About the Airtac MIC Cushioned Mini Cylinder MIC32X40SU
Delivering 563 N of push force at 0.7 MPa, this double-acting round-body mini cylinder handles demanding short-stroke tasks. The MIC32X40SU features a stainless-steel barrel and piston rod, offering mild corrosion resistance for washdown or humid settings. A 1/8 inch port feeds the 12 mm rod, while the U-style back cover provides a 90-degree mounting orientation for tight spatial constraints.
Unlike basic bumper models, this unit integrates an adjustable air cushion at both ends. You tune a needle valve to decelerate the piston near stroke end, effectively absorbing high-speed kinetic energy to lower shock and noise. The built-in -S magnet enables position sensing with CMSG, DMSG, or EMSG switches. Based on the 402.2 N push force at 0.5 MPa, it yields a safe working load of roughly 241 N, lifting about 20.5 kg vertically with a 2:1 margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC32X40SU Is Used
High-Speed Diverting
Uses the 563 N thrust to push packages off a belt at speed, with the adjustable air cushion preventing harsh impacts that could damage the diverter arm.
Carton Flap Folding
Drives a folding mechanism at 800 mm/s where the needle-set cushion softly decelerates the 12 mm rod, avoiding crushed cardboard on the stroke end.
Light Pressing Tasks
Applies a steady 241 N safe working load to seat small bearings, leveraging the stainless build to resist coolant mist in machining centers.
Is the Airtac MIC Cushioned Mini Cylinder MIC32X40SU the Right Cylinder?
When sizing this 32 mm bore, stepping down to a MIC25 bore drops the 0.5 MPa push force to 245.3 N, whereas stepping up to a MIC40 bore raises it to 628.3 N. Choose this 40 mm stroke variant when your application demands high cycling speeds and the adjustable air cushion is required to prevent end-of-stroke banging. The cushion only decelerates the load; it does not function as a brake. If you need to prevent drift on air loss, install an external rod lock or pilot check valve. Pair the -S magnet with CMSG, DMSG, or EMSG sensors for switching, and utilize the U back cover for 90-degree mounting.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
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 Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MIC Cushioned Mini Cylinder MIC32X40SU FAQ
This double-acting cylinder uses a 1/8 inch port and a 12 mm rod. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
No, the adjustable air cushion only decelerates the piston near the stroke end and never acts as a lock or brake; use a pilot check valve for holding. The -S designation means a magnet is built in for use with CMSG, DMSG, or EMSG switches.
