The AirTAC Airtac MA Mini Cylinders MA16X50SU is a genuine double acting standard round-body mini air cylinder with a Ø16mm bore and 50mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Light-duty precision is where the MA16X50SU lives: the smallest MA bore, 16 mm, pushing 100.5 N at 0.5 MPa over a 50 mm stroke, double acting on 0.15-1.0 MPa (22-145 psi) air. Its M5x0.8 ports suit compact manifolds and small valve plates.
Even at this size the build is serious - a precision stainless barrel, a 20 um hard-chrome rod and rolled aluminium covers forming a sealed round body that survives damp, dusty corners. Fixed bumper pads tame stroke-end impact without needing adjustable cushioning. Realistically, plan on about 60 N of working push at 0.5 MPa - around 5 kg of vertical lift with a 2:1 margin. The magnet is factory installed, so CMSG, DMSG and EMSG switches attach directly.

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.

|---|---|
| 16 | Bore size in mm. |
| ×50 | Stroke length in mm. |
| -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.
Rejected blister cards are flicked off the inspection track into a reject bin; 100.5 N at 0.5 MPa is ample for these few-gram items, and the M5x0.8 ports suit the compact manifold.
The rod nudges a limit lever to confirm gate closure; a CMSG switch on the built-in magnet reports cylinder position to the PLC.
Finished bushings are pushed from their dial-table pockets into a chute; the stainless barrel shrugs off cutting-fluid mist around the station.
As the smallest bore in the range it has no lower neighbour; stepping up to 20 mm lifts push from 100.5 N to 157 N at 0.5 MPa, and 25 mm to 245.3 N. The 50 mm travel suits sensing probes and light ejection; guide the load externally so the 6 mm rod sees no side force. With no air applied the rod slides freely - a rod lock or pilot check valve is the answer where a held position matters. U flat-end cover for simple through-fixing, FA flange or LB foot for rigidity, SDB bracket for pivot points; rod thread is M6x1.0.
Quick checklist
At 0.5 MPa: 100.5 N push, 86.4 N pull. At 0.7 MPa: 140.7 N push, 120.9 N pull. Theoretical maximum is 20.5 kgf at 1.0 MPa. Double acting, 30-800 mm/s, 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, 6 mm rod with M6x1.0 male thread, M5x0.8 ports.
Every MA16X50SU includes a built-in piston magnet as part of the standard specification. Clip a CMSG, DMSG or EMSG reed switch into the barrel groove and wire it to your PLC for end-of-stroke or mid-stroke confirmation.
