About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X500CM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles long 500 mm reach operations with ease. The Ø20 mm bore operates on a 1/8" port and features an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a genuine edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the piston without the complexity of adjustable cushioning.
Because it lacks a -S suffix, this specific SKU cannot accept position sensors; you must specify the -S variant to use CMSG, DMSG or EMSG switches. For practical sizing, plan for roughly 94 N of usable work at 0.5 MPa, which equates to lifting about 8 kg vertically with a safe 2:1 margin. The CM round end cover completes the rear assembly, keeping the body compact despite the half-metre stroke.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X500CM Is Used
Film Roll Diverter
Pushes packaging film rolls sideways onto adjacent conveyor lanes using the 500 mm stroke, relying on the stainless body to endure humid converting rooms.
Textile Beam Indexer
Extends fully to shift heavy textile beams between processing stations, using the 157 N thrust to overcome initial sliding friction.
Carton Sorting Gate
Actuates a routing gate for cardboard cartons on a packing line, where the fixed TPU bumpers quietly absorb 800 mm/s end-of-stroke impacts.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X500CM the Right Cylinder?
When sizing this 500 mm stroke unit, verify your guidance because a long 8 mm rod is vulnerable to bending under side loads. If you need less push, the Ø16 bore provides 100.5 N at 0.5 MPa; stepping up to the Ø25 bore yields 245.3 N. This model uses standard ISO 6432 mounting dimensions, so it drops directly into standard mini-cylinder brackets and clevises. Remember that venting or centring the valve causes the piston to drift downward, as the TPU pads only soften the end of travel rather than locking the load. Use a pilot-operated check valve if you must hold a vertical weight mid-stroke.
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 MI20X500CM FAQ
This Ø20 mm bore cylinder uses a 1/8" port. 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.
No, this SKU lacks the internal magnet so it cannot accept CMSG, DMSG or EMSG switches. You must select the -S variant for position sensing. It uses standard ISO 6432 mounting dimensions and a CM round end cover.
