The AirTAC Airtac MA Mini Cylinders MA16X40SU is a genuine double acting standard round-body mini air cylinder with a Ø16mm bore and 40mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
A double-acting round-body mini cylinder from AirTAC, the MA16X40SU pairs a 16 mm stainless barrel with a 40 mm stroke and a flat-end U back cover. At 0.5 MPa it pushes 100.5 N (86.4 N pulling); at 0.7 MPa those figures climb to 140.7 N and 120.9 N, with a theoretical ceiling of 20.5 kgf. Fixed anti-impact pads soften the stroke-end knock - they decelerate only, they are not an adjustable cushion, and the rod will drift if supply air is lost.
Work the numbers before sizing: plan for about 60 N of real output at 0.5 MPa rather than the full 100.5 N rating, which is enough to lift roughly 5 kg vertically with a 2:1 margin (10 kg theoretical). The riveted stainless tube and 6 mm hard-chrome rod tolerate washdown and humidity far better than painted mini cylinders, and the built-in magnet takes CMSG, DMSG or EMSG switches as a standard fit. Supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.

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.

| -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.
Flips a reject chute on a tablet blister line; 100.5 N push at 0.5 MPa easily kicks a lightweight sealed card off the track.
Clamps a small reagent tray on an analytical sampler where the stainless barrel tolerates repeated wipe-down with cleaning fluid.
Drives a probe that confirms a cap is seated on a 30 ml bottle; the built-in magnet feeds a CMSG switch signal to the PLC.
Cross-check the force class before ordering: the next bore up, 20 mm, gives 157.0 N push at 0.5 MPa versus 100.5 N here, while 25 mm reaches 245.3 N. Port on this 16 mm bore is M5x0.8 and the male rod thread is M6x1.0. The U flat-end cover fixes straight to a plate - choose CA pivot or CM round end instead if the load swings. Keep in mind a plain MA cannot hold position once the valve centres; add a rod lock or pilot check valve for hanging loads. Standard strokes run to 500 mm; anything beyond is made to order.
Quick checklist
Push at 0.5 MPa is 100.5 N and pull 86.4 N; at 0.7 MPa push is 140.7 N and pull 120.9 N, with a theoretical 20.5 kgf maximum at 1.0 MPa. It is double-acting with a 6 mm rod, M5x0.8 port, M6x1.0 rod thread, 0.15-1.0 MPa (22-145 psi) pressure range and 30-800 mm/s speed.
The barrel is high-precision stainless steel rolled onto aluminium-alloy covers, and the 6 mm piston rod is hard-chrome plated carbon steel, so condensation and mild washdown cause little harm. Fixed bumper pads cushion the stroke ends - they absorb impact but are not adjustable air cushions; that function belongs to the MAC series.
