About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X150-40S
Heavy jigs and gates need setting room, and the MACJ63X150-40S provides it: a 40 mm trim window on a 150 mm stroke, 63 mm of bore and dual variable cushions. Running double-acting, it pushes 1557.9 N and pulls 1457.4 N at 0.5 MPa; at 0.7 MPa push reaches 2181.0 N. The 16 mm rod is hard-chrome plated and air feeds through 1/4" ports.
Round stainless barrel, rolled-on aluminium covers, grease-retaining piston seal - the MA build is aimed at plants where painted minis corrode fast. Match parts to the cylinder by weight: it lifts about 79 kg vertically at 0.5 MPa with a 2:1 safety factor, or 158 kg at the raw rating. Full speed envelope is 30-800 mm/s on 0.15-1.0 MPa (22-145 psi); proof pressure 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 (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 MACJ63X150-40S Is Used
Stamping scrap slide gate
Rakes offcuts into a scrap chute under a press; the 40 mm window lets setters re-position the gate for each die, and 935 N of working force at 0.5 MPa clears even packed chutes.
Assembly line transfer pusher
Pushes heavy housings sideways between roller conveyors; the cushion lands each housing against the stop without a bang and the trim absorbs line-to-line spacing drift.
Sluice gate on a treatment channel
Drops a small sluice gate on a wastewater channel; the pull side's 1457.4 N at 0.5 MPa seats the gate while the standard magnet signals open and closed via a DMSG switch.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X150-40S the Right Cylinder?
For lighter duty the 50 mm bore delivers 981.3 N at 0.5 MPa; nothing in the MA series exceeds 63 mm, so this model is the force ceiling of the range. Treat the 40 mm adjuster as an extend-stroke end stop - on air loss the piston drifts, so it cannot serve as a load-holding brake on a hanging mass. Mount FA flange or LB foot, fit I or Y knuckles for swinging loads, and with 150 mm of stroke use external guidance to keep bending loads off the rod. Sensing needs no option code: the magnet is standard, so CMSG / DMSG / EMSG switches attach directly.
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 MACJ63X150-40S FAQ
At 0.5 MPa: 1557.9 N push, 1457.4 N pull. At 0.7 MPa: 2181.0 N push, 2040.3 N pull. Maximum theoretical output is 317.7 kgf at 1.0 MPa. Speed range 30-800 mm/s, supply 0.15-1.0 MPa (22-145 psi), ports 1/4", rod 16 mm.
The FA flange bolts the cylinder face-on to a machine plate, while the LB foot mounts it base-down on a frame; I and Y rod knuckles handle loads that pivot. All are ordering-code options, and the built-in magnet is standard on every unit regardless of mounting.
