About the Airtac MIC Cushioned Mini Cylinder MIC40X450CM
Delivering robust motion for demanding setups, the AirTAC MIC40X450CM is a double-acting round-body mini cylinder built with a stainless-steel barrel and rod to resist mild corrosion and washdown environments. A 1/4 inch port feeds the 16 mm piston rod, driving a 628.3 N push force at 0.5 MPa. The CM round rear cover provides a clean mounting footprint for this 450 mm stroke unit.
The defining trait of the MIC family is the needle-adjustable air cushion at both ends, which soaks up high-speed end-of-stroke shock to protect your load and cut noise. For sizing, this bore yields a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 margin. Note this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X450CM Is Used
Heavy Carton Diversion
Uses the 628.3 N push force to deflect heavy packaged goods on a high-speed sorting line, relying on the adjustable cushion to prevent end-stroke impact damage.
Vertical Material Lowering
Safely lowers a 30 kg fixture down a 450 mm path, using the needle-set air cushion to smooth the final deceleration before the CM cover base.
Washdown Gate Actuation
Shifts a heavy access panel in a humid food-grade zone, benefiting from the stainless-steel rod and barrel construction for mild corrosion resistance.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X450CM the Right Cylinder?
When configuring this 40 mm bore, sizing both ways is critical. Stepping down to the MIC32 bore drops the 0.5 MPa push force to 402.2 N, while the 40 mm bore provides 628.3 N. There is no larger MIC bore available, so for loads exceeding the 879.6 N push capacity at 0.7 MPa, a different cylinder family is required. The adjustable cushion is essential when cycling at high speeds or moving heavy masses.
Because this is a non-magnetic SKU, position sensing is unavailable unless you upgrade to the -S variant for CMSG, DMSG or EMSG switches. Remember the air cushion only decelerates the piston near the stroke end; it does not lock or hold the load. If air pressure drops, the piston will drift, so fit an external rod lock or pilot check valve for suspended loads. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion.
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 MIC40X450CM FAQ
This 40 mm bore cylinder features a 1/4 inch port and a 16 mm rod. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 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.
No, this specific SKU does not include a magnet and cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for sensing. The adjustable air cushion at both ends only decelerates the load near stroke end and does not act as a brake.
