Airtac MAC Stainless Steel Mini Air Cylinder MAC25X230SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X230SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 230mm 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 MAC25X230SCM
Machine-guard sliders and long clamp rails are natural territory for this model: 230 mm of travel from a 25 mm bore that still generates 245.3 N at 0.5 MPa, rising to 343.4 N at 0.7 MPa. Fed with 0.15-1.0 MPa (22-145 psi) air it sweeps between 30 and 800 mm/s, and the variable air cushion at each end is dialled in with the needle screws so full-speed stops stay quiet.
The CM round-end back cover here is machined to take a pivot pin, letting the cylinder articulate inside a linkage without bolted-on adapters. Around that joint, the stainless tube and hard-chrome plated rod resist corrosion in damp plant air, while the built-in magnet feeds position signals to CMSG, DMSG or EMSG switches along the barrel. For sizing, treat roughly 12 kg as the vertical load this rod can lift with a 2:1 pressure margin.

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 MAC25X230SCM Is Used
Guard-slide drive
Opens and closes a sliding polycarbonate guard on a press brake, magnet switches confirming the safe-open position.
Rack indexer
Steps a storage rack shuttle one position per cycle across a 230 mm pitch, cushion stops protecting the frame.
Workbench clamp arm
Holds long workpieces against a jig fence in a joinery shop, 245.3 N of clamping force keeping timber square during routing.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X230SCM the Right Cylinder?
Drop to a 20 mm bore (157 N at 0.5 MPa) if the guard or rail is light; go to a 32 mm bore (402.2 N) for heavier slide doors. Since the MAC is double acting with no internal lock, any vertical or gravity load will creep once air is removed - specify a rod lock cylinder or an external check valve for those positions. Bolt on LB feet, an FA flange or an SDB pivot bracket to suit the frame, and consider an I or Y rod knuckle for pivoting linkages; across a 230 mm stroke, guide the load externally so the rod sees minimal side force.
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 MAC25X230SCM FAQ
Push force is 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa it is 343.4 N push and 288.5 N pull, peaking at 50 kgf theoretical at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), stroke speed 30-800 mm/s, and the port size is 1/8".
It provides a rounded rear boss that accepts a pivot pin, so the cylinder can swing in a linkage or clevis without extra brackets. Combine it with FA flange, LB foot or SDB body mounts, and clip a CMSG, DMSG or EMSG switch onto the magnet-equipped barrel for end-of-stroke detection.
