Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160SR
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160SR is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 160mm 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 MI16-20 Stainless Steel Mini Cylinder MI20X160SR
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 160 mm stroke with an M8x1.25 rod. The Ø20 mm bore uses a 1/8 inch air port and conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for easy design integration. A built-in piston magnet (-S) supports CMSG, DMSG, and EMSG switches for position sensing.
The stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Fixed TPU bumper pads decelerate the piston at both stroke ends, while the R back cover provides an axial-in port orientation. Plan for roughly 94 N of actual work at 0.5 MPa, which means it can safely lift about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160SR Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 157 N thrust to push corrugated boxes onto secondary tracks at high cycling speeds.
Lab Sample Ejection
Ejects processed specimen trays from a testing carousel, where the stainless build resists chemical exposure and the 160 mm stroke clears the mechanism.
Bin Lid Lifting
Raises lightweight access hatches on material hoppers, comfortably lifting the roughly 8 kg lid while the ISO 6432 bracket simplifies frame mounting.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160SR the Right Cylinder?
When sizing this 160 mm stroke model, the Ø16 bore offers a smaller footprint with 100.5 N push at 0.5 MPa, while the Ø25 bore steps up to 245.3 N if your load requires more thrust. Because the 160 mm stroke is relatively long for a mini cylinder, ensure proper guiding to prevent rod bending and side-load wear. The -S magnet enables electronic or reed sensors, and the R rear cover dictates your axial port direction.
Remember that a plain double-acting cylinder drifts when air is lost or the valve is centered; the TPU bumpers only soften the end-of-stroke impact and do not function as a brake. To suspend a load safely mid-stroke, incorporate an external pilot-operated check valve or a dedicated rod lock.
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 MI20X160SR FAQ
This Ø20 mm bore cylinder features a 1/8 inch air port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 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, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not act as a lock. You must use an external pilot check valve or rod lock to hold a suspended load.
