About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X350-20S
Trim up to 20 mm off the extend stroke with an external stop screw - that is the working flexibility the -20 window gives this MAJ32X350-20S. The 32 mm bore is a double-acting workhorse: 402 N of push and 346 N of pull at 0.5 MPa, 563 N at 0.7 MPa, and 82 kgf theoretical peak; with a 2:1 margin, that push equates to lifting roughly 20 kg vertically. Because the 350 mm length exceeds the 300 mm standard ceiling for 32 mm bores, it is produced as a made-to-order stroke.
Build quality is where this mini earns its keep: a riveted round body packs a stainless-steel barrel around a hard-chrome carbon-steel rod, so washdown spray and humid plant air do not eat it the way they attack painted minis. The magnet is fitted as standard equipment, so CMSG, DMSG and EMSG switches drop on without a special piston order. Note that the stop screw sets position only - it is not a mid-stroke lock, and the rod will drift if air is lost.

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 MAJ32X350-20S Is Used
Tray forming on a carton sealer
Pushes folded trays into a forming station; the 20 mm window lets operators fine-tune reach without changing stroke parts during changeover.
Sample arm in a bottling QC station
Swings a sampling probe into the product stream at intervals; hard-chrome plating on the rod resists the sticky, sugary residue common in beverage plants.
Test rig actuation in an automotive lab
Applies repeatable 402 N-class push loads to dashboard switch assemblies; the bumper pad cushions each stroke end for quieter, longer cycling.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X350-20S the Right Cylinder?
Need more or less muscle? The 25 mm bore offers 245 N at 0.5 MPa for lighter duty, while the 40 mm bore steps up to 628 N. For this 32 mm size, plan continuous work loads around 241 N or less rather than leaning on the full rating. Mounting covers FA flange, LB foot plus I and Y knuckles; on a 350 mm stroke, support the load so bending moments stay off the 12 mm rod, and treat the adjuster as an end stop rather than a brake for suspended weights.
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 MAJ32X350-20S FAQ
Push is 402 N and pull 346 N at 0.5 MPa; at 0.7 MPa expect 563 N push and 484 N pull. The maximum theoretical rating is 82 kgf at 1.0 MPa. The cylinder is double acting, runs on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s, and its extend stroke can be trimmed anywhere inside the ordered 20 mm window.
An external stop screw mechanically limits rod extension, shortening the extend stroke on site by up to 20 mm. It cannot extend travel past the ordered 350 mm, and because it is a hard stop - not a pneumatic cushion or a lock - the rod will settle if supply pressure drops.
