About the Airtac MIC Cushioned Mini Cylinder MIC40X40SUTC
Delivering 879.6 N of push force at 0.7 MPa, the AirTAC MIC40X40SUTC is a robust double-acting round-body mini cylinder built for demanding high-speed tasks. The stainless-steel barrel and Ø16 mm piston rod provide excellent mild corrosion and washdown resistance. A 1/4" port supplies the air, while the M12x1.25 male rod thread handles heavy mechanical connections. This 40 mm bore, 40 mm stroke configuration yields a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 safety margin.
Unlike standard bumper models, this unit features a variable air cushion at both ends. By turning a needle valve, you tune the end-of-stroke deceleration to eliminate shock and noise in fast cycles. The built-in -S piston magnet enables CMSG, DMSG, and EMSG sensor switches for precise position detection. It arrives configured with a U 90-degree rear cover and a TC trunnion mount for complex pivot articulation.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X40SUTC Is Used
High-Speed Diverters
Leverages the 879.6 N push force to push heavy cartons off a fast belt, using the adjustable air cushion to silently stop the 800 mm/s stroke without slamming.
Case Erector Jaws
Handles the repetitive opening of large packaging flaps, where the stainless build resists washdown chemicals and the 1/4" port delivers rapid actuation.
Pallet Load Pushing
Utilizes the 32 kg vertical lift capacity to shift heavy goods on a TC trunnion pivot, smoothly decelerating the heavy payload at stroke end to protect the assembly.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X40SUTC the Right Cylinder?
When sizing this 40 mm bore actuator, compare its 628.3 N push force at 0.5 MPa against the adjacent 32 mm bore, which provides 402.2 N. If your application requires even more power, there is no larger MIC bore available, making this the top force option in the series. The adjustable air cushion is essential when moving heavy loads at high speeds up to 800 mm/s, as it prevents destructive impact forces.
Remember that the cushion only decelerates the piston near the stroke end; it does not function as a brake. If the air supply drops, the piston will drift, so you must add an external rod lock or pilot-operated check valve to hold a suspended load safely. The TC trunnion accessory pairs with the U back cover to support pivoting loads, while the -S magnet allows seamless sensor integration.
Quick checklist

- ✓ 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 MIC40X40SUTC FAQ
This 40 mm bore cylinder features a 1/4" air port and an M12x1.25 male rod thread. At 0.5 MPa it provides 628.3 N push and 527.8 N pull force. At 0.7 MPa it delivers 879.6 N push and 738.9 N pull. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, the adjustable air cushion only decelerates the piston near the end of the stroke to reduce shock; it is not a locking brake. If air pressure drops, the piston will drift. To hold a load securely, you must install an external rod lock or a pilot-operated check valve.
