Airtac B01-MACJ Special Cylinder B01-MACJ40X150-50S
The AirTAC Airtac B01-MACJ Special Cylinder B01-MACJ40X150-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø0mm bore and 150mm stroke, PT/G 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 B01-MACJ Special Cylinder B01-MACJ40X150-50S
With the widest trim of this group, MACJ40X150-50S lets you dial the extend stroke down by up to 50 mm on a 150 mm base travel. Push force at 0.5 MPa is 628.3 N against 527.8 N on the pull side, rising to roughly 880 N and 739 N at 0.7 MPa. If you plan lifting duty, count on about 377 N of usable push - 60 percent of rating - before adding any extra safety factor.
Construction is a stainless-steel tube rolled under aluminium-alloy covers with a hard-chrome carbon-steel rod: a sealed round-body package that resists corrosion in damp plants. The adjustable stop is a mechanical end stop only - on air loss the piston can still drift, so it is no substitute for a locking valve. Cushions at both ends and a standard magnet for CMSG / DMSG / EMSG detection complete the package.

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 (Ø0mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 0 N | 0 N |
| 0.7 MPa | 0 N | 0 N |
| Max (@1.0 MPa) | 0 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac B01-MACJ Special Cylinder B01-MACJ40X150-50S Is Used
Pallet-stacker gate interlock
Blocking a pallet gate until loads clear needs dependable 628 N push at 0.5 MPa through a full 150 mm sweep, with cushions damping the slam.
Sample tray indexing in a lab autoclave feeder
The stainless barrel and hard-chrome rod handle humid, washdown-prone surroundings near sterilisation equipment that would corrode painted minis.
Battery-change locator pin on forklift bays
The 50 mm window trims pin engagement depth bay by bay, while both-end cushions give a controlled approach instead of a hard stop.
Is the Airtac B01-MACJ Special Cylinder B01-MACJ40X150-50S the Right Cylinder?
Neighbouring bores frame the choice - the 32 mm MACJ delivers 402.2 N and the 50 mm MACJ 981.3 N at 0.5 MPa, so this 40 mm model covers the mid band. The 50 mm window sets the shortest usable extend stroke, but it is an end stop, never a load-holding brake; a pilot-operated check or blocking valve handles that job. Mount via FA flange or LB foot, add I or Y knuckles for pivoting links, and rely on the standard magnet with CMSG, DMSG or EMSG sensors for stroke-end signals. Run it anywhere in 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, and guide long 150 mm strokes to spare the 16 mm rod.
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 B01-MACJ Special Cylinder B01-MACJ40X150-50S FAQ
MACJ40X150-50S, bore 40 mm, stroke 150 mm, 50 mm trim window. Push 628.3 N / pull 527.8 N at 0.5 MPa; push 879.6 N / pull 738.9 N at 0.7 MPa; maximum theoretical force 128.1 kgf at 1.0 MPa. Rod diameter 16 mm with M12x1.25 male thread and a 1/8" port.
The MACJ adds an external adjuster that shortens the extend stroke within the ordered 50 mm window, while the MAC is fixed-stroke. Both are double-acting with variable air cushioning; if you need a rod on both ends, the MACD variant is the related option in the same family.
