Airtac MI16-20 Stainless Steel Mini Cylinder MI16X35U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X35U is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 35mm 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 MI16X35U
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation with ease. The 16 mm bore uses a 1/8" port and a 6 mm piston rod, while the rolled riveted body shrugs off mild corrosion better than painted alternatives. Fixed TPU pads absorb end-of-stroke impact. Plan for roughly 60 N of actual work at 0.5 MPa, which translates to lifting about 5.1 kg vertically with a safe 2:1 margin.
The U suffix equips the rear cover with a 90-degree mounting orientation for tight spatial constraints. Because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG sensors. The 35 mm stroke operates at 30-800 mm/s, conforming to ISO 6432 mounting dimensions for straightforward bracket integration.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X35U Is Used
Component Ejection
Pushes small moulded plastic parts out of an injection press using the 100.5 N output, leveraging the 90-degree rear cover to fit alongside the mould base.
Package Deflection
Actuates a routing gate on a packaging line to sort small cardboard cartons, benefiting from the stainless construction during periodic washdowns.
Clamp Actuation
Secures thin aluminium brackets in a CNC machining fixture, using the 35 mm stroke to clear the workpiece rapidly before the next cycle.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X35U the Right Cylinder?
When sizing this 16 mm bore, compare it against its neighbours: a 12 mm bore yields 56.5 N of push at 0.5 MPa, whereas stepping up to a 20 mm bore provides 157.0 N. The 35 mm stroke is well within the 500 mm maximum, keeping rod bending stress minimal. Remember that venting the air supply causes the piston to drift, as the fixed bumpers only decelerate the stroke end rather than locking the load; add an external pilot check valve if you need to hold position vertically.
This non-magnetic version precludes switch integration, so choose an -S variant if your control system requires CMSG, DMSG or EMSG feedback. Alongside the standard U rear cover, the series supports LB foot, FA flange, SDB pivot and TC trunnion brackets to fit various machine frames.
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 MI16X35U FAQ
At 0.5 MPa it provides 100.5 N push and 86.4 N pull. At 0.7 MPa it provides 140.7 N push and 120.9 N pull. The theoretical maximum force is 20.5 kgf at 1.0 MPa. The air port size is 1/8".
No, this SKU lacks the internal magnet required for CMSG, DMSG or EMSG switches; you would need the -S variant for sensing. The U suffix denotes a 90-degree rear cover, allowing the cylinder body to sit perpendicular to the mounting plane for compact installations.
