Airtac MAC Stainless Steel Mini Air Cylinder MAC25X85SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X85SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 85mm 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 MAC25X85SCM
A rounded CM back cover is formed into this 25 mm bore cylinder, giving the MAC25X85SCM a compact nose for pivot pins and link arms over its 85 mm stroke. Air drives the rod both ways - double acting with a variable cushion at each end - and at 0.5 MPa the push figure is 245.3 N against 206.1 N on retract.
Construction is the classic rolled stainless tube with a hard-chrome plated carbon-steel rod and aluminium covers, sealed by riveting rather than tie rods. The magnet comes fitted as standard, so CMSG, DMSG and EMSG switches mount on the barrel the day it arrives. For sizing: the 245.3 N push supports roughly 147 N of continuous real work at 0.5 MPa once the usual margin is kept.

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 MAC25X85SCM Is Used
Blister tray indexing
Advances blister trays one pocket at a time on a semi-automatic sealing line; the 85 mm pitch matches the machine index and the cushion finishes each step without a jolt.
Sample press station
Presses lids onto 40 ml sample vials in a QC lab, where about 147 N of steady working force at 0.5 MPa seats the caps without cracking the plastic.
Fixture stopper gate
Drops a steel stop into a machining fixture's escape path between cycles, with the standard magnet signalling full retract to the PLC through a DMSG switch.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X85SCM the Right Cylinder?
The MAC20X85 delivers 157 N at 0.5 MPa if your duty is light, while the MAC32X85 jumps to 402.2 N for stiffer loads; both share this round stainless body style. Anything held against gravity needs a rod lock or pilot check valve, because an unpowered MAC lets the piston float. Match the CM round-end to a pivot pin, add FA, LB or SDB hardware for fixed anchoring, and keep couplings square to the rod over the full 85 mm of travel to curb side thrust.
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 MAC25X85SCM FAQ
It pushes 245.3 N and pulls 206.1 N at 0.5 MPa, rising to 343.4 N and 288.5 N at 0.7 MPa, with a 50 kgf theoretical peak at 1.0 MPa. The bore 25 cylinder uses a 10 mm rod with M10x1.25 male thread and 1/8" air ports, the cushions at both ends are adjustable, and speed spans 30-800 mm/s.
The CM nose suits a pivot pin or linking rod, and where the machine needs fixed anchoring you can fit an FA flange, LB foot or SDB pivot bracket to the same body. On first commissioning, open both cushion needle screws fully and close them gradually until end-of-stroke thump disappears at your working speed.
