The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X175-10S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø16mm bore and 175mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Indexing moves that need only a small end tweak suit the MAJ16X175-10S: a 175 mm stroke with a 10 mm extend-trim window set by an external stop screw. Output at 0.5 MPa is 100.5 N push and 86.4 N pull, climbing to 140.7 N at 0.7 MPa; the theoretical ceiling at 1.0 MPa is 20.5 kgf. The stainless round barrel rolled onto aluminium covers keeps the body compact and rust-resistant in damp or washed-down corners.
In practice that is about 60 N of usable push at 0.5 MPa, or a vertical lift near 5 kg once the 10 kg theoretical figure is halved for a 2:1 margin. A fixed bumper pad takes the sting out of stroke ends - it decelerates only, so for adjustable cushioning you would step up to the MACJ type instead. Every MA cylinder carries its magnet as standard, letting CMSG / DMSG / EMSG switches drop on out of the box.

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.

| 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.

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.
Fires stamped shims clear of a small punch die between strokes; 100.5 N at 0.5 MPa is ample for gram-weight parts, and the 10 mm trim dials in the exact ejection height.
Advances sample racks along a laboratory analyser transport lane, with the built-in magnet and a CMSG switch confirming rack-present at each station.
Raises a vision-inspection camera 175 mm clear of the pass line between batches, keeping a 2:1 margin by limiting the head to about 5 kg against the 10 kg theoretical lift.
At 175 mm the 6 mm rod is slender, so guide the load externally and keep side thrust off the rod. If 100.5 N at 0.5 MPa falls short, bore 20 pushes 157 N within the same mounting family. The 10 mm trim screw marks an end position, not a holding brake - with air off the piston creeps, so pilot a valve where holding matters. FA flange and LB foot mountings bolt straight on, and the standard magnet takes CMSG / DMSG / EMSG switches without a special-order piston.
Quick checklist
Figures for the 16 mm bore: 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. Working pressure is 0.15-1.0 MPa (22-145 psi) and the speed range is 30-800 mm/s.
The fixed bumper pad at each stroke end decelerates the piston to soften impact - it is a damper, not an adjustable air cushion (that is the MACJ family). The barrel is stainless steel rolled onto aluminium covers with a hard-chrome plated rod, so humid, washed-down or mildly corrosive areas are handled without paint flaking.
