The AirTAC Airtac MA Mini Cylinders MA16X125SU is a genuine double acting standard round-body mini air cylinder with a Ø16mm bore and 125mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
The SU in MA16X125SU points to a flat-end U back cover on a 16 mm bore, 125 mm stroke round-body mini cylinder. Inside the stainless barrel sits a double-acting piston with fixed bumper pads that soften stroke-end impact; air drives the rod both out and back, with no spring anywhere in the circuit. At 0.5 MPa it pushes 100.5 N and pulls 86.4 N, rising to 140.7 N push at 0.7 MPa, and the theoretical ceiling is 20.5 kgf at 1.0 MPa.
Because the covers and stainless block are rolled onto the barrel, the body stays slim and resists mild corrosion in damp or washdown-prone corners where painted minis swell and flake. The built-in magnet ships as standard, so a CMSG, DMSG or EMSG switch bolts on for end-of-stroke signalling. Working numbers: count on about 60 N of practical push at 0.5 MPa, which is roughly lifting 10 kg straight up - or keep 5 kg if you want a 2:1 margin.

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.

| ×125 | 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.
Slides populated trays off a test fixture with 100.5 N of push, enough for a loaded magazine weighing a few hundred grams.
125 mm of travel reaches across a lab analyser deck; the standard magnet and a CMSG switch confirm each end position.
About 60 N of working force at 0.5 MPa seats small labels or glue dots without crushing the carton.
Sixteen millimetres is the smallest bore in the MA line, so size up rather than down: the 20 mm bore gives 157.0 N push at 0.5 MPa for about half again more force in the same family. Like every MA, the piston drifts when air is removed - the bumper pads decelerate, they do not lock - so fit a pilot check valve or rod lock if the load must stay put. The U flat-end cover takes a fixed mounting directly; add an FA flange, LB foot or SDB pivot bracket, plus I or Y rod knuckles on the 6 mm rod. Port is M5x0.8 and the rod thread is M6x1.0.
Quick checklist
Push 100.5 N and pull 86.4 N at 0.5 MPa; push 140.7 N and pull 120.9 N at 0.7 MPa; theoretical maximum 20.5 kgf at 1.0 MPa. It is double acting with fixed bumper pads, runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, speeds of 30-800 mm/s, M5x0.8 ports and a 6 mm rod with M6x1.0 male thread.
The rolled stainless barrel and the 20 um hard-chrome plated rod shrug off splash, humidity and mild washdown that rust painted mini cylinders; the riveted aluminium covers keep the body slim and sealed.
