About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250SCMLB
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 operates on a 1/8" port, while the integrated piston magnet enables position sensing with CMSG, DMSG, or EMSG switches. Its riveted stainless barrel and rod shrug off mild corrosion, giving it a distinct lifespan advantage over painted alternatives in damp or washdown settings.
Designed around ISO 6432 mounting dimensions, the unit drops directly into standard mini-cylinder brackets and clevises. Fixed TPU bumper pads absorb stroke-end impact to protect the mechanism. For practical sizing, plan for a safe working load of roughly 94 N, which means it lifts about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250SCMLB Is Used
Package Diverter Gate
Actuates a routing flap on a packaging conveyor, using the 157 N push force to redirect medium-weight cartons efficiently.
Vertical Parts Lift
Raises lightweight plastic totes 250 mm between conveyor tiers, safely lifting loads up to 8 kg with a proper safety margin.
Damp Environment Stopper
Functions as a pneumatic end-stop on a food processing line, where the stainless steel barrel resists daily washdown moisture.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250SCMLB the Right Cylinder?
When sizing this 250 mm stroke model, compare it against neighbouring bores: the smaller Ø16 generates 100.5 N of push at 0.5 MPa, while the larger Ø25 provides 245.3 N. This Ø20 strikes a middle ground, but its 250 mm stroke demands attention to side loading—ensure the load is guided to prevent rod bending over that extension distance.
This configuration includes an LB foot mount for base securing and a CM round rear cover. Because it features the -S magnet, you can easily attach reed or electronic sensors. Remember that venting the air causes the piston to drift; if your application must hold a load vertically during a pressure loss, install an external pilot check valve or rod lock.
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 MI20X250SCMLB FAQ
This Ø20 mm bore cylinder features 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 force of 32 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the stroke end and do not act as a brake; the piston will drift if air pressure is lost, requiring an external rod lock for holding. This SKU includes an LB foot mount, a CM round rear cover, and an internal magnet (-S) for CMSG, DMSG, or EMSG sensors.
