Airtac MAC Stainless Steel Mini Air Cylinder MAC25X35SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X35SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 35mm 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 MAC25X35SU
Flat-end U back cover, 25 mm bore, 35 mm stroke - the MAC25X35SU is the simplest way to bolt a cushioned mini straight into a machined slot. Double acting, it pushes 245.3 N and pulls 206.1 N at 0.5 MPa (22-145 psi), with a variable air cushion trimming shock at each end of travel.
Treat 147 N as the honest working push at 0.5 MPa; that is about 12.5 kg lifted vertically with a 2:1 margin. The riveted stainless round body and the hard-chrome 20 um rod plating resist corrosion in humid or washed-down corners, outlasting painted minis, and the standard piston magnet drops straight onto CMSG, DMSG or EMSG switch rails.

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 MAC25X35SU Is Used
Indexing stop on assembly conveyor
The U cover slots directly into a conveyor side rail, and the 35 mm stroke raises and lowers a stop pin between 245.3 N push cycles.
Vial crimping head
Benchtop crimpers use the flat end for a rigid toolplate mount, and the stainless body handles repeated alcohol cleaning.
Flip gate on a chute diverter
About 12.5 kg of vertical capability with a 2:1 margin flips lightweight diverter flaps, and cushioning keeps the flip quiet.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X35SU the Right Cylinder?
For 35 mm duties needing 245.3 N at 0.5 MPa, this sits above the MAC20X35 (157.0 N) and below the MAC32X35 (402.2 N). The U cover fixes flush; choose CM for round-end fixing or CA when the rod must pivot, and add LB foot, FA flange or SDB pivot hardware where the frame calls for it. M10x1.25 rod thread on a 10 mm rod, 1/8 inch ports. With air lost the rod moves freely, so a rod lock or pilot check valve is the fix for held loads.
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 MAC25X35SU FAQ
At 0.5 MPa: 245.3 N push, 206.1 N pull. At 0.7 MPa: 343.4 N push, 288.5 N pull. Theoretical ceiling 50 kgf at 1.0 MPa. Pressure window 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, 1/8 inch ports.
It gives a plain flat fixing face, so the cylinder drops into a slot or bolt hole pattern with no bracket. Mount alternatives: FA flange, LB foot, SDB pivot, or the CA pivot and CM round-end back covers on other order codes.
