About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X325SCALB
Delivering 157 N of push force at 0.5 MPa, the AirTAC MI20X325SCALB is a double-acting round-body mini cylinder built for demanding automation. Its stainless-steel barrel and Ø8 mm rod shrug off mild corrosion, making it far superior to painted alternatives in damp or washdown settings. The 325 mm stroke falls well within the 500 mm maximum for this bore, while the 1/8" port ensures rapid cycling across the 30-800 mm/s speed range.
This SKU includes a piston magnet for CMSG, DMSG or EMSG position sensing. It features a CA rear pivot cover and an LB foot mounting accessory. Thanks to its ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets. For practical sizing, plan for about 94 N of real work at 0.5 MPa, which means it can safely lift an 8 kg part vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X325SCALB Is Used
Package Diverters
Pushes medium cartons off a main conveyor belt using the 157 N thrust and 325 mm reach, with the LB foot keeping the body rigid during rapid cycles.
Vertical Part Lifts
Raises lightweight 8 kg bins between tiers in a storage rack, relying on the stainless rod to resist humidity in unheated warehouses.
Guard Door Actuators
Opens and closes interlocked machine safety doors, using the CA pivot to accommodate slight angular misalignment during the 325 mm travel.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X325SCALB the Right Cylinder?
When sizing this 20 mm bore, the smaller MI16 offers 100.5 N of push at 0.5 MPa, while the larger MI25 steps up to 245.3 N. This model sits perfectly in the middle for medium-duty tasks. The included LB foot bracket and CA clevis cover provide flexible mounting options for your frame.
Note that fixed TPU bumper pads only soften the stroke-end impact; they do not act as a lock. If air pressure drops, the piston will drift, so install an external rod lock or pilot check valve to suspend loads safely. The 325 mm stroke demands careful alignment to prevent rod bending under side loads.
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 MI20X325SCALB FAQ
This 20 mm bore cylinder uses a 1/8" air 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.
Yes, the built-in -S magnet allows you to mount CMSG, DMSG or EMSG switches directly to the body. For impact absorption, it relies on fixed TPU bumper pads that decelerate the piston at the stroke ends; it does not feature adjustable air cushioning.
