The AirTAC AirTAC MA16X30SU Mini Cylinder - 16 mm Bore U Back Cover is a genuine double acting standard round-body mini air cylinder with a Ø16mm bore and 30mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Small parts positioning gets a compact partner here: a 16 mm bore round-body mini cylinder with 30 mm stroke, double acting so air drives the rod out and back, with fixed anti-impact bumper pads softening each stroke end. At the shop-floor standard of 0.5 MPa it pushes 100.5 N, and about 60 N of that is a realistic budget for actual work once a margin is kept, while halving the rating still lets the rod lift roughly 5 kg vertically. The stainless-steel barrel and hard-chrome plated carbon rod (6 mm) shrug off splash and mild washdown far better than painted minis, and the riveted aluminium covers keep the body short and rigid. A magnet is built in as standard, so CMSG / DMSG / EMSG switches clamp straight on for end-of-stroke detection, and the U flat-end back cover bolts cleanly to a fixed plate without extra brackets.

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.

| 0.5 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.

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.
With about 60 N of practical work force at 0.5 MPa, the 6 mm rod flicks misaligned resistors or small trays off an SMT conveyor lane within the 30 mm travel, cycling at up to 800 mm/s.
Keeping a 2:1 margin, the rod raises roughly 5 kg vertically, enough for a small acrylic cover or shield on a manual packing station, and the magnet feeds a DMSG switch to confirm the open position.
A vision system triggers the valve, the bumper-padded stroke nudges a cracked cosmetic vial or serum bottle off the rail, and an EMSG switch wired to the standard magnet verifies retraction.
Bore 16 is the smallest in the MA range, so if 100.5 N at 0.5 MPa feels tight for the job, step up to the 20 mm bore, which delivers 157.0 N under the same pressure with an 8 mm rod. Remember this cylinder drifts freely the instant air is dropped or the valve centres, so clamping or held loads call for a pilot check valve or a rod lock. The U flat-end back cover suits fixed face mounting; FA flange, LB foot or SDB pivot brackets adapt it if the layout changes, and air connects through the M5x0.8 ports on both covers.
Quick checklist
At 0.5 MPa this 16 mm bore pushes 100.5 N and pulls 86.4 N; raise the supply to 0.7 MPa and push rises to 140.7 N. The theoretical ceiling is 20.5 kgf at 1.0 MPa. It is double acting with fixed bumper pads, runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, and carries a 6 mm rod with M6x1.0 male thread and M5x0.8 ports.
No. Every MA-series cylinder is supplied with the magnet already built in, so CMSG, DMSG and EMSG switches clamp directly onto the stainless barrel for end-of-stroke signals. Note the fixed bumper pads only damp stroke-end impact - they are not adjustable air cushions - and the rod will move freely if supply pressure is cut, so add a pilot check valve where a position must be kept.
