About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150CAFA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 150 mm stroke with a rugged riveted construction. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Built to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises.
Fixed TPU bumper pads absorb impact at the stroke ends, though they decelerate rather than act as an adjustable cushion. For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which translates to lifting about 8 kg vertically with a 2:1 safety margin. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150CAFA Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 157 N push force to redirect medium-weight cartons off the main belt.
Textile Loom Tensioner
Adjusts the tension arm on a weaving machine, benefiting from the stainless build to resist humid manufacturing environments.
Pallet Labelling Arm
Extends 150 mm to press an applicator head against inbound pallets, utilizing the CA clevis for smooth pivot alignment.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150CAFA the Right Cylinder?
When sizing this 150 mm stroke unit, the neighbouring Ø16 bore offers 100.5 N of push at 0.5 MPa, while stepping up to the Ø25 yields 245.3 N. This model includes a CA rear pivot cover and an FA flange accessory, providing flexible mounting options for your mechanical setup. If your mechanism relies on staying put during air loss or valve centring, remember this standard cylinder will drift; the bumpers only soften the end of travel, so an external rod lock or pilot check valve is required to hold a load.
With a 150 mm extension, carefully manage side loading to avoid rod bending. The unit operates smoothly between 30-800 mm/s, and because there is no internal magnet, you must choose the -S variant if your control system requires sensing.
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 MI20X150CAFA FAQ
This Ø20 mm bore cylinder features a 1/8" port and an M8x1.25 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, this specific SKU does not include the -S magnet, so it cannot support CMSG, DMSG or EMSG switches. You would need the -S variant for sensing. It uses fixed TPU bumper pads for deceleration and conforms to ISO 6432 mounting dimensions.
