About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X100-20S
Trimmable by 20 mm along its 100 mm extend travel, the MAJ32X100-20S uses an external stop screw to set a repeatable forward position on a 32 mm bore rated 402 N push at 0.5 MPa. AirTAC fits the position-sensing magnet as standard equipment, so CMSG / DMSG / EMSG switches clip onto the stainless barrel with no special piston order.
Dedicate about 241 N of the rating to real work at 0.5 MPa and the cylinder holds pace across the 30-800 mm/s speed range without bottoming hard - the fixed bumper pads absorb the residual impact, though they are deceleration pads rather than adjustable air cushions (that capability belongs to the MAC family).

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 MAJ32X100-20S Is Used
Recipe-change gate on a filler
Bottle routing gates on a filling line need a different forward position per bottle format; the 20 mm window covers the formats without moving the cylinder or re-teaching sensors.
Z-stop for a dispensing head
A glue dispensing head is lowered to a set height above PCBs; the stop screw fixes that height within the 20 mm trim and a DMSG switch verifies arrival on every cycle.
Gate latch on a machine guard
Interlocked guard latches cycle thousands of times per shift; 346 N of pull at 0.5 MPa retracts the latch pin briskly while the riveted stainless body shrugs off shop-floor mist.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X100-20S the Right Cylinder?
Benchmarks either side: the 25 mm bore delivers 245 N at 0.5 MPa and the 40 mm bore delivers 628 N; the 32 mm is the middle choice for gates, clamps and lifts around 100 mm of travel. Mounting options are FA flange or LB foot, with I / Y rod knuckles for linkage misalignment; the adjustable series omits SDB. The 20 mm stop is a mechanical end stop - it will not hold a suspended load if supply air fails, so fit a counterbalance where the load hangs. The 12 mm rod takes M10x1.25 male threads for standard accessory attachments.
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 MAJ32X100-20S FAQ
Expect 402 N push and 346 N pull at 0.5 MPa, 563 N and 484 N at 0.7 MPa, and 82 kgf theoretical maximum at 1.0 MPa. Supply pressure runs 0.15-1.0 MPa (22-145 psi), rod speed 30-800 mm/s, and the external stop screw trims the extend stroke within the ordered -20 window.
The barrel is high-precision stainless steel with the aluminium-alloy covers riveted on, and the 12 mm rod carries a 20 um hard-chrome plate. In damp food areas, outdoor machinery or coolant-heavy cells the body will not rust or shed paint, keeping the sliding surface smooth far longer than coated mini cylinders.
