About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X450-30S
For long push strokes in tight envelopes, the MAJ32X450-30S pairs a 450 mm stroke with a 30 mm adjustable window, so maintenance teams can dial the extend stop in after the fixture is bolted down. Expect 402 N forward and 346 N return at 0.5 MPa; at 0.7 MPa the figures reach 563 N and 484 N.
The two-way piston seal stores grease as it runs, cutting lube chores over the long travel. Note the anti-impact pads are fixed bumpers, not adjustable air cushions - if cushioning matters, the MACJ family adds it on top of the adjuster. The standard magnet feeds CMSG / DMSG / EMSG switches for end-position checks.

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 MAJ32X450-30S Is Used
Case divert pusher
Knocks cases across a belt into a takeaway lane; 402 N at 0.5 MPa moves 12 kg cases easily, and the 30 mm trim tunes the contact point during commissioning.
Carton tuck arm
Folds and tucks carton flaps on a packaging line; the fixed bumper softens stroke-end knock through 30-800 mm/s cycling shifts after shift.
Valve rack actuator
Trips hand valves on a water-treatment skid; the stainless round barrel shrugs off outdoor damp that pits painted mini cylinders in the same role.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X450-30S the Right Cylinder?
Bore choice: 25 mm (245 N at 0.5 MPa) suits light returns, 40 mm (628 N) suits heavy tooling; this 32 mm cylinder splits them with 402 N push and 346 N pull, leaving roughly 241 N for real work at 0.5 MPa.
Over 450 mm, keep side loads off the rod with linear guides - the 12 mm chrome rod handles axial force far better than bending. Pick FA flange or LB foot mounting, and remember the stop screw is a positioning trim, not a mid-stroke brake; the rod coasts if pressure falls away.
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 MAJ32X450-30S FAQ
Push at 0.5 MPa is 402 N, pull 346 N; at 0.7 MPa push 563 N and pull 484 N; theoretical maximum at 1.0 MPa is 82 kgf. Pressure spans 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, and speed is 30-800 mm/s.
No. The MAJ32X450-30S carries fixed anti-impact pads that merely soften the stroke-end knock; they do not decelerate adjustable loads like an air cushion. If adjustable cushioning matters, AirTAC's MACJ family combines the stroke adjuster with cushions.
