About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X75-10S
A 20 mm bore double-acting cylinder with a 75 mm stroke that an external stop screw shortens by up to 10 mm after installation - handy when the exact stop position is only known once the machine is assembled. Supply runs 0.15-1.0 MPa (22-145 psi) and rod speed 30-800 mm/s. At 0.5 MPa the piston pushes 157 N and pulls 131.9 N; at 0.7 MPa push climbs to 219.8 N. Keep real continuous work near 94 N so seals and bushings live longer.
The barrel is stainless steel rolled onto aluminium covers, with a hard-chrome plated rod that shrugs off damp or washed-down corners where a painted mini would rust. A fixed anti-impact pad decelerates the rod at each stroke end - it is a bumper, not an adjustable air cushion like the MACJ. Every unit ships with a built-in magnet, so CMSG, DMSG or EMSG switches clip straight on. Plan on roughly 8 kg of vertical lift with 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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MAJ20X75-10S Is Used
Bottle reject gate on a filler line
A short 10 mm kick clears a misaligned bottle at 157 N without disturbing its neighbours on the conveyor.
Carton flap tucker
Trims to a shorter fold position once the carton size is finalised; the stainless barrel tolerates daily wipe-downs.
Index stop on a rotary table
The built-in magnet and a CMSG switch confirm full extension before the table is allowed to index.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X75-10S the Right Cylinder?
If 157 N at 0.5 MPa oversizes your job, the 16 mm bore gives 100.5 N push; for more headroom step up to the 25 mm bore with 245.3 N. The stop screw is a mechanical end stop in the extend direction only - if air pressure drops the rod can still be pushed back, so add a check or locking valve where a load must stay put. FA flange, LB foot and I or Y knuckle mounts all suit this bore; port is 1/8" with an M8x1.25 male rod thread, and the magnet is factory-fitted for switch mounting.
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 MAJ20X75-10S FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa push is 219.8 N. Theoretical peak at 1.0 MPa is about 32 kgf. Stroke is 75 mm with a 10 mm adjustable trim, rod speed 30-800 mm/s, supply 0.15-1.0 MPa (22-145 psi).
FA flange, LB foot plus I and Y rod knuckles bolt straight on, and the magnet is fitted as standard so CMSG / DMSG / EMSG switches need no special piston. Port size is 1/8" on all 20 mm bores and the rod thread is M8x1.25.
