About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X250-50S
Double-acting and field-trimmable, the MAJ32X250-50S takes an external stop screw that shortens the extend stroke anywhere inside a 50 mm window. At 0.5 MPa the 32 mm bore delivers 402 N forward and 345.6 N back, rising to 563 N forward at 0.7 MPa.
Its riveted stainless barrel and 12 mm hard-chrome rod shrug off splash and humid air that quickly stains painted mini bodies. The magnet comes built in as standard, so CMSG, DMSG or EMSG switches clip on without ordering a special piston. Expect roughly 241 N of usable push at 0.5 MPa once you derate for a 2:1 margin.

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 MAJ32X250-50S Is Used
Bottle reject pusher
A 250 mm stroke with 402 N of push clears a jammed 500 ml bottle from an inline capper rail at a beverage plant, and the 50 mm trim sets the exact parking depth.
PCB tote shuttle
Moves loaded SMT tote boxes between two benches 250 mm apart, where the stainless barrel tolerates the humidity of a flux-wash area.
Labeler head gap set
Trims the extend depth of a labeling head per container size within the 50 mm window, so changeovers need no shimming or reordering.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X250-50S the Right Cylinder?
If 402 N at 0.5 MPa overshoots the job, the 25 mm bore (245 N push) saves air and space; if the load creeps past 400 N, step up to the 40 mm bore at 628 N. Ports are 1/8" on this bore and the rod thread is M10x1.25. Remember the stop screw is an extend-stroke end stop only - on sudden air loss the rod still drifts, so add a separate lock for load holding. FA flange or LB foot mounting, with I and Y rod knuckles available, covers most frame layouts; speed range is 30-800 mm/s.
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 MAJ32X250-50S FAQ
At 0.5 MPa this 32 mm bore pushes 402.2 N and pulls 345.6 N; at 0.7 MPa that rises to 563.0 N push and 483.8 N pull. The theoretical ceiling is 82 kgf at 1.0 MPa. It runs double-acting on 0.15-1.0 MPa (22-145 psi) air at 30-800 mm/s.
An external stop screw shortens the extend stroke by up to 50 mm from the ordered 250 mm; fixed bumper pads soften both stroke ends but the screw is not an adjustable air cushion. Air ports are 1/8" and the rod thread is M10x1.25.
