About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X150-30S
Where a washdown line meets a heavy load, the MACJ63X150-30S fits the bill: 63 mm bore, 150 mm stroke, double-acting with a 30 mm on-site trim of the extend stroke and a variable cushion at each end. Push force at 0.5 MPa is 1557.9 N against 1457.4 N on the pull side, and 0.7 MPa lifts the push figure to 2181.0 N. Connections are 1/4"; the rod measures 16 mm.
The rolling-packed stainless body - barrel, aluminium covers and stainless block - keeps grease sealed in and rinse water out, a genuine advantage over painted steel minis in dairy, meat and outdoor service. Sizing shortcut: count on about 935 N of usable push at 0.5 MPa, the 60% figure most designers plan around, instead of the full 1557.9 N. Cycle anywhere from 30 to 800 mm/s on 0.15-1.0 MPa (22-145 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MACJ63X150-30S Is Used
Tray denester pusher
Feeds stacks of trays off a denesting magazine on a ready-meal line; the 30 mm trim sets feed depth per tray size and the stainless barrel stands up to daily caustic washdown.
CIP gate operator
Opens and closes a diverter gate on a clean-in-place skid; the 63 mm bore's 1457.4 N pull at 0.5 MPa retracts the gate against line pressure, and the cushion settles it home.
Dairy crate stacker
Lifts and squares crates into a stacker magazine; with a 2:1 margin the bore raises roughly 79 kg vertically at 0.5 MPa, enough for a full crate load with margin.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X150-30S the Right Cylinder?
A 50 mm MA cylinder pushes 981.3 N at 0.5 MPa - if your load math works with that, it is the leaner choice; 63 mm is as big as the series goes, so this is the ceiling. The 30 mm window trims extend travel only via the stop screw; it is not a brake, and with air off the rod will still move, so add a separate holding valve where a raised load must stay put. Choose the FA flange for face mounting or the LB foot for base mounting; the built-in magnet works with CMSG / DMSG / EMSG switches out of the crate.
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 MACJ63X150-30S FAQ
Push 1557.9 N and pull 1457.4 N at 0.5 MPa; push 2181.0 N and pull 2040.3 N at 0.7 MPa; 317.7 kgf theoretical maximum at 1.0 MPa. Ports are 1/4", speed 30-800 mm/s, pressure 0.15-1.0 MPa (22-145 psi), cushion variable at both ends.
The -30 suffix is a 30 mm window: an external stop screw limits how far the rod extends, so you can shorten the 150 mm stroke anywhere in that range without changing cylinders. It sets position only - it does not lengthen the stroke or hold a load against air loss - and the variable air cushion at each end still softens every stop.
