About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCALB
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust linear motion tasks. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Riveted construction keeps the body compact, while fixed TPU bumper pads absorb stroke-end impacts.
Because the 157 N rating is theoretical, plan for a safe working load of about 94 N at 0.5 MPa. This equates to lifting an 8 kg part vertically with a 2:1 safety margin. The built-in piston magnet supports CMSG, DMSG, and EMSG switches for position sensing. Furthermore, its ISO 6432 mounting dimensions mean it drops directly into standard mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCALB Is Used
Package Diverting Gate
Actuates a routing flap on a packaging conveyor, using the 94 N safe working load to push cardboard cartons onto secondary lanes without stalling.
Vertical Parts Lift
Raises lightweight plastic totes in a pick-and-place station, safely lifting up to 8 kg loads thanks to the 2:1 safety margin at 0.5 MPa.
Washdown Sensor Bracket
Indexes a testing probe into position over a food processing line, relying on the stainless steel construction to withstand humid, rinsed environments.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCALB the Right Cylinder?
When sizing this unit, compare it to neighbouring bores: a Ø16 mm cylinder yields 100.5 N push at 0.5 MPa, whereas a Ø25 mm unit provides 245.3 N. This model includes an LB foot mount for base fixation and a CA rear pivot cover for clevis attachments. The 50 mm stroke is well within the 500 mm maximum, keeping rod bending stress minimal. If your application requires position feedback, the included -S magnet is fully compatible with CMSG, DMSG, and EMSG sensors.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered. The TPU bumpers only decelerate the piston near the stroke end; they do not function as a braking mechanism. To suspend a load safely during an air loss event, integrate an external rod lock or a pilot-operated check valve into your pneumatic 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 MI20X50SCALB FAQ
This Ø20 mm bore cylinder features a 1/8" 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 piston will drift if air is lost; the fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. Use a pilot check valve for holding. It includes an LB foot mount, a CA pivot rear cover, and uses ISO 6432 mounting dimensions for standard brackets.
