About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X115SCM
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation tasks with ease. The Ø16 mm bore uses a 1/8 inch air port and a Ø6 mm piston rod with an M6x1.0 male thread. Its round-body barrel and rod are built from stainless steel to resist mild corrosion and washdowns, offering a real advantage over painted alternatives in damp environments. Fixed TPU bumper pads absorb the impact at stroke ends, decelerating the motion smoothly.
Because the bore conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises for straightforward design integration. The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG position switches. For practical sizing, plan for a safe working load of about 60 N, which means it can vertically lift roughly 5.1 kg with a 2:1 safety margin. The CM round end cover provides a clean rear finish for this 115 mm stroke configuration.

Lab Sample Handling
Lifts approximately 5.1 kg of vertical test-tube racks with a 2:1 safety margin in damp laboratory settings.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X115SCM the Right Cylinder?
When sizing this unit, note that stepping down to a Ø12 bore drops the 0.5 MPa push force to 56.5 N, while moving up to a Ø20 bore increases it to 157.0 N. This 115 mm stroke is well within the 500 mm maximum for the bore, but at extended lengths you should watch for side loads to prevent rod bending. The -S magnet is essential if your control system requires CMSG, DMSG, or EMSG sensors for end-of-stroke confirmation. Keep in mind that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered; the TPU bumpers only soften the end of travel and do not act as a brake. To suspend a load safely during an air loss event, incorporate 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 MI16X115SCM FAQ
This Ø16 mm bore cylinder features a 1/8 inch air port and generates a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa. At 0.7 MPa, the push increases to 140.7 N and the pull to 120.9 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered, as the fixed TPU bumper pads only decelerate the stroke end and do not lock the rod. For vertical loads, you must use an external rod lock or a pilot-operated check valve. The -S magnet allows CMSG, DMSG, and EMSG sensors to track position.
