About the Airtac MIC Cushioned Mini Cylinder MIC20X25CM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless steel round-body mini cylinder is built for rapid actuation. The 20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread. Its defining feature over standard bumpers is the adjustable air cushion at both ends, letting you dial in needle settings to absorb end-of-stroke shock at high speeds. The CM round rear cover provides a clean back-end profile for compact assemblies.
Designed to drop into standard mini brackets via its ISO 6432 mounting interface, the stainless barrel and rod resist mild corrosion and washdown environments. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 94 N, lifting about 8 kg vertically with a 2:1 safety margin. Note this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors without switching to the -S variant.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X25CM Is Used
Package Diverting
Rapidly pushes light parcels on a sorting line where the 94 N safe working load is sufficient and the dual air cushions prevent harsh slams during fast cycling.
Small Part Ejection
Ejects molded components from a machine bed, using the 157 N push force to clear parts quickly while the needle-set cushions soften the abrupt end stop.
Flap Folding
Folds cardboard flaps on a compact packaging jig, benefiting from the stainless build for mild washdown resistance and the CM rear cover for tight clearances.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X25CM the Right Cylinder?
When sizing this 20 mm bore, dropping down to the 16 mm version reduces the 0.5 MPa push force to 100.5 N, while stepping up to the 25 mm bore increases it to 245.3 N. Choose this 20 mm class when you need that 157 N thrust at high cycling speeds where the adjustable air cushion prevents harsh impacts. It operates between 30 and 800 mm/s.
Keep in mind the air cushion only decelerates the load near the stroke end; it does not function as a brake or lock. If your application must hold position on air loss, add an external rod lock or pilot check valve. For mounting flexibility, you can utilize LB foot, FA flange, SDB pivot, or TC trunnion brackets alongside CA, U, R, or CM back covers.
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 MIC20X25CM FAQ
This 20 mm bore cylinder features a 1/8 inch port, an 8 mm rod, and an M8x1.25 male thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, or 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 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 cushions at both ends only serve to decelerate the load near stroke end, not to hold it.
