Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X500-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X500-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 500mm 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 MACJ50X500-30S
Thirty millimetres of on-site trim across a 500 mm stroke gives commissioning engineers real latitude: set the extend stop once, re-set it when the fixture changes, and the variable air cushion at both ends takes care of deceleration at speeds from 30-800 mm/s. This 50 mm bore MACJ pushes 981 N at 0.5 MPa and 1374 N at 0.7 MPa from a riveted stainless round body that tolerates washdown, dust and outdoor air.
Vertical-lift rule of thumb: about 100 kg at 0.5 MPa on paper, so spec real lifts around 50 kg to keep a 2:1 margin, or design against 589 N if you think in working force. Because the magnet comes standard in the piston, adding a CMSG or EMSG switch is a clamp-on job, not a custom order. Proof pressure is 1.5 MPa (215 psi).

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 MACJ50X500-30S Is Used
Pallet magazine pusher in a cold-store aisle
Cold, damp air kills coated cylinders; the stainless body keeps running while 981 N at 0.5 MPa advances pallet stacks across the full 500 mm.
Leveling ram under a printing press feed table
The 30 mm trim window sets exact table height per stock weight; cushions settle the table without bounce at the top of travel.
Specimen shuttle in a humidity test chamber
Condensation is constant inside the chamber, so the stainless barrel and chrome rod matter; the standard magnet drives a DMSG switch to confirm each shuttle position.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X500-30S the Right Cylinder?
Situated between bore 40 (628 N push at 0.5 MPa) and bore 63 (1558 N), the 50 mm bore handles gate, pusher and ejector loads near 600 N with margin. The 30 mm adjuster is a mechanical end stop for the extend direction only - treat it as a stroke setter, never a brake, since the piston can still move if air is lost. Guide long 500 mm strokes externally to protect the 16 mm rod from bending; I and Y knuckles help with linkages. FA flange and LB foot are the catalogue mounts, with PT thread default and G or NPT options.
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 MACJ50X500-30S FAQ
Force at 0.5 MPa: 981.3 N push, 880.8 N pull. At 0.7 MPa: 1373.8 N push, 1233.1 N pull. Theoretical maximum 200.1 kgf at 1.0 MPa. Bore 50 mm, 16 mm rod, 1/4" ports, M14x1.5 rod thread, 500 mm stroke with a 30 mm adjustable extend window, dual variable cushions, 0.15-1.0 MPa (22-145 psi) supply, 30-800 mm/s speed.
A stop screw at the front cover limits how far the rod extends, trimming the 500 mm stroke by up to 30 mm so you can set exact end-of-stroke position in the field. Combined with the variable air cushion at both ends, you get clean deceleration at whatever position you choose. It is purely a mechanical stop - on air loss the piston can still drift, so add a blocking valve if the load must hold.
