Airtac MAC Stainless Steel Mini Air Cylinder MAC25X5SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X5SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 5mm 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.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X5SU
In just 5 mm of travel the MAC25X5SU concentrates the full 25 mm bore force class: 245 N out, 206 N back at 0.5 MPa, scaling to 343 N at 0.7 MPa with a 50 kgf theoretical peak. This AirTAC round-body mini is double acting and cushioned at both ends, running on 0.15-1.0 MPa (22-145 psi) at speeds from 30 to 800 mm/s.
Its U flat-end cover presents two mounting ears for direct bolting to plates and channels - no pivot hardware in the way. The stainless barrel with a hard-chrome rod stands up to splash and humidity better than painted minis, and because the magnet is standard, CMSG, DMSG or EMSG switches signal that 5 mm stroke out of the box. For sizing, treat about 147 N as usable force at 0.5 MPa; vertically that is roughly 25 kg lifted, or halve it to 12 kg for a 2:1 safety factor.

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.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 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.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X5SU Is Used
Micro clamp
Locks small PCBs or lenses into test nests with a 5 mm clamp squeeze and cushioned final contact.
Stamp marker
Drives a light dot-peen or ink stamp head for a crisp 5 mm hit at up to 343 N on a 0.7 MPa supply.
Part presence kicker
Tips misloaded parts off a check station; the standard magnet confirms retract between every part.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X5SU the Right Cylinder?
Match the stroke to the job before the bore: 5 mm suits ejection kicks, presence checks and micro clamping, and this bore's 245 N at 0.5 MPa covers most of them - drop to a MAC20X5SU (157 N) for delicate parts or step to a MAC32X5SU (402 N) for stiff punches. The flat-end U cover wants a fixed base, with FA flange, LB foot or SDB pivot brackets as alternates. Note the rod is free to drift whenever air is removed from a plain cylinder, so add a rod lock where the 5 mm position must hold. Strokes beyond 500 mm would be made to order, but 5 mm sits deep inside the standard range.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAC Stainless Steel Mini Air Cylinder MAC25X5SU FAQ
Figures for the 25 mm bore: 245 N push and 206 N pull at 0.5 MPa; 343 N push and 288 N pull at 0.7 MPa; 50 kgf theoretical maximum at 1.0 MPa. Double acting, pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, with a variable air cushion at both ends.
The rolled stainless barrel with a 20 um hard-chrome plated rod resists corrosion and washdown better than painted or plain aluminium minis, and the riveted covers keep a tight, reliable seal. Add the standard piston magnet and CMSG, DMSG or EMSG switches drop on for position feedback.
