About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X85SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles demanding 85 mm stroke tasks. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its riveted round body shrugs off mild corrosion, outperforming painted alternatives in washdown zones. The built-in magnet (-S) directly supports CMSG, DMSG and EMSG reed or electronic switches.
Because the 157 N rating is theoretical, plan for a real working load of roughly 94 N at 0.5 MPa. That translates to safely lifting an 8 kg part vertically with a 2:1 margin. The rear CA pivot cover complements standard ISO 6432 mounting dimensions, making bracket alignment straightforward. Fixed TPU bumper pads absorb end-of-stroke impacts without needing adjustment.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X85SCA Is Used
Package Diverter Arm
Pivots a guide rail via the CA clevis to sort 8 kg cartons on a washdown-ready stainless-steel assembly line.
Textile Loom Tensioner
Extends 85 mm to position a yarn tensioning roller, using the 94 N safe working load to maintain consistent fabric feed.
Bottle Cap Press
Cycles double-acting at high speed to press plastic caps, relying on fixed TPU pads to soften the end impact.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X85SCA the Right Cylinder?
When sizing this 85 mm stroke unit, verify your actual load against the 131.9 N pull force at 0.5 MPa. If you need less power, the Ø16 bore provides 100.5 N push; stepping up to the Ø25 bore yields 245.3 N. Remember that venting air or centering the valve causes the piston to drift, as the TPU pads only decelerate travel rather than locking the rod. For suspended loads, install an external pilot check valve.
The included -S magnet enables position sensing with CMSG, DMSG or EMSG switches. The CA rear clevis is perfect for pivoting loads, while the 1/8" port matches standard 20 mm mini-cylinder fittings. An 85 mm stroke on an Ø8 mm rod handles normal compression well, but guard against side loads to prevent rod bending.
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 MI16-20 Stainless Steel Mini Cylinder MI20X85SCA FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. This Ø20 mm bore uses a 1/8" air port and an M8x1.25 male rod thread.
No, the piston drifts if air is lost or the valve is centered; the fixed TPU pads only decelerate the stroke end and do not act as a brake. Use a pilot check valve for holding. The -S magnet allows CMSG, DMSG and EMSG switches for position sensing.
