Airtac MIC Cushioned Mini Cylinder MIC20X85SCA
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X85SCA is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 85mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MIC Cushioned Mini Cylinder MIC20X85SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder is built for high-speed actuation. The Ø20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread. Because it uses the ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises without profile rails or tie-rods. The stainless barrel and rod resist mild corrosion and washdown environments.
A defining feature of the MIC series is the adjustable air cushion at both ends. By turning a needle valve, you tune the end-of-stroke deceleration to absorb shock, protecting your payload and cutting noise compared to a fixed bumper. This specific configuration includes a piston magnet for position sensing and a CA rear pivot cover. 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.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X85SCA Is Used
Package Diverting
Uses the 157 N push force to deflect light cartons at speed, while the adjustable cushion prevents jarring stops that could knock goods over.
Film Sealing Head
Drives a sealing jaw with an 8 kg vertical lift capacity, relying on the needle-set deceleration to protect the heat seal bar from impact wear.
Small Part Ejection
Pushes machined components out of a fixture, using the CA rear pivot to accommodate slight angular misalignment during the ejection arc.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X85SCA the Right Cylinder?
When sizing this 85 mm stroke unit, consider the adjacent bores in the range. Stepping down to the Ø16 bore drops the 0.5 MPa push force to 100.5 N, while moving up to the Ø25 bore increases it to 245.3 N. Choose this Ø20 model for moderate thrust tasks where cycle speed is high enough that the adjustable needle cushions earn their keep by preventing harsh end-stop impacts. The CA back cover provides a rear pivot point for clevis mounting.
Note that the air cushion only decelerates the piston near the stroke end; it does not function as a brake. If your application must hold a load vertically during air loss or valve centering, the piston will drift, so you should add an external rod lock or pilot-operated check valve. The built-in magnet (-S) supports CMSG, DMSG, and EMSG switches for precise end-position detection.
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 MIC20X85SCA FAQ
This Ø20 mm bore cylinder features a 1/8 inch port and an Ø8 mm rod. It generates 157 N push and 131.9 N pull at 0.5 MPa, increasing to 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, the -S suffix denotes a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches. The adjustable air cushion at both ends uses a needle valve to restrict exhaust flow, decelerating the piston smoothly at stroke end to reduce shock and noise.
