About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X150-30S
Double-acting with an on-site trimmable stroke, this 16 mm bore MACJ16X150-30S belongs to AirTAC's MA round-body mini family: ordered at 150 mm travel, the external stop screw lets you shorten the extend stroke by up to 30 mm without swapping cylinders. Cushioning is variable at both ends and travel runs 30-800 mm/s. At 0.5 MPa the bore pushes 100.5 N and pulls 86.4 N, rising to 140.7 N at 0.7 MPa, with a 20.5 kgf theoretical ceiling at 1.0 MPa.
The barrel is stainless steel rolled onto aluminium covers in a riveted pack, and the carbon-steel rod carries 20 um of hard-chrome plating - a build that shrugs off washdown and mild corrosion far better than painted minis. A magnet is fitted as standard, so CMSG, DMSG or EMSG switches clamp straight on. For planning, expect about 60 N (0.6 x the 100.5 N rating) of useful push at 0.5 MPa, or roughly 5 kg of 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 (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 MACJ16X150-30S Is Used
PCB fixture ejector
Pushes finished boards off a test nest on a small SMT line; the 30 mm trim window lets the operator fine-set travel to nest depth, and about 60 N of practical push clears a light board.
Blister-pack reject pusher
Taps reject blisters off a pharma packaging conveyor at line speed; the stainless barrel tolerates frequent wipe-downs and the 86.4 N return pull resets the pusher quickly.
Micro slide end stop
Acts as an adjustable stop on a light fixture slide for camera-rail machining, trimming extend travel within 30 mm while two-end cushioning keeps the arrival hammer-free.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X150-30S the Right Cylinder?
Bore 16 is the smallest MA size, so if the load needs more than about 100 N at 0.5 MPa step up: the 20 mm bore gives 157.0 N push and the 25 mm bore 245.3 N at the same pressure. Air supply can be anything from 0.15-1.0 MPa (22-145 psi). Mount with the FA flange or LB foot, and add an I or Y rod knuckle where the push must pivot.
Keep in mind the stop screw sets the extend position but is not a lock - on air loss the rod can still drift back. With a 6 mm rod over a 150 mm stroke, guide the load externally and keep side load low. The magnet is already in, so position sensing via CMSG/DMSG/EMSG costs nothing extra.
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 MACJ16X150-30S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa that rises to 140.7 N push and 120.9 N pull. The theoretical maximum is 20.5 kgf at 1.0 MPa. A practical sizing rule is to count on roughly 60% of the push figure for real work.
An external stop screw shortens the extend stroke anywhere within 30 mm of the ordered 150 mm - it trims, never lengthens. Both ends carry a variable air cushion, and because the magnet is standard, CMSG or DMSG switches signal the trimmed position. Note the stop is not a mid-stroke lock; the rod can drift if air is lost.
