Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250R is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 250mm 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 MI20X250R
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 250 mm stroke with a 1/8 inch air port. The stainless barrel and rod naturally resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Its riveted construction remains compact, while fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
Because the Ø20 mm body follows ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. For actual moving tasks, plan for around 94 N of real work at 0.5 MPa, which translates to lifting an 8 kg part vertically with a safe 2:1 margin. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without upgrading to the -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250R Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using 157 N of thrust, with the 250 mm stroke clearing the full belt width.
Textile Loom Tensioner
Cycles continuously to maintain fabric tension in humid textile facilities, relying on the stainless rod to resist mild corrosion.
Bin Lid Actuator
Raises and lowers heavy tote lids up to 8 kg, utilizing the rear axial R port to keep pneumatic hoses neatly aligned against the frame.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250R the Right Cylinder?
When sizing this 250 mm stroke unit, verify your load against the 157 N push and 131.9 N pull figures at 0.5 MPa. If you need less force, the Ø16 bore provides 100.5 N push, while stepping up to the Ø25 bore yields 245.3 N. The extended 250 mm rod travel demands careful alignment to prevent side-loading and rod bending over distance. The R back cover supplies a rear axial-in port, optimizing compact inline routing for tight machinery.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve centers, as the TPU bumpers only soften the end-of-stroke impact rather than locking the piston. To suspend a load safely during an air loss event, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MI20X250R FAQ
This 20 mm bore cylinder features a 1/8 inch port and generates 157 N push / 131.9 N pull at 0.5 MPa, 219.8 N push / 184.7 N pull at 0.7 MPa, and a theoretical maximum of 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot support CMSG, DMSG or EMSG switches. You must select the -S variant to enable position sensing. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
