Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 20mm 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 MI20X20SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The 20 mm stroke and CA pivot clevis back cover make it ideal for tight rotary actuation setups. Its 1/8" port feeds the Ø8 mm piston rod, yielding a theoretical maximum output of 32 kgf at 1.0 MPa.
The stainless barrel and rod resist mild corrosion, outperforming painted alternatives in damp or washdown environments. Fixed TPU bumper pads absorb end-of-stroke impact without adding bulk. Because the bore is Ø20, it conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets. Plan for roughly 94 N of actual work at 0.5 MPa, which means it can safely lift an 8 kg part vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20SCA Is Used
Package Diverter Arm
Uses the 20 mm stroke and CA clevis to rapidly push small cardboard cartons off a sorting line, relying on the 157 N push force to overcome box friction.
Small Parts Clamp
Secures lightweight aluminum brackets during a CNC drilling operation, where the 8 kg vertical lift capacity ensures the part stays firmly seated against the fixture.
Film Seal Press
Cycles the heated jaw on a vertical form-fill-seal machine, using the stainless construction to withstand occasional washdown and product spillage.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20SCA the Right Cylinder?
When sizing this actuator, the 157 N push at 0.5 MPa sits comfortably between the smaller Ø16 bore (100.5 N) and the larger Ø25 bore (245.3 N). Choose the Ø20 to efficiently handle loads that overwhelm a 16 mm bore but do not require the bulk of a 25 mm unit. The integrated -S magnet allows direct mounting of CMSG, DMSG, or EMSG sensors for position detection.
The CA rear clevis provides a pivot point for angular movement, while the fixed TPU bumpers decelerate the stroke end without adjustable cushioning. Remember that a standard double-acting cylinder drifts if air pressure is lost or the valve is centered; the bumpers will not lock the load. Use an external pilot check valve or rod lock if you need strict position holding.
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 MI20X20SCA 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 compatible with CMSG, DMSG, and EMSG switches. The CA back cover provides a pivot clevis pin mount, and the body uses ISO 6432 dimensions for standard bracket interchange.
