Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SCMLB
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SCMLB is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 100mm 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 MI20X100SCMLB
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust 100 mm stroke tasks. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The built-in piston magnet (-S) directly supports CMSG, DMSG and EMSG reed or electronic switches for position sensing.
For practical sizing, plan for about 94 N of real work at 0.5 MPa, which safely lifts an 8 kg vertical load with a 2:1 margin. The ISO 6432 mounting interface drops into standard mini-cylinder brackets and clevises, simplifying spares. Fixed TPU bumper pads decelerate the stroke end without offering adjustable cushioning, while the round CM back cover and included LB foot bracket provide stable base mounting.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SCMLB Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line, using the 157 N push force to deflect moderate-weight cartons reliably at 0.5 MPa.
Textile Loom Tensioner
Positions a yarn tensioning roller in a humid production environment, leveraging the stainless steel barrel to resist mild corrosion.
Bin Lid Lifter
Raises and lowers heavy access hatches on material bins, easily handling an 8 kg lid vertically with a safe 2:1 lifting margin.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SCMLB the Right Cylinder?
When sizing this 100 mm stroke model, compare it against its neighbours: the Ø16 bore yields 100.5 N push at 0.5 MPa, whereas the Ø25 bore steps up to 245.3 N. This Ø20 provides a solid middle ground with 131.9 N of pull force at 0.5 MPa. The included LB foot bracket and CM round rear cover suit fixed-frame installations, and the -S magnet enables CMSG, DMSG or EMSG sensors. If your mechanism requires variable air cushioning for high-speed cycles, consider the MIC variant instead of this fixed-bumper build.
At 100 mm of travel, mind the rod-bending side loads by guiding the payload externally. Remember that a standard cylinder drifts when air is lost or the valve centres; the TPU pads only soften the impact at stroke end and never act as a brake. To suspend a load safely mid-stroke, fit an external rod lock or a pilot-operated check valve.
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 MI20X100SCMLB FAQ
This Ø20 mm bore cylinder features a 1/8" 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 force of 32 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG switches. The cylinder uses fixed TPU bumper pads that decelerate the piston at stroke ends; it does not have adjustable air cushioning, which is found on the MIC variant.
