Airtac MAC Stainless Steel Mini Air Cylinder MAC25X105SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X105SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 105mm 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 MAC25X105SCA
Pivot work suits the MAC25X105SCA: the CA back cover provides a rear pivot, so a swinging arm or tilting link connects without an extra bracket. Inside is the familiar round-body build - stainless barrel, hard-chrome plated rod, aluminium covers rolled onto the tube - running double acting with a variable cushion at both ends.
The 25 mm bore pushes 245.3 N at 0.5 MPa and 343.4 N at 0.7 MPa, with 206.1 N of pull at 0.5 MPa. Treat about 147 N as the working force at 0.5 MPa; that equals roughly 25 kgf of lift, or 12 kg when you keep a 2:1 vertical margin. Supply is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, temperature -20 to +70 C.

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 MAC25X105SCA Is Used
Hopper gate tilt
Pivots a slide gate on a small grain hopper to batch feed a bagger; 245.3 N at 0.5 MPa shears through bridged product without jarring the frame.
Oven tray flip arm
Tips baking trays onto a cooling conveyor at a bakery line; the rear pivot tracks the arc and both cushions soften the catch at full tilt.
Chute deflector swing
Swings a deflector chute at an aggregate screening station to split gravel between two bins; the 105 mm stroke matches the existing linkage.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X105SCA the Right Cylinder?
Sizing check: 157.0 N at 0.5 MPa from a 20 mm bore covers light gates; 402.2 N at 0.5 MPa from a 32 mm bore covers heavier tilting loads. The 105 mm stroke is within the 500 mm standard range for the 25 mm bore, so no custom barrel is needed.
With a pivot back cover and a 105 mm stroke, keep the load in line with the rod axis - side loads bend the 10 mm rod and wear the seals; an I or Y rod knuckle absorbs small misalignment. The standard magnet pairs with CMSG, DMSG or EMSG switches for end-of-travel signals. Remember the piston moves freely when air is lost; fit a pilot check valve or rod lock where a tilted arm must stay put.
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 MAC25X105SCA FAQ
For the 25 mm bore: push 245.3 N and pull 206.1 N at 0.5 MPa, push 343.4 N at 0.7 MPa, and a theoretical maximum of 50 kgf at 1.0 MPa. Size the mechanism on about 60 percent of the 0.5 MPa push, roughly 147 N. Operating band is 0.15-1.0 MPa (22-145 psi) and rod speed 30-800 mm/s.
The CA option integrates the pivot into the rear cover, so a linkage or swing arm pins straight to the cylinder instead of through a separate bracket. Combine it with the standard magnet - CMSG, DMSG or EMSG switches clamp onto the stainless barrel to signal retracted and extended positions across the 105 mm stroke. FA flange and LB foot accessories are available if a fixed point is also needed.
