About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X15-10S
Short travel, tight trim: this MAJ40X15-10S runs a 15 mm stroke that the external stop screw narrows by up to 10 mm, handy when a fixture position only shows itself once the tooling is assembled. Double-acting air gives 628 N of push and 528 N of pull at 0.5 MPa, with 880 N on tap at 0.7 MPa.
Its round stainless barrel and 16 mm hard-chrome rod stand up to coolant mist and washdown where aluminium minis pit, and the riveted body keeps the footprint small. Stroke-end impact is handled by fixed bumper pads, not an adjustable cushion. As a working figure, treat about 377 N as the realistic push at 0.5 MPa, and halve the theoretical 64 kg vertical lift to roughly 32 kg for a two-to-one margin on part weight.

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 MAJ40X15-10S Is Used
Glue nozzle fine setting
Positions a hot-glue nozzle gap on a carton-closing machine; the 10 mm trim lets operators close the nozzle standoff after bead trials without re-shimming.
Gauging probe actuation
Presses a dial or electronic probe onto machined shafts at an inline gauging station, where the 15 mm travel and 628 N push seat the stylus repeatably.
Lug marking punch
Drives a character punch into copper cable lugs on a harness line; the short stroke keeps cycle time low while the bumper pad quiets the hit.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X15-10S the Right Cylinder?
This 40 mm bore is the ceiling of the MA line at 628 N push (0.5 MPa); if 402 N from a MAJ32X15-10 covers the load, the smaller bore saves compressed air. FA flange and LB foot mounts both suit a 15 mm stroke, and I or Y knuckles thread onto the M12x1.25 rod; the standard magnet takes CMSG, DMSG or EMSG switches without ordering a sensing variant. The 10 mm adjuster is purely an extend-side end stop - it will not hold a load against gravity if supply air drops. Short strokes like this see high cycle counts, so keep the load centred on the rod.
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 MAJ40X15-10S FAQ
Push 628 N and pull 528 N at 0.5 MPa; push 880 N and pull 739 N at 0.7 MPa; theoretical ceiling 128.1 kgf at 1.0 MPa. Operating pressure 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, 40 um filtered air, speed 30-800 mm/s, temperature -20 to +70 C.
The 40 mm bore uses 1/8" ports, with G and NPT thread codes available besides the standard PT. Mount via FA flange or LB foot, and I or Y rod knuckles fit the 16 mm rod, which is male-threaded M12x1.25.
