Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50CASDB
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50CASDB is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 50mm 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 MI20X50CASDB
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust linear motion 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, making it superior to painted alternatives in damp or washdown environments. Built with fixed TPU bumper pads to decelerate the stroke end, it operates smoothly across a 30-800 mm/s speed range.
For practical sizing, plan for about 94 N of real work at 0.5 MPa, which safely lifts an 8 kg load vertically with a 2:1 margin. The unit features a CA rear pivot cover and includes an SDB pivot block. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50CASDB Is Used
Package Diverter Arm
Swings a lightweight routing gate on a packaging line, using the CA clevis and SDB block to pivot smoothly while pushing 157 N at 0.5 MPa.
Textile Loom Tensioner
Adjusts yarn tensioner guides in a humid textile facility, where the stainless steel barrel prevents mild corrosion that would degrade standard cylinders.
Bin Lid Actuation
Opens and closes hopper lids on a sorting station, easily lifting an 8 kg lid vertically with a safe 2:1 margin at 0.5 MPa operating pressure.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50CASDB the Right Cylinder?
When sizing this 50 mm stroke actuator, note the Ø16 bore below offers 100.5 N push at 0.5 MPa, while the larger Ø25 bore provides 245.3 N. This model includes the CA clevis back cover and SDB pivot block, but because it lacks the -S suffix, magnetic sensing is not supported. If you need position feedback, specify an -S variant to accept CMSG, DMSG or EMSG switches.
The fixed TPU bumpers only soften end-of-stroke impacts; they do not function as a lock. If air pressure drops or the valve centres, the piston will drift, so fit an external rod lock or pilot-operated check valve to hold a suspended load securely.
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 MI20X50CASDB FAQ
This Ø20 mm bore cylinder features a 1/8" port. 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.
No, this specific SKU lacks the internal magnet, so CMSG, DMSG and EMSG switches cannot be used. You must select an -S variant for position sensing. It uses fixed TPU bumper pads for end deceleration, not an adjustable air cushion.
