About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X150-75S
A 75 mm tuning band makes this the flexible member of the bore-20 family: the MAJ20X150-75S reaches 150 mm as ordered, yet its extend stroke can be stopped anywhere inside a 75 mm band from the panel in front of you. Double-acting drive gives 157 N push and 132 N pull at 0.5 MPa, with 220 N available at 0.7 MPa.
The body is a compact riveted round package - stainless barrel, aluminium covers, hard-chrome plated 8 mm rod - so it survives coolant spray and rinse-down that would pit painted minis. Its fixed bumper pads damp stroke-end shock, and the standard-fit magnet accepts CMSG, DMSG and EMSG switches without any piston options. Plan the actual job around about 94 N of push at 0.5 MPa; the rest of the 157 N rating belongs to your 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 MAJ20X150-75S Is Used
Tote-lane gate on sortation
Push totes onto spur lanes in a small warehouse sorter; the 75 mm band adapts one cylinder to lanes of different offsets as the layout changes.
Test-rig actuator stroke trim
Drive light test fixtures where each product revision needs a slightly different press height - turn the stop screw instead of re-plumbing the station.
Glue-bead guide on a woodworking line
Set roller or nozzle depth on edge-gluing stations; 157 N holds the guide against panel spring-back at 0.5 MPa.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X150-75S the Right Cylinder?
Between the 16 mm bore (about 100 N at 0.5 MPa) and the 25 mm bore (245 N), this 20 mm bore at 157 N sits mid-pack - right for gates, stoppers and small lifts that outgrow a micro cylinder. The trim screw shortens extension only and never lengthens it past 150 mm, and because it acts as an end stop rather than a lock, a supply-air loss still lets the rod drift - separate clamping for critical holds. Choose FA or LB mounting, add I or Y knuckles for linkage work, and for the full 150 mm travel avoid rod side loads by guiding in linear slides. CMSG, DMSG or EMSG sensors mount out of the box thanks to the built-in magnet.
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 MAJ20X150-75S FAQ
At 0.5 MPa: 157 N extend and 132 N retract. At 0.7 MPa: 220 N extend and 185 N retract. Theoretical maximum is about 32 kgf at 1.0 MPa. Stroke is 150 mm double-acting with a 75 mm external trim window, a 30-800 mm/s speed range, and 1/8" ports on the covers.
FA flange and LB foot brackets fit the round body, while I and Y rod knuckles handle pivoting links; the adjustable-stroke version takes no SDB or back-cover codes. For position signals, the standard magnet lets CMSG, DMSG or EMSG switches clamp anywhere along the stainless barrel.
