Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X150-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X150-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 150mm stroke, 1/4" 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 MACJ50X150-50S
A 100 kg-class push in a compact round body: at 0.5 MPa the MACJ50X150-50S pushes 981 N, and its 50 mm adjuster window trims the 150 mm extend stroke down to whatever the machine needs. Both ends carry a variable air cushion, letting heavier loads brake smoothly across the full 30-800 mm/s speed band.
Construction is a riveted stainless-steel round barrel with a hard-chrome plated 16 mm rod - a combination that handles washdown, splash and outdoor exposure where painted minis corrode. Sizing rule of thumb: count on roughly 589 N of working force at 0.5 MPa, or treat the cylinder as lifting about 50 kg vertically with a 2:1 margin. Magnets are built in as standard for CMSG / DMSG / 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MACJ50X150-50S Is Used
Sortation divert pusher
Kicks parcels across a sorter lane; about 100 kg of push at 0.5 MPa moves heavy cartons at full belt speed.
Machine tool chip guard
Slides a guard over a lathe or mill spindle; the cushioned ends protect the guard on every 150 mm cycle.
Keg line stopper
Halts kegs at a brewery filling head; the chrome-plated rod and stainless barrel shrug off beer spill and washdown.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X150-50S the Right Cylinder?
One bore down, the 40 mm unit offers 628 N at 0.5 MPa; one bore up, the 63 mm offers 1558 N - pick by real load, not nominal size. Since the 50 mm window is set by a mechanical extend-side stop rather than a lock, never rely on it to park a suspended load. FA and LB mountings fit standard plates, and the built-in magnet pairs with CMSG / DMSG / EMSG switches out of the box.
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 MACJ50X150-50S FAQ
Push 981.3 N, pull 880.8 N at 0.5 MPa; push 1373.8 N, pull 1233.1 N at 0.7 MPa; theoretical maximum 200.1 kgf at 1.0 MPa. The 150 mm extend stroke adjusts across a 50 mm window, cushioning is variable at both ends, speed is 30-800 mm/s and pressure 0.15-1.0 MPa (22-145 psi).
No. The stop screw is a mechanical end stop that shortens the extend stroke; it is not a mid-stroke lock or brake, so the piston can still drift if air pressure is lost. Use a separate locking valve or external stop for load holding.
