The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X60-30S 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.
For builders who want one cylinder to serve several stop positions, the 30 mm window on the MAJ16X60-30S is the widest trim in the small-bore range: an external stop screw pulls the 60 mm extend stroke down as jobs change. Double-acting output is 100.5 N at 0.5 MPa - plan on about 60 N of real work - and 140.7 N at 0.7 MPa; vertically, the 0.5 MPa rating equals roughly 10 kg, so halve that to about 5 kg for a safe lift.
The stainless round barrel with its 20 um hard-chrome rod shrugs off moisture in food-adjacent and outdoor cells, the riveted aluminium covers keep the body compact, and fixed bumper pads calm the stroke end. A piston magnet ships standard for CMSG, DMSG or EMSG switches.

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.

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.
Ejects small cartons from a picking shuttle; the 30 mm window re-tunes throw depth as tote sizes change across shifts.
A stainless body copes with washdowns and humidity in automated guided vehicle charging bays while a CMSG switch confirms door-open.
The trimmed 30-60 mm extend range compresses light springs in a quality bench fixture, with stroke depth changed between part numbers.
At the 16 mm bore you get 100.5 N push at 0.5 MPa; the next bore up (20 mm) reaches 157 N, so move there if your clamp needs more than the roughly 60 N this size comfortably delivers over its 30-800 mm/s speed span. The wide 30 mm trim suits fixture families where stop height varies by tens of millimetres.
Because the adjuster is only an extend-direction end stop, a load can still sag if pressure is cut - add a valve or external stop for true holding. Mount with the FA flange or LB foot, thread sensors on via the standard magnet, and keep side loads off the 6 mm rod across the longer part of the stroke.
Quick checklist
Rated 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N and 120.9 N at 0.7 MPa, peaking at 20.5 kgf theoretical at 1.0 MPa. For real work budget around 60 N at 0.5 MPa, which corresponds to lifting roughly 5 kg vertically with a 2:1 margin. The extend stroke trims by up to 30 mm via the external stop screw.
No. Fixed bumper pads decelerate the piston near each stroke end, but they cannot be tuned like a cushion. If the machine needs adjustable air cushioning, the AirTAC MACJ variant pairs a similar adjustable stroke with end cushions; the MAJ sticks to simple, maintenance-free pads.
