Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X100-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X100-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 100mm 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 MACJ50X100-50S
A 50 mm bore MACJ with a generous 50 mm trimming window: the extend stroke can be shortened by up to 50 mm on site using the external stop screw, while the variable air cushion at both ends soaks up end-of-stroke shock. Double-acting throughout, it develops 981.3 N push and 880.8 N pull at 0.5 MPa, climbing to 1373.8 N at 0.7 MPa with a theoretical ceiling of 200.1 kgf.
The round body is a riveted stainless-steel barrel carrying a hard-chrome plated carbon-steel rod, so it shrugs off mild corrosion and washdown in damp, food or outdoor spots where painted minis rust. Keep real work near 589 N at 0.5 MPa and the cylinder will run cool and last longer. A magnet is built in as standard, so CMSG, DMSG or EMSG switches clip straight on. Working range 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.

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 MACJ50X100-50S Is Used
Pallet strapping press
Drives the strap tensioner shoe home with 981 N at 0.5 MPa; the 50 mm trim window lets one cylinder serve two pallet heights on the same line.
CNC fixture clamping
Holds aluminium housings in a machining fixture, with the built-in magnet and a CMSG switch confirming clamp closure before the cycle starts.
Carton diverter gate
Swings a divert gate on a distribution conveyor at up to 800 mm/s, the air cushion landing the gate quietly at each end of travel.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X100-50S the Right Cylinder?
If 981 N is more than the job needs, the 40 mm bore still gives 628.3 N at 0.5 MPa; when the load grows, step up to 63 mm and 1557.9 N. Note that the stop screw only sets the extend position - it is a mechanical end stop, not a brake, so a suspended load will settle if air is lost. Mount on the FA flange or LB foot, add an I or Y rod knuckle for pivoting links, and check your manifold against the 1/4" port.
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 MACJ50X100-50S FAQ
At 0.5 MPa the 50 mm bore pushes 981.3 N and pulls 880.8 N. At 0.7 MPa push rises to 1373.8 N, and the theoretical maximum at 1.0 MPa is 200.1 kgf. These are double-acting figures with the cushion backed off.
The -50 in the model code is the trim window: the external stop screw shortens the 100 mm extend stroke by up to 50 mm, set with a spanner in minutes. It is a position stop, not a load lock - with no air the rod can still drift. Cushioning and the magnet switching hardware are separate features of the cylinder.
