The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X60-50S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø16mm bore and 60mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Where a compact machine needs most of its travel trimmed by hand, this double-acting 16 mm unit shortens extension with an external stop screw anywhere in the ordered 50 mm window, keeping the full 60 mm retract. Output sits at 100 N push and 86 N pull at 0.5 MPa, climbing to 140 N push at 0.7 MPa on a 0.15-1.0 MPa (22-145 psi) supply.
A stainless rolled barrel with a hard-chromed 6 mm rod shrugs off splash and condensation better than painted aluminium minis, which suits humid bottling cellars and outdoor posts. Fixed bumpers decelerate the piston at each end; tunable cushioning lives in the MACJ family instead. Sizing for the long run, keep applied load around 60 N - enough headroom to raise a 5 kg part vertically with a 2:1 margin. The magnet is factory fitted, so CMSG, DMSG or EMSG switches mount without ordering options.

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. |
| ×60 | Stroke length in mm. |
| -50 | 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.
A tabletop conveyor hopper gate needs only part of the travel; the -50 window dials stroke per recipe while 86 N of pull resets the gate between totes.
On a manual glue station, technicians cut back extension by up to 50 mm so the 100 N nose feathers adhesive beads onto thin plywood without denting it.
Downstream of a filler, the 100 N push flicks under-filled 250 ml bottles off the line; the 30-800 mm/s speed band matches fast conveyor timing.
Compare across the family: the 20 mm bore gives 157 N push at 0.5 MPa if your mechanism runs short on force, while this 16 mm already covers 100 N and saves space. A 50 mm window on a 60 mm stroke leaves 10 mm of fixed extension - confirm your tooling can live with that minimum. Mount by FA flange or LB foot, add I or Y knuckles where the rod pivots, and rely on the built-in magnet for feedback. On air failure the stop screw keeps geometry but not the load; the piston will still sag.
Quick checklist
Expect 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 a theoretical maximum of 20.5 kgf at 1.0 MPa. Supply ranges 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speeds of 30-800 mm/s, an M5x0.8 port and a 6 mm rod.
Yes - every MA-series cylinder ships with the piston magnet already installed at no extra option code. Clip a CMSG, DMSG or EMSG switch onto the stainless barrel for end-of-stroke signaling; the riveted round body keeps the sensor seat stable through vibration.
