About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SR
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless steel round-body mini cylinder handles a 100 mm stroke with a 1/8" port and an M8x1.25 male rod thread. The Ø20 mm bore conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for straightforward design integration. An integrated piston magnet is included, allowing you to mount CMSG, DMSG, or EMSG reed and electronic switches for end-of-stroke position sensing.
The riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at the stroke extremes without offering adjustable cushioning. For practical sizing, plan for a safe working load of about 94 N, which means it can lift a roughly 8 kg part vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SR Is Used
Package Diverter Gate
Actuates a routing flap on a packaging conveyor, using the 8 kg vertical lift capacity to swing the guide and redirect light cardboard cartons.
Textile Loom Tensioner
Maintains consistent yarn tension in a damp textile facility, leveraging the stainless steel construction to resist humidity and mild washdown spray.
Label Applicator Pusher
Extends 100 mm to press adhesive labels onto product cases, relying on the CMSG sensor magnet to confirm the stroke end for the control system.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SR the Right Cylinder?
When sizing this 100 mm stroke unit, the neighboring Ø16 bore provides 100.5 N of push at 0.5 MPa, while stepping up to the Ø25 bore yields 245.3 N, giving you clear boundaries if your force requirements shift. The R back cover style supplies a rear axial-in port orientation, which helps streamline hose routing in tight machinery. Because the stroke is a moderate 100 mm, keep an eye on side loading to prevent rod bending and premature seal wear.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centered; the TPU pads only decelerate the end of stroke and do not function as a locking brake. To suspend a load safely during an air loss event, incorporate an external pilot-operated check valve or a dedicated rod lock.
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 MI20X100SR FAQ
This double-acting cylinder has 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, it uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion. Additionally, it will drift if air is lost or the valve is centered; use an external rod lock or pilot check valve to hold a load securely.
