About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X160-10S
The largest bore AirTAC's MA family offers, this Dia 40 unit is double-acting with an adjustable extend stroke: an external stop screw trims the 160 mm travel down by up to 10 mm after install, no disassembly needed. It pushes 628 N at 0.5 MPa within a 0.15-1.0 MPa (22-145 psi) supply, which leaves a realistic continuous workload near 377 N once a 40 percent reserve is kept.
A stainless round barrel riveted to aluminum covers, with a hard-chrome plated carbon-steel rod (20 um), shrugs off damp shop air that would pit painted minis. Fixed bumper pads soften the knock at each stroke end - they decelerate only, without the tunable cushioning of the MAC family - and the magnet is fitted as standard for CMSG / DMSG / EMSG switches.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MAJ40X160-10S Is Used
Die-cast trim ejector
Ejects cooled aluminum housings from a trim die; the 10 mm window lets operators reset ejection height without shimming the tool.
Carton lane diverter
Swaps cartons between two conveyor lanes on a case packer, with 160 mm travel and the bumper pad absorbing each lane-change stop.
Weld fixture door clamp
Swings a fixture gate shut to a repeatable seat set by the stop screw, holding weld-gap tolerance consistent across shifts.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X160-10S the Right Cylinder?
Step up from bore 32 (402 N push at 0.5 MPa) when your load would exceed about 240 N; bore 40 has no larger sibling in this series. On a 160 mm stroke the 16 mm rod tolerates little side load - carry lateral force on guide rails or a Y knuckle instead. Mount with an FA flange or LB foot, order the thread you need (PT standard, G or NPT optional; the air port is 1/8"). The stop screw sets a repeatable end position but is purely mechanical: with air lost the rod still drifts, so add an external brake where a load must be held aloft.
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 MAJ40X160-10S FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N; at 0.7 MPa push rises to 880 N and pull to 739 N. Theoretical maximum at 1.0 MPa is 128.1 kgf. Working pressure is 0.15-1.0 MPa (22-145 psi), air should be filtered to 40 um, and speed spans 30-800 mm/s. For continuous duty, size the task to roughly 377 N at 0.5 MPa.
Yes. The piston magnet is a standard fitting, not a paid option, so AirTAC CMSG, DMSG and EMSG switches clip straight onto the stainless barrel for end-of-stroke detection without any special piston order.
