About the Airtac B01-MAJ Special Purpose Cylinder B01-MAJ32X50-40S
Wide trim range, mid-size muscle: the MAJ32X50-40S lets you shorten its 50 mm extend stroke anywhere inside a 40 mm window with one stop screw. Double acting throughout, it develops 402.2 N forward and 345.6 N back at 0.5 MPa, climbing to 563.0 N and 483.8 N at 0.7 MPa on a 0.15-1.0 MPa (22-145 psi) supply at 30-800 mm/s.
Construction is AirTAC's riveted MA layout - stainless tube, aluminium covers, hard-chromed 12 mm rod - which stands up to mild corrosion in damp cells where painted bodies blister. Bumper pads are fixed for stroke-end deceleration only. As a working number, treat roughly 241 N at 0.5 MPa as the push you can actually use; that is about 20 kg of vertical part weight per cycle once a 2:1 lift margin is applied.

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 (Ø0mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 0 N | 0 N |
| 0.7 MPa | 0 N | 0 N |
| Max (@1.0 MPa) | 0 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac B01-MAJ Special Purpose Cylinder B01-MAJ32X50-40S Is Used
Tray lidding press
The 40 mm window lets one machine run shallow snack trays and deep meal trays; 402 N at 0.5 MPa seats lids without crushing.
Divert paddle on a bakery tray line
Short 30-800 mm/s strokes flip the paddle, and the stainless shell wipes down clean after flour-dusted shifts.
Leak-test probe actuator
The stop screw sets probe contact depth on a test rig; re-trim in seconds between part families.
Is the Airtac B01-MAJ Special Purpose Cylinder B01-MAJ32X50-40S the Right Cylinder?
Size against the 25 mm (245.3 N at 0.5 MPa) and 40 mm (628.3 N at 0.5 MPa) MAJ variants; pick this 32 mm when your load lands between roughly 150 and 240 N after friction allowances. The adjustment is purely a mechanical extend stop, so it cannot serve as a position lock while air is off. Mount by FA flange or LB foot, add I or Y rod knuckles as the linkage needs, and rely on the standard magnet for CMSG, DMSG and EMSG position sensing.
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 B01-MAJ Special Purpose Cylinder B01-MAJ32X50-40S FAQ
Bore 32 mm, stroke 50 mm trimmed inside a 40 mm window: 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, 82 kgf theoretical peak at 1.0 MPa, 1/8" ports, M10x1.25 rod thread, 12 mm rod.
Fixed anti-impact pads decelerate the piston at both ends to cut noise and shock. They are not adjustable air cushions - for that you would choose the MACJ series - and they never restrict the 30-800 mm/s speed band.
