Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X200-100S
The AirTAC MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X200-100S is a genuine double acting, double rod, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 200mm 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 MACJ50X200-100S
With a 200 mm ordered stroke and a generous 100 mm adjustment window, this MACJ can be tuned on site to any extend travel between roughly 100 and 200 mm - one cylinder covers several station designs. It runs on 40 um filtered air at 0.15-1.0 MPa (22-145 psi).
Construction is AirTAC's rolling-packed MA platform: a stainless round barrel with aluminium covers riveted home, a 16 mm hard-chrome-plated rod, and grease-retaining two-way piston seals. Because the magnet is a standard fitting, CMSG, DMSG or EMSG switches drop on for end-of-stroke signals.

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 | Force (both ways) |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 kgf |
MAJ / MACJ are double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X200-100S Is Used
Pallet elevator station
Raises a 45 kg pallet layer about 150 mm.
Cross-belt pusher arm
Pushes cartons sideways off a 200 mm-wide lane in a logistics sorter. Dual cushions let operators raise belt speed past 500 mm/s while keeping the transfer quiet.
Sample tray indexer
Advances lab sample trays into an analyzer slot. The stainless barrel stands up to daily wipe-down with mild solvents, and the magnet feeds tray-in-position to the controller.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X200-100S the Right Cylinder?
Remember the adjuster is an extend-stroke end stop, never a holding brake; if air fails, the load can coast, so add an external lock for suspended loads. Choose the FA flange or LB foot, bolt on an I or Y knuckle where the load articulates, and guide long-travel moves externally so the rod sees minimal side load.
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 MACJ50X200-100S FAQ
For sizing, treat roughly 589 N as usable working force at 0.5 MPa. The 16 mm rod carries an M14x1.5 male thread, ports are 1/4 in., and pressure runs 0.15-1.0 MPa (22-145 psi).
A stop screw at the front cover shortens the extend stroke by any amount up to the 100 mm window, so the effective extend travel can be set anywhere between about 100 and 200 mm with wrenches, not a new order. It sets position only - it is an end stop, not a load-holding lock - and the variable cushion at each end still protects the covers at full speed.
