The AirTAC Airtac MA Mini Cylinders MA25X75SCAG is a genuine double acting standard round-body mini air cylinder with a Ø25mm bore and 75mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Made for machine builders whose plumbing follows the G (BSPP) standard, this double-acting mini cylinder carries parallel G1/8 ports that seal on a bonded face washer instead of the thread flanks, so no tape or pipe dope is needed at assembly. The riveted round body pairs a stainless-steel barrel with a hard-chrome plated carbon-steel rod, an outfit that shrugs off mild corrosion in damp food, washdown and outdoor cells where painted-steel minis pit early. Fixed anti-impact bumper pads soften both stroke ends; they decelerate only and are not an adjustable air cushion, which is the MAC family's territory. At 0.5 MPa the 25 mm bore develops 245.3 N of pushing force. Budget on about 147 N of that for real work and the cylinder still lifts roughly 12.5 kg vertically with a 2:1 margin, enough for capping heads, gate arms and small index mechanisms. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clip on without a special piston, and the CA pivot back cover lets the rod swing through its arc 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 | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 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.
Kicks off-spec bottles out of a checkweigher lane; 245.3 N at 0.5 MPa clears the arm with margin, and the stainless barrel tolerates splash-zone rinse-down.
Holds connector housings or PCB trays during press or solder steps; the roughly 147 N working force at 0.5 MPa matches delicate clamping without crushing.
The CA pivot back cover swings the rod through a door-opening arc on bakery and coating ovens, with the bumper pad catching the open-position stop.
Two sizes bracket this model: the 20 mm bore MA20 pushes 157.0 N at 0.5 MPa if the job is lighter, while a 32 mm bore delivers 402.2 N when the force margin needs to grow. Order this G-port build only when your manifold and fittings already follow BSPP; for North-American NPT plumbing pick the T variant, and for Rc tapered lines take the standard PT version. The CA pivot back cover handles swinging linkages directly, with FA flange, LB foot or SDB pivot brackets added when the frame demands a fixed mount. A plain MA will not lock its load: cut or centre the valve air and the piston drifts under gravity, so fit a rod lock or pilot check valve wherever a held position matters. At 75 mm travel the 10 mm rod carries axial loads comfortably, but still guide any off-axis tooling externally rather than through the rod.
Quick checklist
It is double acting with a 25 mm bore and 75 mm stroke, a 10 mm rod with M10x1.25 male thread and G1/8 BSPP ports. Thrust: 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push at 0.7 MPa, and a theoretical maximum of 50 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, and the position magnet is included.
G1/8 is a parallel BSPP thread that seals on a bonded face washer or O-ring seat rather than on the thread flanks, which suits European and Asian OEM manifolds fitted with BSPP couplings. NPT (T) and PT (Rc) tapered builds are ordered as separate variants; select the one that matches your existing fittings and manifold standard rather than adapting with bushings. Confirm exact port geometry from the datasheet when retrofitting.
