About the Airtac MIC Cushioned Mini Cylinder MIC40X50SU
Delivering serious thrust for a compact frame, this double-acting round-body mini cylinder pairs a stainless-steel barrel and rod with a needle-set air cushion at both ends. Tuning the cushion lets you decelerate heavy 50 mm strokes smoothly, protecting machinery from end-of-travel shock. The riveted build resists mild corrosion and washdown environments.
At the top of the MIC range, the 40 mm bore uses a 1/4 inch port and a 16 mm rod to generate 628.3 N of push force at 0.5 MPa. In practical terms, this translates to a safe working load of roughly 377 N, or lifting about 32 kg vertically with a 2:1 safety margin. The built-in -S magnet supports CMSG, DMSG and EMSG sensors for position feedback.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X50SU Is Used
Vertical Load Lowering
Manages roughly 32 kg vertical payloads with a 2:1 margin, using the adjustable cushion to prevent slamming at the bottom of the 50 mm stroke.
High-Speed Diversion
Pushes heavy packages rapidly on packaging lines where the 628.3 N thrust at 0.5 MPa moves items securely without end-of-stroke bounce.
Washdown Actuation
The stainless steel round-body construction provides mild corrosion resistance for food or lab environments requiring frequent cleaning.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X50SU the Right Cylinder?
Choosing this 40 mm bore makes sense when the 563.0 N push force of a MIC32 at 0.5 MPa is insufficient for your payload. Since there is no larger MIC frame, moving up requires a different cylinder family entirely. The adjustable air cushion is essential if you are cycling at high speeds near the 800 mm/s limit with heavy loads, as it prevents harsh impacts. Remember the cushion only decelerates the piston near stroke end; it does not function as a brake. For holding a load vertically during air loss, install an external rod lock or pilot check valve.
This SKU features a U-type back cover for 90-degree port orientation and mounting flexibility. You can pair it with LB foot, FA flange, SDB pivot, or TC trunnion brackets. Because it carries the -S suffix, it is ready for CMSG, DMSG or EMSG switches.
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 MIC40X50SU FAQ
This double-acting cylinder has a 40 mm bore, 50 mm stroke, 1/4 inch port, and a 16 mm rod with an M12x1.25 male thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, or 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa, and it operates at speeds from 30 to 800 mm/s.
No, the adjustable air cushion only decelerates the piston near the stroke end to reduce shock; it is not a lock or brake, and the piston will drift on air loss. You need an external rod lock or pilot check valve for load holding. It does include a -S piston magnet for use with CMSG, DMSG, and EMSG sensors.
