The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X175SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 175mm stroke, 1/8" 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.
Pushing 628 N at 0.5 MPa (and pulling 528 N) through a 175 mm stroke, the MAC40X175SU trades the pivot covers for a flat-end U back cover that bolts flat against machine plates. Underneath it is the standard MAC recipe: stainless round barrel, hard-chrome plated 16 mm rod, riveted aluminium covers, double acting with an adjustable air cushion at each end.
Expect a 32 kg vertical lift at a 2:1 margin - the full 628 N equates to about 64 kg - which covers most small-part handling. Operating window 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, with the magnet fitted as standard for CMSG / DMSG / EMSG switches.

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 | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

| 40 | Bore size in mm. |
| ×175 | Stroke length in mm. |
| -S | Built-in magnet for CMSG / DMSG / EMSG sensors (standard on MA series). |
| CA / U / CM | Back-cover type: CA pivot, U flat-end, CM round-end. |
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.
Opens and closes a slide gate under a small hopper of granules; the flat-end U cover mounts hard against the gate frame.
Lowers a probe or contact block onto PCB assemblies on an electronics test bench, cushioned so the touchdown stays gentle.
Presses a labelling or stamping head onto cartons at about 377 N of usable force, with the magnet triggering a CMSG switch at stroke end.
The 40 mm bore sits between the 32 mm (402 N push at 0.5 MPa) and the 50 mm (981 N), so scale in either direction by force rather than guesswork. The 1/8" ports take PT, G or NPT fittings per your code suffix. On a 175 mm stroke, check rod alignment at setup; bending loads on the 16 mm rod wear the front seal early, so add a guide or knuckle if the path is not straight. And because nothing in a plain MAC locks the piston, a de-energised valve lets the load drift - a rod lock or pilot check valve handles any holding duty.
Quick checklist
At 0.5 MPa: 628 N push, 528 N pull. At 0.7 MPa: 880 N push, 739 N pull. Theoretical maximum about 128.1 kgf at 1.0 MPa. Operating range 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), stroke speed 30-800 mm/s.
The rolled stainless-steel tube resists rust from condensation, washdown and outdoor air far better than painted steel, and the hard-chrome plated rod (20 um) adds a second barrier. It keeps the 40 mm bore sealing true over long duty in food, chemical or coastal plants.
