About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X140SCASDB
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust actuation tasks. The Ø20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted-steel or aluminium minis in damp, food, or outdoor environments. Riveted construction keeps the body compact, while fixed TPU bumper pads absorb the impact at stroke end.
Because the 157 N rating is theoretical, plan for a safe working load of about 94 N at 0.5 MPa. For vertical lifts, this translates to raising roughly 8 kg with a 2:1 safety margin. The built-in -S piston magnet supports CMSG, DMSG, and EMSG switches for position sensing. Conforming to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X140SCASDB Is Used
Package Diverter Gate
Pivots a sorting flap on a packaging line using the SDB block, relying on the 157 N push force to redirect heavy cartons reliably.
Textile Loom Tensioner
Uses the CA clevis mount to maintain proper thread tension in damp manufacturing environments, leveraging the stainless steel rod for corrosion resistance.
Pallet Stacking Pusher
Extends 140 mm to push lightweight components into a stacking fixture, safely lifting parts under the 8 kg vertical threshold.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X140SCASDB the Right Cylinder?
When sizing this actuator, compare its 157 N push force at 0.5 MPa against adjacent bores: the Ø16 generates 100.5 N, while the Ø25 provides 245.3 N. This model includes a CA rear pivot cover and an SDB pivot-block accessory, making it ideal for applications requiring angular alignment. The 140 mm stroke is well within the 500 mm maximum, but at this length you should watch for side loads and rod bending to prevent premature seal wear.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and do not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. Position detection is enabled by the internal magnet, allowing seamless integration of CMSG, DMSG, or EMSG sensors.
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 MI20X140SCASDB FAQ
This Ø20 mm bore cylinder features a 1/8 inch port and an M8x1.25 male rod thread. 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 force of 32 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the piston at stroke end and do not function as a lock; the cylinder will drift if air is lost, requiring an external rod lock for holding. The included -S magnet allows the use of CMSG, DMSG, and EMSG switches for position detection.
