Airtac MI16-20 Stainless Steel Mini Cylinder MI20X210SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X210SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 210mm 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 MI20X210SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 210 mm stroke with a built-in magnet and CA pivot clevis. 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-steel alternatives in damp or washdown environments. Riveted construction keeps the body compact, while fixed TPU bumper pads absorb impact at the stroke ends.
Plan for roughly 94 N of actual work at 0.5 MPa, which safely lifts an 8 kg part vertically with a 2:1 margin. The integrated piston magnet allows direct mounting of CMSG, DMSG or EMSG sensors for position detection. Because the rear features a CA clevis, the cylinder pivots smoothly during operation to accommodate lateral movement.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X210SCA Is Used
Package Diverting Gate
Pivots a sorting flap on a packaging line using the CA clevis, applying 157 N of push to redirect medium-weight cartons at 0.5 MPa.
Film Roll Tensioning
Maintains consistent tension on a wrapping machine, using the 210 mm stroke to feed material while the stainless rod resists humid conditions.
Component Ejection
Pushes machined aluminium parts out of a CNC fixture, lifting an 8 kg component vertically with a safe 2:1 working margin.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X210SCA the Right Cylinder?
When sizing this 210 mm stroke unit, 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 you need more power. This Ø20 model sits comfortably in the middle, providing 131.9 N of pull force at 0.5 MPa. At 210 mm, the stroke is well within the 500 mm maximum, but the extended Ø8 mm rod requires careful alignment to prevent side-loading and premature seal wear.
The CA rear clevis mount pairs with standard ISO 6432 mini-cylinder brackets, simplifying your design and spares inventory. Remember that a standard cylinder drifts when air is removed or the valve is centred; the TPU bumpers only decelerate the stroke end and will not lock the load. Use an external rod lock or pilot check valve if you must hold position vertically.
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 MI20X210SCA FAQ
This double-acting cylinder uses 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 of 32 kgf at 1.0 MPa.
No, it features fixed TPU bumper pads that decelerate the stroke end rather than an adjustable air cushion. It also does not hold position when air is lost; you need an external rod lock or pilot check valve for load holding. The -S magnet supports CMSG, DMSG and EMSG sensors.
