About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X155SCA
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 155 mm stroke with a 1/8 inch port and M6x1.0 male rod thread. The stainless barrel and piston rod supply mild corrosion resistance, making it well-suited for damp environments or light washdown areas where painted steel degrades. Built-in fixed TPU bumper pads absorb impact energy at the stroke ends, decelerating the piston smoothly without the complexity of adjustable cushioning. Because the bore is Ø16, it conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for straightforward design integration.
This specific SKU includes a piston magnet (-S) for position sensing with CMSG, DMSG or EMSG switches, and features a CA rear pivot cover for clevis mounting. For practical sizing, plan for a safe working load of about 60 N at 0.5 MPa, which equates to lifting roughly 5.1 kg vertically with a 2:1 safety margin. The 155 mm stroke is well within the 500 mm maximum for this bore, keeping the Ø6 mm rod stable while operating across the 30-800 mm/s speed range.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X155SCA Is Used
Textile Loom Guide
Shifts a yarn guide carriage through a 155 mm cycle, utilising the 100.5 N push force and CA pivot to accommodate slight angular misalignment during high-speed weaving.
Carton Flap Folder
Folds corrugated box flaps prior to sealing, where the stainless steel construction resists adhesive fumes and the safe 60 N working load prevents crushing the cardboard.
Sorting Diverter Arm
Actuates a routing gate on a packaging line, using the -S magnet and DMSG sensor to confirm stroke completion before the next parcel arrives.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X155SCA the Right Cylinder?
When sizing this 16 mm bore, compare it against its neighbours: step down to an Ø12 bore if your task requires less than 56.5 N push at 0.5 MPa, or step up to an Ø20 bore if you need the 157.0 N push force to move heavier fixtures. The CA back cover provides a rear pivot point for angular alignment, ideal for mechanisms that swing through an arc rather than pushing on a perfectly rigid plane. If your mechanism must maintain its vertical position when air pressure drops or the valve is centred, this cylinder will drift; the TPU bumpers only soften the end of travel and act as neither a brake nor a lock. In such cases, specify an external rod lock or a pilot-operated check valve to hold the load securely.
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 MI16X155SCA FAQ
This 16 mm bore cylinder uses a 1/8 inch air port and a Ø6 mm rod with an M6x1.0 male thread. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, and a theoretical maximum of 20.5 kgf at 1.0 MPa.
The stainless-steel barrel and rod offer mild corrosion resistance suitable for outdoor use, and the ISO 6432 mounting dimensions ensure standard bracket fitment. It uses fixed TPU bumper pads for end-of-stroke deceleration, but it does not hold position on air loss; you will need an external rod lock or pilot check valve to prevent drift.
