About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X50-20S
The MAJ32X50-20S pairs a 32 mm bore with a 50 mm extend stroke that its external stop screw trims by up to 20 mm on site, with no disassembly and no cylinder swap. Double acting, it runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s, delivering 402.2 N of push and 345.6 N of pull at 0.5 MPa.
The rolled stainless barrel with a hard-chrome plated 12 mm rod shrugs off washdown spray and humid shop air, an edge painted minis cannot match. Fixed bumper pads soften end-of-stroke shock (deceleration only - adjustable cushioning is the MAC family's job). In practice, plan for about 241 N of real work at 0.5 MPa; with a 2:1 margin that equals lifting roughly 20 kg vertically.

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 MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X50-20S Is Used
Bottling line kicker arm
The 20 mm trim window lets a filler-line kicker match changing bottle heights without swapping cylinders, backed by 402 N of push at 0.5 MPa.
Reject gate on a checkweigher
Short bursts at 30-800 mm/s flick off-spec packs off the belt, and the stainless barrel survives daily washdown.
Drill fixture clamp
About 241 N of working force at 0.5 MPa holds small aluminum plates against a drill jig, with the stop screw fixing exact clamp position.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X50-20S the Right Cylinder?
Compare both directions before ordering: a 25 mm MAJ reaches only 245.3 N at 0.5 MPa, so it is marginal once friction eats the margin, while a 40 mm bore pushes 628.3 N if you want reserves. The stop screw sets an extend-position end stop, not a lock - on air loss the piston still drifts, so clamp separately where holding matters. FA flange and LB foot mounts plus I and Y rod knuckles cover most fixtures, and the built-in magnet takes CMSG, DMSG or EMSG switches straight from stock.
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 Bumper models: keep speed within the rated range.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X50-20S FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N. At 0.7 MPa those rise to 563.0 N push and 483.8 N pull, and the theoretical maximum is 82 kgf at 1.0 MPa. Ports are 1/8" and the 12 mm rod carries an M10x1.25 male thread.
An external stop screw shortens the extend stroke anywhere within the ordered 20 mm window. It is a mechanical end stop, not a mid-stroke brake, so the rod can still drift if air pressure is lost.
