The AirTAC Airtac MA Mini Cylinders MA20X15SCA is a genuine double acting standard round-body mini air cylinder with a Ø20mm bore and 15mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
For tight spots that need a short, positive jab, the MA20X15SCA pairs a 20 mm bore with 15 mm of travel inside a riveted round barrel. Air drives the rod both ways (double acting) and produces 157 N of push at 0.5 MPa against a 0.15-1.0 MPa (22-145 psi) supply. The CA pivot back cover lets the body swing with its linkage, so no extra bracket is needed.
The high-precision stainless tube and hard-chrome plated carbon-steel rod (20 um) shrug off mild corrosion and washdown - a genuine edge over painted minis in damp or food areas. Fixed anti-impact bumper pads soften the stroke ends; they decelerate only and are not an adjustable air cushion. For sizing, count on about 94 N of usable work at 0.5 MPa, and the factory-fitted magnet means CMSG, DMSG or EMSG switches bolt on with no special-order 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.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 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.
The 15 mm throw drives a locking pin that secures the bottle-guide gate; 157 N at 0.5 MPa keeps the pin seated against line vibration, and the CA pivot follows gate swing.
Finished caps are nudged from the filling nest into a discharge chute; the stainless barrel and chrome rod stand up to the filler deck's daily washdown.
A CMSG switch dropped onto the standard magnet confirms full extension before the rotary table indexes, with speeds up to 800 mm/s.
At 15 mm this is a clamp-and-return actuator, so choose by force: bore 16 manages 100.5 N push at 0.5 MPa while bore 25 reaches 245.3 N - the MA20X15SCA splits them. Halving its 16 kgf rating leaves about 8 kg of safe vertical lift. If air is lost the piston drifts freely, so a rod lock or pilot check valve is required for held loads. Fix it with the CA pivot plus an SDB pivot bracket or I/Y knuckle, or switch to FA flange and LB foot for rigid mounting; rod thread is M8x1.25.
Quick checklist
At 0.5 MPa it pushes 157 N and pulls 131.9 N; raise the supply to 0.7 MPa and push climbs to 219.8 N (pull 184.7 N), with 32 kgf theoretical maximum at 1.0 MPa. It runs double acting at 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air, with an 8 mm rod, M8x1.25 male thread and 1/8 inch ports.
The pivot-style CA cover lets the cylinder swing with the mechanism, absorbing small misalignment without extra hardware. Combined with the riveted stainless round body it keeps the whole assembly short and compact for jigs, gates and small clamps.
