Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X150-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X150-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø40mm 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 MACJ40X150-10S
Long travel, small trim: the MACJ40X150-10S gives a 40 mm bore 150 mm of double-acting stroke with a fine 10 mm extend-side adjustment for hitting a repeatable datum on the machine. Both ends carry a variable air cushion, the barrel is stainless steel, and the rod is hard-chrome plated carbon steel - a round-body package that holds up in washdown and outdoor duty where painted minis corrode. Air: 0.15-1.0 MPa (22-145 psi); speed 30-800 mm/s.
Push at 0.5 MPa (73 psi) is 628 N with 528 N on retract, giving roughly 377 N of dependable working force or a 2:1 vertical lift near 32 kg. At 0.7 MPa those figures climb to 880 N and 739 N. The standard-built magnet works with CMSG / DMSG / EMSG switches out of the box. Treat the adjuster as a stroke end stop only - on air loss the piston is free to move, so never use it to park a load.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MACJ40X150-10S Is Used
Order-bin pusher
Moves a pick bin onto the takeaway conveyor at a goods-to-person station, 150 mm of stroke clearing the lane.
Hopper slide-gate operator
Cracks open a small granulate hopper gate for dosing; the 10 mm trim sets the opening depth for repeatable feed.
Guard door interlock push
Seats a sliding machine guard onto its interlock, cushions damping the close so the frame does not shock-load.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X150-10S the Right Cylinder?
Mid-range duty fits here: 402 N at 0.5 MPa from a 32 mm bore or 981 N from 50 mm, with this 40 mm cylinder supplying 628 N over 150 mm of travel. The narrow 10 mm window is for fine end-of-stroke setup rather than product changeover. On a 150 mm stroke, keep side loads off the 16 mm rod - guide the payload externally. FA flange and LB foot options plus I/Y rod knuckles; the piston magnet (standard) reads on CMSG/DMSG/EMSG switches. Air loss means drift, so add an external stop or brake if holding is required.
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 MACJ40X150-10S FAQ
Expect 628 N at 0.5 MPa on extend and 528 N on retract, 880 N and 739 N at 0.7 MPa, and 128 kgf theoretical at full 1.0 MPa. The 150 mm stroke trims by up to 10 mm; supply runs 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, double-acting with cushioned ends.
Each end has a variable cushion you set by needle, decelerating the piston before it lands so heavier or faster loads do not hammer the covers. Combined with the riveted stainless barrel and hard-chrome rod, the unit stays sealed through washdown cycles.
