About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X400-30S
Adjustability is the point of the MAJ16X400-30S: the external stop screw shortens the extend stroke by up to 30 mm from the full 400 mm, set with a spanner right on the machine. Thrust at this 16 mm bore is 100.5 N extending and 86.4 N retracting at 0.5 MPa (140.7 N at 0.7 MPa). Since 400 mm sits beyond the 300 mm catalogue limit for bore 16, this is a made-to-order stroke.
Fixed anti-impact bumper pads cushion both ends of travel - they decelerate the piston but are not an adjustable air cushion, which is the MAC family's job. Mounting covers FA flange and LB foot, with I or Y rod knuckles for linkage work. Budget roughly 60 N of real work from the 100.5 N push rating, and thanks to the standard built-in magnet a CMSG switch can be clamped anywhere along the stainless barrel.

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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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 MAJ16X400-30S Is Used
Carton flap tucker
Tucking the final flap on 400 mm-deep pharmaceutical cartons; 86.4 N of pull retracts the tucker blade clear, and the 30 mm window absorbs carton tolerance.
Pick-station tote ejector
Kicking totes sideways off a warehouse pick shelf; the external stop screw lets staff re-set the eject distance as tote sizes change on the line.
Nest-loading verify probe
Extending a feeler into a parts nest to confirm loading on an assembly cell, with a DMSG switch signalling full extend each cycle.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X400-30S the Right Cylinder?
Size upward if your load exceeds about 60 N working force: bore 20 delivers 157 N and bore 32 402.2 N at 0.5 MPa, both offered with adjustable extend windows. Remember the stop screw sets position only - on air loss the piston drifts, so add an external hard stop where holding matters. Use FA flange or LB foot mounts and I or Y knuckles on the 6 mm rod, and keep the long 400 mm travel free of side loading.
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 MAJ16X400-30S FAQ
Extension develops 100.5 N and retraction 86.4 N at 0.5 MPa; at 0.7 MPa expect 140.7 N and 120.9 N, peaking at 20.5 kgf theoretical at 1.0 MPa. Run clean, dry air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s.
No - the MAJ carries fixed anti-impact bumper pads that only soften stroke-end impact. For adjustable air cushioning, AirTAC's MACJ family is the right pick. Also note the stop screw sets extend position; it does not lock the load if air pressure is lost.
