100 mm with the stop screw instead of swapping the cylinder. Expect 100.5 N forward and 86.4 N return at 0.5 MPa, climbing to 140.7 N at 0.7 MPa. Variable cushions at each end tame the arrival impact of a light carrier travelling anywhere in the 30-800 mm/s band.
The rolling-packed stainless barrel with hard-chrome 6 mm rod stands up to frame condensation far better than coated aluminium minis, so outdoor gates and wet cells stay on the list. Treat about 60 N as the usable push at 0.5 MPa; the same force would lift roughly 10 kg dead vertical, so plan around 5 kg with a 2:1 margin and guide anything heavier. CMSG / DMSG / EMSG switches drop onto the standard magnet for position feedback.

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 MACJ16X250-100S Is Used
Reject pusher arm
A 250 mm sweep nudges misaligned bottles off a bottling conveyor, and the 100 mm trim lets line staff shorten the throw after a guard rail is moved.
Shelf-pick ejector
In a light-duty ASRS pick station the rod ejects one carton from a shelf lane; about 60 N of working force at 0.5 MPa is ample for empty boxes.
Leveling probe drop
Trim the extend stroke back to drop a leveling probe onto pallet stacks of varying height without the rod striking the deck.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-100S the Right Cylinder?
For 250 mm of travel at this force class, alignment matters: keep side load off the 6 mm rod with external rails or an I / Y knuckle, since long thin rods bend easily. If 100.5 N at 0.5 MPa is marginal, the 20 mm bore lifts the same stroke to 157.0 N push; if the trim screw will never be touched, the fixed-stroke MAC gives the same cushioning in a simpler order code. Foot (LB) or flange (FA) mounting, PT / G / NPT thread options, and bear in mind the adjuster is an extend end stop only - it cannot hold a load against air loss.
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 MACJ16X250-100S FAQ
Push is 100.5 N and pull 86.4 N at 0.5 MPa; at 0.7 MPa the cylinder reaches 140.7 N push and 120.9 N pull, with a theoretical maximum of 20.5 kgf at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
Loosen the stop screw, cycle the rod, and lock it at any extend length up to 100 mm short of full stroke - handy when product sizes change on a line. The variable air cushion at both ends is tuned separately from the stop, and the built-in magnet feeds position signals to CMSG / DMSG / EMSG switches.
