Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X300-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X300-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 300mm 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 MACJ50X300-10S
Long 300 mm travel in a compact round body: this double-acting cylinder carries a 10 mm extend-stroke trim and variable cushions at both ends, so you can run faster across the full travel without hammering the covers. At 0.5 MPa (72 psi) the 50 mm bore generates 981 N push and 881 N pull, rising to 1374 N push at 0.7 MPa (102 psi).
Converted for lifting, 981 N equates to roughly 100 kgf, so with a 2:1 safety margin it raises about 50 kg vertically. The riveted stainless barrel and 20 um hard-chrome plated rod resist corrosion in humid plants and outdoor gates alike, while the grease-retaining piston seal cuts maintenance. Position feedback needs no extras: the magnet is fitted as standard and pairs with CMSG, DMSG or EMSG switches.

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 MACJ50X300-10S Is Used
Cross-transfer between two belt lines
Slides 8 kg totes sideways from infeed to outfeed conveyor; 981 N push at 0.5 MPa (72 psi) moves them briskly with cushioned stops.
Oven door actuation in a biscuit plant
Swings a 240 mm access door every batch; stainless construction handles heat-adjacent humidity and flour dust without corroding.
Indexing lift on an assembly carousel
Raises a pallet fixture of about 45 kg per station with a 2:1 margin; the magnet and DMSG switch confirm top-of-stroke before indexing.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X300-10S the Right Cylinder?
Size check: the 40 mm bore offers 628 N push at 0.5 MPa (72 psi) and the 63 mm bore 1558 N, so the 50 mm sits between them at 981 N. The 10 mm adjuster sets extend length but not position under load, and without pressure the rod still moves, so fit a lock or metering valve for hanging loads. Choose FA flange or LB foot mounting and I or Y knuckles as needed; with 300 mm of travel, keep the load guided so side forces do not bow the 16 mm rod.
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 MACJ50X300-10S FAQ
Push 981 N and pull 881 N at 0.5 MPa (72 psi); push 1374 N and pull 1233 N at 0.7 MPa (102 psi); theoretical maximum 200.1 kgf at 1.0 MPa (145 psi). Double-acting, with a 10 mm adjustable window on the extend stroke and variable cushions at both ends. Proof pressure is 1.5 MPa (215 psi).
Yes, the piston magnet is built in as standard, so CMSG, DMSG or EMSG switches attach to the barrel with no special-order cylinder. The 10 mm stop screw only shortens the extend stroke on site; it will not hold the piston against a load if air is lost, which is why a locking valve is advised for suspended loads.
