About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X55SCA
Generating 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The Ø16 mm bore uses a 1/8 inch air port and an M6x1.0 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. The riveted construction keeps the body light, while fixed TPU bumper pads absorb impact at the stroke ends.
For practical sizing, plan for about 60 N of real work at 0.5 MPa, which translates to lifting roughly 5.1 kg vertically with a 2:1 safety margin. Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG switches directly for position sensing. The CA back cover provides a rear pivot point for clevis mounting.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X55SCA Is Used
Gate Deflector Arms
Uses the CA pivot clevis to swing a sorting gate on a packaging line, applying 100.5 N to redirect lightweight cartons at 0.5 MPa.
Belt Tensioner Adjustment
Stainless build survives humid food-processing zones while maintaining precise 55 mm stroke adjustments on conveyor belt tracking mechanisms.
Parts Ejector Pusher
CMSG sensors detect the extended position to eject 5 kg tote boxes from a roller conveyor, safely operating within the 60 N working load limit.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X55SCA the Right Cylinder?
When sizing this 16 mm bore, the smaller Ø12 option yields 56.5 N of push at 0.5 MPa, while the larger Ø20 delivers 157.0 N, helping you bracket your force needs. This 55 mm stroke is well within the 500 mm maximum, offering stable performance. Remember that a standard cylinder drifts if air pressure drops or the valve is centred; the bumpers only decelerate the end of travel and do not act as a brake. For suspended loads, add an external rod lock or a pilot check valve.
The built-in magnet supports reed and electronic sensors, and the CA rear clevis suits pivoting linkages. If your application demands high-cycle speed with adjustable end-cushioning, consider the MIC variable-cushion variant instead of this fixed-bumper model.
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 MI16X55SCA FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N. At 0.7 MPa it pushes 140.7 N and pulls 120.9 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa. The air port is 1/8 inch and the male rod thread is M6x1.0.
The stainless-steel barrel and rod provide mild corrosion resistance suitable for outdoor and damp environments. Because this model has the -S magnet, it accepts CMSG, DMSG, and EMSG switches. It uses the ISO 6432 mounting interface for standard mini-cylinder brackets.
