The AirTAC Airtac B06-MAC Battery-Specific Cylinder B06-MAC16X25SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 25mm stroke, PT/G air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.
Flat-backed and compact, the U version of this 16 mm bore MAC bolts directly onto a machine plate through its flat-end cover, no adapter block needed. Stroke is 25 mm; force at 0.5 MPa is 100.5 N pushing and 86.4 N pulling, rising to 140.7 N and 120.9 N at 0.7 MPa. Double acting on both strokes with a variable cushion each end, it runs clean filtered air at 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s.
Treat about 60 N as the usable push at 0.5 MPa and the cylinder keeps margin over its working life - enough to clamp a light extrusion stop or snap a micro switch flag. The rolled stainless barrel and 20 um hard-chrome rod take repeated damp cycles without the flaking that plagues coated minis. CMSG / DMSG / EMSG switches read the standard magnet immediately, and the cushion needles open gradually after a fully backed-off start.

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 |

| 0.7 MPa | 0 N | 0 N |
| Max (@1.0 MPa) | 0 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 feeding machine gates parts behind timing screws; the flat-end cover sits flush against the frame and 100.5 N blocks the part flow positively.
A small X-Y positioning stage is locked by a wedge plunger driven 25 mm; the U cover anchors the cylinder straight to the stage base plate.
A benchtop labeller presses a roller down onto the web for 25 mm; the cushion lands the roller gently on the label stock without marking it.
Bore 16 is the entry force level; move to 157 N (bore 20) or 245.3 N (bore 25) at 0.5 MPa when the stop or clamp needs more muscle. Remember the rod is free once air is removed - a centred valve does not park it, so pilot check valves or a rod lock handle position-holding duties. For fixed mounting, the U cover plus FA flange or LB foot is the natural pair; SDB pivot suits a rocking base and CA or CM covers suit pinned links.
At 25 mm of travel the 6 mm rod sees little bending load, yet a guided load still pays off in seal life. Sensor feedback is included through the standard piston magnet.
Quick checklist
Push 100.5 N / pull 86.4 N at 0.5 MPa; push 140.7 N / pull 120.9 N at 0.7 MPa; 20.5 kgf theoretical peak at 1.0 MPa. The 16 mm bore uses M5x0.8 ports, the 6 mm rod carries an M6x1.0 thread, and the longest standard stroke in this bore is 500 mm.
No. Being double acting without a lock, the rod drifts once air pressure is removed or the valve centres. For a clamp that must hold, add a pilot check valve in the air lines or specify a rod lock; the cushions damp end-of-stroke impact only.
