Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X350-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X350-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 350mm 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 MACJ50X350-10S
Reach matters on conveyor cross-transfers, and this 350 mm stroke MACJ puts 981.3 N of push at 0.5 MPa (22-145 psi) at the end of that travel. AirTAC builds the MA family as a round-body cylinder: a stainless-steel tube, a 16 mm hard-chrome rod and rolled aluminium heads - a package that tolerates washdown and outdoor dust far better than painted minis.
The -10 code gives a 10 mm trim on the extend stroke, handy for nudging a stop position after installation without re-piping. Both heads carry the variable air cushion, so the 589 N you can count on for actual work decelerates smoothly even near the 800 mm/s speed ceiling. Ports are 1/4 in., sized to feed this bore fast.

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 MACJ50X350-10S Is Used
Cross-belt transfer pusher
Kicking cartons across a 350 mm gap between conveyor lanes is the classic use; 981.3 N at 0.5 MPa clears a stalled pack, and the cushion keeps the pusher from cracking into its stop.
Drum lid seating press
Seating lids on 60 L drums takes a steady press of around 55 kgf; this cylinder holds that class with margin, and the stainless barrel handles the splash zone near the filling station.
Pallet-strapper clamp
Holding a strap tension head against a pallet face during strapping suits the long stroke; the 10 mm window trims the clamp position after the frame is built.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X350-10S the Right Cylinder?
Bore 40 offers 628.3 N at 0.5 MPa and bore 63 offers 1557.9 N, so a 50 mm bore is right when the load sits between roughly 380 and 590 N of working force. Over 350 mm of travel, keep side-loading low - the 16 mm rod is tough but a long unsupported stroke punishes misalignment, so guide the load externally. Mounts are FA flange or LB foot, plus I and Y knuckles; the internal magnet pairs with CMSG / DMSG / EMSG switches. Note the stop screw sets position only - under air loss a load can still shove the rod, so add a pressure-trap valve for positive holding.
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 MACJ50X350-10S FAQ
Expect 981.3 N push and 880.8 N pull at 0.5 MPa; at 0.7 MPa the numbers are 1373.8 N push and 1233.1 N pull. The 1.0 MPa theoretical maximum is 200.1 kgf. Size the job for about 589 N of true work so friction and sagging pressure never stall the cylinder.
The barrel is stainless steel and the rod is carbon steel hard-chrome plated to about 20 um, while the aluminium heads are roll-crimped onto the tube - no exposed fasteners to corrode. That build suits washdown zones and outdoor gates. Proof pressure is 1.5 MPa (215 psi) and the temperature range is -20 to +70 C.
