About the Airtac MIC Cushioned Mini Cylinder MIC40X500U
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy duty cycles. The stainless-steel barrel and rod resist mild corrosion, making it suitable for washdown environments. It features a 1/4 inch air port and a 500 mm stroke, utilizing a U-style 90-degree rear cover for specific mounting orientations.
A defining trait of the MIC series is the adjustable air cushion at both ends. By turning a needle valve, you tune the deceleration to absorb high-speed end-of-stroke shock, protecting the load and lowering noise compared to a fixed bumper. This base SKU lacks a magnet and cannot accept position sensors; the -S variant is required for CMSG, DMSG, or EMSG switches.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø40 bore is a larger, non-ISO-6432 size.
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 MIC Cushioned Mini Cylinder MIC40X500U Is Used
Heavy Package Diversion
Pushes heavy cartons at high speed across sorting lines, relying on the adjustable air cushion to softly stop the 500 mm stroke without slamming.
Pallet Flap Folding
Folds large cardboard flaps on packaging machinery where the 628.3 N push force easily overcomes stiff material resistance.
Vertical Gate Actuation
Raises and lowers access gates on automated storage systems, benefiting from the stainless build in mildly humid warehouse conditions.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X500U the Right Cylinder?
When sizing this 40 mm bore, dropping down to a MIC32 yields 402.2 N of push force at 0.5 MPa, while no larger MIC bore exists. Choose this model for heavy loads moving at high speeds where the adjustable cushion is essential to prevent impact damage. It provides a safe working load of about 377 N and lifts roughly 32 kg vertically with a 2:1 safety margin.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a brake. If you need to hold a load vertically during air loss, install an external rod lock or pilot-operated check valve. For mounting flexibility, the cylinder supports LB foot, FA flange, SDB pivot, and TC trunnion brackets.
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 MIC40X500U FAQ
This 40 mm bore cylinder has a 1/4 inch port and a 500 mm stroke. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must select the -S version to use CMSG, DMSG, or EMSG switches. The adjustable air cushion and stainless steel construction are standard on this model.
