Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X50-20SLB
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X50-20SLB is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 50mm stroke, 1/8" 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 MACJ32X50-20SLB
Mounted on LB feet, the MACJ32X50-20SLB bolts flat to a machine plate while keeping everything the MA recipe is known for: a riveted stainless-steel round barrel, aluminium-alloy covers, a hard-chrome plated 12 mm piston rod and a 20 mm window for trimming the 50 mm extend stroke with the built-in stop screw. A variable cushion at each end absorbs the landing, so faster cycles or heavier pushes do not hammer the caps.
Force-wise, expect 402.2 N push and 345.6 N pull at 0.5 MPa, and 563.0 N push at 0.7 MPa. For day-to-day sizing, treat about 241 N as the practical push budget at 0.5 MPa and the cylinder runs with headroom. The magnet ships inside as standard equipment, so CMSG, DMSG and EMSG switches snap on for end-of-stroke signals. Clean 40 um filtered air, 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi).

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MACJ32X50-20SLB Is Used
Machine-guard interlock pin
An LB-footed cylinder is easy to bolt beside a sliding machine guard; the rod drives an interlock pin and the standard magnet tells the PLC when the pin is home.
Nest clamping on CNC jigs
Clamping small parts into CNC fixture nests takes modest force; 402.2 N at 0.5 MPa holds a machined boss and the 20 mm trim window lets the setter shorten the clamp travel to suit each jig.
AGV dock latch actuation
Automated guided vehicles use short-stroke latches to dock with charging stations; the stainless barrel laughs at the wet, dusty warehouse floor that corrodes painted bodies.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X50-20SLB the Right Cylinder?
The LB foot suits upside-down or side-wall mounting where a flange would shadow the work; FA flange and I or Y rod knuckles are the other options. Between bores, 25 mm gives 245.3 N at 0.5 MPa and 40 mm gives 628.3 N, bracketing this 32 mm bore's 402.2 N. The stop screw sets where the extend stroke finishes - it is not a mid-stroke lock, and a piston drifting under lost air still needs an external clamp. Ports depend on the bore alone, so this one takes 1/8 inch.
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 MACJ32X50-20SLB FAQ
Expect 402.2 N push and 345.6 N pull at 0.5 MPa, 563.0 N push and 483.8 N pull at 0.7 MPa, and a theoretical peak of 82 kgf at 1.0 MPa. The cylinder needs 40 um filtered air at 0.15-1.0 MPa (22-145 psi), tolerates 1.5 MPa (215 psi) proof pressure and cycles from 30-800 mm/s.
As ordered it carries an LB foot for flat plate mounting; the same bore is also available as an FA flange, or with I and Y rod knuckles on the basic version. Ports depend on the bore alone, so every 32 mm MA cylinder uses a 1/8 inch port, and the rod thread is M10x1.25.
