Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225R is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 225mm 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 MI20X225R
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 225 mm stroke with ease. The Ø20 mm bore uses a 1/8 inch 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. Fixed TPU bumper pads absorb the impact at stroke end, while the compact riveted body keeps the assembly light.
Because it conforms to ISO 6432 mounting dimensions, this unit drops directly into standard mini-cylinder brackets and clevises. Plan for a safe working load of about 94 N, which lets you lift roughly 8 kg vertically with a 2:1 safety margin. The R back cover features an axial-in port orientation to simplify plumbing in tight spaces. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without upgrading to an -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225R Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 157 N push force to redirect cartons at 0.5 MPa without overstressing the assembly.
Vertical Parts Lift
Raises lightweight plastic totes 225 mm between conveyor tiers, safely lifting components weighing up to 8 kg with a 2:1 safety margin.
Lab Sample Ejection
Ejects processed specimen trays from a testing machine, where the stainless build tolerates frequent chemical wipe-downs and mild washdown exposure.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225R the Right Cylinder?
When sizing this 225 mm stroke model, compare it against its neighbours: the smaller Ø16 bore yields 100.5 N of push at 0.5 MPa, while the larger Ø25 bore provides 245.3 N. If your application demands high-speed cycling with heavier loads, consider the MIC variant for its adjustable air cushion, as the base MI only offers fixed TPU bumpers. For mounting flexibility, you can pair this cylinder with LB foot brackets, FA flanges, SDB pivot blocks or TC trunnions.
A 225 mm stroke generates leverage, so minimize side-loading to prevent rod bending and premature seal wear. Furthermore, a standard double-acting cylinder drifts when air pressure is lost or the valve is centred; the bumper pads only decelerate the end of travel and act as neither a lock nor a brake. To suspend a load safely during an air failure, integrate an external rod lock or a pilot-operated check valve into your 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 MI20X225R FAQ
This Ø20 mm bore cylinder features a 1/8 inch 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.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must select an -S variant (such as MI20X225R-S) to enable magnetic sensing. The unit uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
