The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X75-10S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø16mm bore and 75mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Stainless where it counts: the MAJ16X75-10S wraps a hard-chrome carbon-steel rod in a stainless round barrel, riveted to aluminium covers for a compact 75 mm stroke you can shorten by up to 10 mm at the stop screw. It drives 100.5 N at 0.5 MPa, so keep design loads near 60 N; halving the 10 kg theoretical lift leaves about 5 kg of vertical margin. Operating band 0.15-1.0 MPa (22-145 psi), 30-800 mm/s.
Sensing is wired up simply because the magnet is part of the standard build - CMSG, DMSG and EMSG switches fit without ordering a special piston. The bumper pads are fixed anti-impact elements, softer landings rather than adjustable cushions like the MACJ range, and the round riveted body slots into cramped machine frames better than a profile block.

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. |
| ×75 | 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.
Pops up a stop blade to singulate boards at the reflow infeed; the 10 mm trim aligns the blade to the rail height.
Lifts about 5 kg jig plate vertically with a 2:1 margin from the 100.5 N rating; guide the 6 mm rod externally to avoid side load.
Ejects a CNC tool-setter drawer after unlock; bumper pads stop the drawer gently instead of slamming it home.
With 100.5 N push and 86.4 N pull at 0.5 MPa, this Dia 16 unit handles light work; bore 20 raises push to 157.0 N when parts get heavier. The 10 mm adjust window is for final trim, not continuous re-gapping. The end screw positions the extend stroke but cannot immobilise the piston on air loss, so use an external brake where safety demands it. Magnet is built in, so CMSG / DMSG / EMSG switch placement is free of special orders. FA flange and LB foot mounts, plus I or Y knuckles; M5x0.8 ports, M6x1.0 rod thread. Keep the 6 mm rod straight: guiding the load externally preserves the 30-800 mm/s speed rating and the bumper's life.
Quick checklist
Design numbers: 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 force at 1.0 MPa. The 75 mm stroke trims 10 mm at the stop screw; supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, M5x0.8 ports, M6x1.0 rod thread.
FA flange and LB foot mounting are available, with I or Y rod knuckles for the accessory end. Because the magnet is standard, CMSG, DMSG and EMSG switches mount directly on the stainless barrel for end-of-stroke signalling.
