About the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI16X300SU
The B52-MI16X300SU delivers 100.5 N of push force at 0.5 MPa from its 16 mm bore, with a matching pull of 86.4 N. This double-acting, round-body mini cylinder uses a stainless-steel barrel and rod, offering mild corrosion resistance for damp or washdown environments. The B52- prefix marks AirTAC's copper-free build, making it suitable for lines where copper and copper alloys are not permitted, such as ammonia systems or certain battery and electronics plants.
Its riveted construction keeps the cylinder compact and lightweight, while fixed TPU bumper pads soften the stroke end impact. The built-in -S magnet enables use with CMSG, DMSG, or EMSG switches for position sensing. With a 300 mm stroke, this cylinder fits within the standard 500 mm maximum for the 16 mm bore and uses a 1/8" port. For a typical application, plan for a safe working load of about 60 N at 0.5 MPa, which allows a margin for dynamic forces and friction.

Where the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI16X300SU Is Used
Small Parts Ejector
Use the 100.5 N push force at 0.5 MPa to eject small stamped metal parts from a die or fixture. The stainless rod resists the minor corrosion from cutting fluids, and the 300 mm stroke clears the part completely.
Ammonia System Valve Actuator
In a chemical plant's ammonia handling line, this copper-free B52 cylinder actuates a small diversion valve. Its stainless-steel construction withstands mild corrosive exposure, and the copper-free build prevents contamination in the process stream.
Carton Indexing Stop
On a packaging conveyor, this cylinder with its 300 mm stroke can raise a stop to index cartons. The 86.4 N retract force at 0.5 MPa is sufficient to lower the stop against the carton's weight, and the TPU bumpers absorb the impact of repeated cycling.
Is the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI16X300SU the Right Cylinder?
When sizing, consider the 12 mm bore MI12X300, which provides 56.5 N push at 0.5 MPa, if your load is lighter. Conversely, the 20 mm bore MI20X300 offers 157.0 N push at 0.5 MPa for a more substantial force increase. This B52-MI16X300SU has a 300 mm stroke, which is within the standard range, but a long stroke can increase side-loading on the rod; use a guide or support if the load is off-center. The 90-degree back cover (U style) directs the rear port perpendicular to the cylinder axis, which can simplify plumbing in tight spaces. Since this model has the -S magnet, you can fit CMSG, DMSG, or EMSG switches. Note that a standard MI cylinder does not hold its position when air pressure is lost; for a held load, you would need an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure

The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa. The speed range is 30-800 mm/s, and the temperature range is -20 to +70 degrees C.
The B52- prefix designates AirTAC's copper-free (copper-prohibited) build of the MI16X300SU. This means the cylinder is manufactured without copper or copper alloys in its construction, making it suitable for applications where these materials are not permitted, such as in ammonia systems or certain battery and electronics plants. The exact material substitutions are not specified in our data; please confirm the specific details with us to ensure it meets your requirements. The cylinder retains its stainless-steel barrel and rod, and the -S magnet for sensors.
