About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X500SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 500 mm stroke with ease. The riveted barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. Its 1/8" port and M8x1.25 male rod thread ensure straightforward integration.
Equipped with fixed TPU bumper pads to absorb end-of-stroke impact, it operates at speeds of 30-800 mm/s. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing. For real-world tasks, plan for roughly 94 N of usable work at 0.5 MPa, which means it can lift about 8 kg vertically with a safe 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X500SCM Is Used
Long-Reach Diverting
Pushes packages across a 500 mm conveyor lane using the full stroke, relying on the 157 N thrust to overcome friction.
Vertical Parts Lift
Elevates lightweight bins between machine tiers, safely moving roughly 8 kg loads thanks to the 2:1 safety margin.
Film Roll Feed
Unwinds packaging material in damp facilities where the stainless steel barrel prevents mild corrosion.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X500SCM the Right Cylinder?
This Ø20 bore sits between the MI16 (100.5 N push at 0.5 MPa) and the MI25 (245.3 N push at 0.5 MPa), giving you a clear upgrade path if your air pressure fluctuates. The CM round end cover provides a clean rear profile, while the ISO 6432 mounting interface lets you drop the unit straight into standard mini-cylinder brackets and clevises.
At 500 mm, this stroke pushes the maximum standard limit for this bore, so verify side-loading to avoid rod bending. Because a standard cylinder drifts when air is lost or a valve is centered, add an external rod lock or pilot check valve if you need to suspend a load safely.
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 MI20X500SCM FAQ
This double-acting cylinder has a 1/8" port and generates 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, the -S suffix denotes a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The CM designation indicates a round rear cover, and the body uses standard ISO 6432 mounting dimensions for easy bracket fitting.
