Airtac MAC Stainless Steel Mini Air Cylinder MAC40X65SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X65SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 65mm 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 MAC40X65SCA
Pivot-mounted minis save a bracket or two, and the CA back cover here is the pivot itself. The MAC40X65SCA pairs that with a 65 mm stroke on a 40 mm bore that pushes 628 N at 0.5 MPa, double acting, with a variable cushion trimming each end of travel.
Its stainless barrel resists the rinse chemicals that eat painted bodies, while the chrome-plated 16 mm rod keeps the seals running smooth through dusty shifts. De-rate to about 377 N for steady work - roughly a 32 kg vertical lift on a 2:1 margin. The standard built-in magnet means CMSG, DMSG or EMSG switches mount on the barrel without ordering a special piston.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MAC40X65SCA Is Used
Weld jig swing clamp
A clamp arm on an automotive bracket jig pivots parts under the torch, hung straight off the CA pivot cover.
Rotary table index stop
A pop-up stop drops into position between cycles on a transfer table, the cushion killing the landing bounce.
Lab vessel tilt cradle
A mixing vessel tilts on a pivot link for pouring, with the 32 kg lift margin covering a loaded 25 kg vessel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X65SCA the Right Cylinder?
If 402 N from a 32 mm bore covers the job, drop a size; take 981 N from 50 mm when you want headroom. Nothing is held when air is removed - the piston coasts - so add a rod lock or pilot check valve wherever a load must stay put. Run 0.15-1.0 MPa (22-145 psi) at 30 to 800 mm/s on 40 um filtered air. CA pivots suit linkages and lever arms; pick the U flat-end where a face bolt is cleaner or the CM round end for custom eyes. FA flange, LB foot and SDB brackets round out the mounting, and variants like MACD or MACJ cover double-rod or adjustable-cushion jobs later.
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 MAC40X65SCA FAQ
Rated push is 628.3 N and pull 527.8 N at 0.5 MPa on the 40 mm bore. Raise pressure to 0.7 MPa and push reaches 879.6 N, while the 1.0 MPa theoretical maximum is 128.1 kgf.
The barrel is a stainless tube with aluminium covers riveted over it, and the 16 mm carbon-steel rod is hard-chromed to 20 um. Painted bodies chip and corrode in washdown or outdoor air; this one rinses clean, which suits food plants and damp workshops.
