The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X30-10S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø16mm bore and 30mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
For tight envelopes where 30 mm of travel is all the machine offers, this bore 16 MAJ delivers 100.5 N at 0.5 MPa while an external stop screw trims the extend stroke down by 10 mm for exact part seating. It is double-acting: air extends and air retracts.
Inside, a two-way piston seal stores grease for long service, and the stainless-steel tube shrugs off the condensation common near washdown conveyors. The built-in magnet works with CMSG / DMSG / EMSG switches out of the box. For sizing, count on close to 60 N of productive force at 0.5 MPa - the same as lifting about 5 kg vertically with margin built in.

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.
| 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.
| MAJ | Standard round-body mini cylinder (adjustable-stroke). |
|---|---|
| 16 | Bore size in mm. |
| ×30 | Stroke length in mm. |
| -10 | Adjustable stroke window (mm the extend stroke can be shortened on site). |
| -S | Built-in magnet for CMSG / DMSG / EMSG sensors (standard on MA series). |
| CA / U / CM | Back-cover type: CA pivot, U flat-end, CM round-end. |
MA-family variants: MA / MAC (double acting ±cushion), MSA / MTA (single acting push / pull), MAD / MACD (double rod ±cushion), MAJ / MACJ (adjustable stroke ±cushion), MAR (cushioned with integrated F/U mount). Mounting accessories: FA flange, LB foot, SDB pivot; plus I and Y knuckles. Thread PT (blank) / G / NPT.
Clamping small circuit-board nests with 100.5 N at 0.5 MPa; the 10 mm trim seats each nest to a repeatable depth.
Nudging 96-well microplates off a reader tray with a short 30 mm stroke; bumper pads keep the motion quiet.
Toggling a flag for a photo-eye in compact assembly cells; the built-in magnet adds a second signal via a DMSG switch.
With a 30 mm stroke this model sits at the short end of the MAJ16 range, which runs to 300 mm standard; the same bore gives 100.5 N push and 86.4 N pull at 0.5 MPa. If your cycle needs more force, MAJ20 delivers 157 N at 0.5 MPa in a similar compact class. The 10 mm trim is set by the external screw and acts as an extend end-stop only - it will not hold a load if air is lost. FA flange or LB foot options fit the riveted round body, and the standard magnet accepts CMSG / DMSG / EMSG switches anywhere along the tube.
Quick checklist
Stroke length does not change bore force: 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, and 20.5 kgf theoretical maximum at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi); rod speed 30-800 mm/s.
Bore 16 uses an M5x0.8 port with an M6x1.0 male rod thread. The magnet is built in as standard, so CMSG, DMSG and EMSG switches mount directly on the stainless barrel for end-of-stroke or mid-stroke signals without any special-order piston.
