The AirTAC Airtac MA Mini Cylinders MA20X200SCA is a genuine double acting standard round-body mini air cylinder with a Ø20mm bore and 200mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Two hundred millimetres of stroke on a 20 mm bore makes the MA20X200SCA a long-reach pusher in a slim stainless tube. It is double acting - air both extends and retracts the 8 mm rod - and fixed bumper pads soften the piston's arrival at each end rather than acting as an adjustable cushion. Force at 0.5 MPa is 157.0 N push and 131.9 N pull; at 0.7 MPa push climbs to 219.8 N, and the theoretical peak is 32.0 kgf at 1.0 MPa.
For day-to-day sizing, plan on roughly 94 N of working push at 0.5 MPa - about 16 kg lifted straight up at full rating, or 8 kg with a 2:1 margin. The rolled stainless barrel shrugs off washdown and humidity, and the built-in magnet lets CMSG / DMSG / EMSG switches signal position with no special piston.

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.

| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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.
A 200 mm advance moves one tray pitch per cycle at 157 N, comfortably fast within the 30-800 mm/s speed band.
Opens a sliding machine-guard panel at shift change; the CA pivot eye absorbs the door's arc without side-loading the rod.
About 94 N of practical push nudges small parcels off a belt into a chute, with a DMSG sensor confirming the retract position.
Down-size to the 16 mm bore (100.5 N push at 0.5 MPa) for lighter duties, or up-size to the 25 mm bore (245.3 N) when the job grows. At 200 mm of stroke, side loads matter: guide the load externally and keep thrust in line with the rod, or the 8 mm rod will see bending it was not designed for. The piston coasts freely when air is lost - bumpers cushion, they do not hold - so a pilot check valve or rod lock is the answer for suspended loads. CA pivot eye in the back cover, with FA flange / LB foot / SDB pivot brackets available; 1/8" ports and M8x1.25 rod thread.
Quick checklist
Push 157.0 N, pull 131.9 N at 0.5 MPa; push 219.8 N, pull 184.7 N at 0.7 MPa; theoretical maximum 32.0 kgf at 1.0 MPa. Double acting, fixed bumper pads, 0.15-1.0 MPa (22-145 psi) supply, 30-800 mm/s speed, 1/8" ports, 8 mm rod with M8x1.25 thread.
The stainless barrel and hard-chrome plated rod handle the span, but long strokes amplify side load, so guide the payload externally and mount the cylinder so thrust stays axial - the CA pivot, FA flange, LB foot or SDB pivot options cover most layouts.
