Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X75-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X75-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 75mm 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 MACJ50X75-10S
When a standard 75 mm stroke lands slightly long for the fixture, the -10 window lets you shave up to 10 mm off the extend stroke on the machine - no shim stacking, no re-ordering. The 50 mm bore backs it with about 981 N of push and 881 N of pull at 0.5 MPa, and 1374 N of push at 0.7 MPa, cushioned variably at both ends.
Stainless barrel, hard-chrome plated rod and riveted aluminium covers give this round mini a real edge in spray zones and humid plants where painted bodies bloom with rust. The magnet is factory-fitted, so CMSG, DMSG and EMSG switches drop on for position feedback. Keep continuous duties near 589 N at 0.5 MPa and the cylinder will hold its cycle rate without overheating the seals.

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 MACJ50X75-10S Is Used
Carton flap tucker
A folding arm tucks top flaps on cartons moving at line speed; 10 mm of trim aligns the tuck point per carton height and the cushion ends the fold softly.
Small arbor press
Pressing bushings into housings uses about 981 N at 0.5 MPa, and the trimmed extend stroke sets press depth without mechanical spacers.
Reject gate on a checkweigher
When the checkweigher flags an underweight pack, the cylinder flicks the reject gate; the built-in magnet feeds a CMSG signal back to the PLC.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X75-10S the Right Cylinder?
The 75 mm stroke sits well under the 500 mm standard limit for this bore, so it ships as a catalogue item. Compared options: MACJ40 for about 628 N at 0.5 MPa, MACJ63 for about 1558 N. The stop screw fixes the extend position mechanically; it does not lock the rod against drift when air is lost, so use a blocking valve for held loads. FA flange, LB foot, plus I and Y knuckles cover the fixture menu, and the 1/4 inch ports suit standard fittings.
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 MACJ50X75-10S FAQ
Push about 981 N and pull about 881 N at 0.5 MPa; push about 1374 N and pull about 1233 N at 0.7 MPa; about 200 kgf theoretical maximum at 1.0 MPa. The bore is 50 mm, rod 16 mm with M14x1.5 thread, ports 1/4 inch, pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, cushion adjustable at both ends.
The stainless barrel and hard-chrome rod tolerate washdown splash and condensation, which is why the MA series appears in food handling and outdoor cells. Wipe the rod periodically and keep the air filtered to 40 um, and the riveted body sealing stays intact through repeated wet cycles.
