The AirTAC AirTAC MA16X25SU Mini Cylinder 16 mm Bore PT is a genuine double acting standard round-body mini air cylinder with a Ø16mm bore and 25mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
A compact 16 mm entry in the MA round-body mini line, the MA16X25SU pairs a flat-end back cover with double-acting operation and fixed anti-impact bumper pads. At 0.5 MPa it delivers 100.5 N of push and 86.4 N of pull, and about 60 N of that is realistic working force once a margin is kept. That is roughly a 5 kg vertical lift at a 2:1 margin, enough to eject, index or clamp small parts. The riveted stainless barrel carries a 6 mm hard-chrome plated rod, so the body shrugs off the washdown and humidity that rust painted-steel minis. Ports are M5x0.8 and the magnet is built in as standard, letting CMSG / DMSG / EMSG switches drop on without special ordering. The U flat-end rear cover keeps the tail slim where brackets would steal space.

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.
The 100.5 N push at 0.5 MPa slides a finished circuit board cleanly off a needle-bed fixture in an electronics test cell, and the 25 mm stroke fits inside a slim jig frame.
On a small pharmaceutical bench this bore seats snap caps on 5 ml vials; planning around 60 N of usable force at 0.5 MPa keeps plastic caps from being crushed.
A 6 mm rod with a short stroke opens the sample-door flap on a compact analytical autosampler, and the stainless barrel handles the wipe-down cleaning routine of the bench.
Bore 16 is the smallest MA size, so sizing only goes one way up: if 100.5 N at 0.5 MPa runs short, the 20 mm MA reaches 157 N in just 4 mm more diameter. The short 25 mm stroke keeps the collapsed length minimal inside slim fixtures. Rear mounting is via the U flat-end cover; add FA flange, LB foot or SDB pivot brackets where the frame needs them, and match fittings to the M5x0.8 ports. With air removed the piston drifts freely, so a pilot check valve or rod lock is the fix where a part must stay clamped.
Quick checklist
At 0.5 MPa the MA16X25SU pushes 100.5 N and pulls 86.4 N; at 0.7 MPa those figures rise to 140.7 N and 120.9 N. The theoretical maximum at 1.0 MPa is 20.5 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
No. The MA carries fixed anti-impact bumper pads that soften the stop at each end of the 25 mm stroke; they decelerate but cannot be tuned, and they are not a load lock. Adjustable air cushioning belongs to the MAC family. Keep running speed within 30-800 mm/s.
