Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X250-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X250-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 250mm 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 MACJ50X250-10S
Long travel and mid-range muscle meet in the MACJ50X250-10S: a 50 mm bore pushing 981.3 N and pulling 880.8 N at 0.5 MPa over a 250 mm stroke. The -10 code trims the extend stroke by up to 10 mm on site, while variable cushions at each end tame the stop at cycle speeds up to 800 mm/s. Supply pressure spans 0.15-1.0 MPa (22-145 psi).
Construction is a riveted stainless round barrel with aluminium-alloy end covers and a hard-chrome 16 mm rod - no tie rods to retighten and no paint to flake in humid plants. The heterogeneous piston seal doubles as a grease reservoir. Since the magnet ships as standard, position sensing with CMSG, DMSG or EMSG switches needs no special order. For sizing math, count on close to 589 N of dependable work at 0.5 MPa, equivalent to easing about 50 kg through a vertical move at a 2:1 margin.

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 MACJ50X250-10S Is Used
Tote elevator on a pick module
Lifts about 50 kg totes between two shelf levels over 250 mm of travel, cushioned softly at both top and bottom stops.
Cross-belt tray pusher
Sweeps trays off a wide conveyor at a sorting junction, with the 10 mm trim fine-tuning the push length to the chute edge.
Slide feed on a small CNC loader
Feeds aluminium blanks 250 mm into the vise with about 589 N of seating force, confirmed by an EMSG switch at full extend.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X250-10S the Right Cylinder?
If 250 mm of travel plus roughly 1 kN sounds oversized, a 40 mm bore delivers 628.3 N at 0.5 MPa; if you need headroom, the 63 mm bore manages 1557.9 N. On this longer stroke, guide the load with linear rails so side forces do not bend the rod, and pick FA flange or LB foot to match the machine frame. The 10 mm adjuster is a mechanical stop for the extend direction only; the rod still moves if pressure drops, so add external locking for critical holds.
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 MACJ50X250-10S FAQ
Push 981.3 N and pull 880.8 N at 0.5 MPa; push 1373.8 N and pull 1233.1 N at 0.7 MPa; theoretical maximum 200.1 kgf at 1.0 MPa. It is double-acting with an adjustable stroke, runs on 0.15-1.0 MPa (22-145 psi) air and reaches 30-800 mm/s. The port on a 50 mm bore is 1/4".
It is not. The stop screw sets a shorter extend stroke within a 10 mm window and acts as a hard mechanical end stop. Should air pressure fail, the piston can still be pushed along, so a separate locking valve is required wherever load holding is critical.
