Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X500-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X500-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 500mm 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 MACJ50X500-10S
Five hundred millimetres of travel from a 50 mm bore makes this cylinder a natural for slide pushers and long transfer strokes, with 981 N of push at 0.5 MPa and 1374 N at 0.7 MPa. The extend stroke is adjustable within a 10 mm window at the stop screw, and the variable air cushion at both ends lets you run 30-800 mm/s without hammering the covers. Because the barrel is stainless and the aluminium covers are riveted onto the tube, the body holds up in damp or rinsed-down plant areas where painted minis blister.
Its lift capacity is easy to sanity-check: about 100 kg vertical at 0.5 MPa in theory, so keep real lifts near 50 kg for a comfortable margin, or plan on roughly 589 N of usable force if you prefer the working-load view. Every MACJ ships with the position magnet already installed - DMSG, EMSG or CMSG switches mount without any special piston order.

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 MACJ50X500-10S Is Used
Reject pusher on a 600 mm wide conveyor
The 500 mm stroke reaches across the belt to clear rejects; 981 N at 0.5 MPa moves loaded cartons, and cushions keep the long rod from slamming home.
Dock-door hold-open arm at a distribution hub
The corrosion-resistant stainless body survives outdoor dock washdown; the standard magnet trips an EMSG switch to confirm full-open at the end of travel.
Drop-height gate on a tote discharge chute
Trim the extend stroke in a 10 mm band so diverted totes land at the same level every time; 880 N of pull at 0.5 MPa retracts the gate under load.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X500-10S the Right Cylinder?
Long strokes deserve a load check: at 500 mm, even small side loads will bend the 16 mm rod, so guide the load externally or pick an I or Y rod knuckle instead of cantilevering off the rod. Downsizing to bore 40 saves space but caps you at 628 N push at 0.5 MPa; upsizing to bore 63 buys 1558 N. The stop screw trims the extend stroke only within its 10 mm band and acts purely as a mechanical stop - it will not hold position if supply air fails. FA flange and LB foot mounts cover most frame styles.
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 MACJ50X500-10S FAQ
Push is 981.3 N at 0.5 MPa and 1373.8 N at 0.7 MPa; pull is 880.8 N at 0.5 MPa and 1233.1 N at 0.7 MPa, with a 200.1 kgf theoretical maximum at 1.0 MPa. Bore 50 mm, rod 16 mm, 1/4" ports, adjustable window 10 mm, double variable cushion, supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, and 500 mm is the largest standard stroke for this bore.
No - the magnet is built into the piston as standard on every MA-series cylinder, this one included. CMSG, DMSG and EMSG switches clamp directly onto the stainless barrel at either end of travel, so end-of-stroke confirmation needs no special piston or factory option.
