Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X150-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X150-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø20mm bore and 150mm stroke, 1/8" 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 MACJ20X150-10S
Think of this as a long-reach cylinder with a fine-tuning collar: the MACJ20X150-10S extends 150 mm and the stop screw narrows that by up to 10 mm, which is usually all the slack a fixture needs once it is aligned. It is double-acting with a variable air cushion at each end, and the 20 mm bore generates 157 N of push at 0.5 MPa - about 8 kg of vertical lift capability with a 2:1 safety factor.
The MA round-body format uses a riveted stainless-steel barrel and a hard-chrome plated carbon-steel rod, a combination that tolerates splash, humidity and outdoor air far better than painted minis. Grease-retaining two-way seals cut maintenance intervals, and since the magnet is built in as standard, CMSG / DMSG / EMSG switches drop on for stopper-up and stopper-down signals.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MACJ20X150-10S Is Used
Pallet-lane stopper at a warehouse conveyor
A vertical stopper blade rises to hold empty pallets at a pick station; the 10 mm trim evens out blade height across lanes, and 8 kg-class lift headroom handles the blade plus bracket.
Spill gate under a powder hopper outlet
A slide gate opens and closes a small hopper outlet; the stainless barrel copes with damp powder-room air while the end cushions stop the gate cracking against its frame.
Panel squaring before edge gluing
A pusher toes panels square against a fence on a cabinet line; the 150 mm reach spans the panel depth and the magnet confirms full-extend before the glue bar fires.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X150-10S the Right Cylinder?
Downsize to bore 16 for 100.5 N at 0.5 MPa if friction is low; upsize to bore 25 (245.3 N) for heavier gate blades or sticky slides. With a 150 mm unsupported stroke, keep side loads off the 8 mm rod by guiding the part itself. The 10 mm adjuster is an extend-direction stop only - it will not lock the load if air fails, so plan a pilot-checked valve or brake where needed. FA and LB mounts cover flange or foot fixing; speed window is 30-800 mm/s.
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 MACJ20X150-10S FAQ
Yes: 157 N push and 131.9 N pull at 0.5 MPa; 219.8 N push and 184.7 N pull at 0.7 MPa; theoretical maximum 32.0 kgf at 1.0 MPa. Pressure range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and the 150 mm stroke sits inside the 300 mm standard-stroke limit for bore 20.
It is the adjustable-stroke window: a stop screw at the head lets you shorten the 150 mm extend stroke by any amount up to 10 mm to absorb fixture tolerance. It does not lengthen the stroke, and it is not a mid-stroke lock or holding brake - the rod can still drift if air is lost. Retraction stays at full stroke, and both ends carry a variable air cushion.
