About the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI16X75SCA
This 16 bore round-body mini cylinder delivers 100.5 N of push force at 0.5 MPa, making it a compact workhorse for light automation tasks. The B52- prefix marks AirTAC's copper-free construction, a build for lines where copper and copper alloys are not permitted, such as ammonia systems or certain battery and electronics plants.
The stainless-steel barrel and rod resist mild corrosion and washdown, a genuine advantage over painted-steel or aluminium minis in damp or food-adjacent spots. Since this unit carries the -S magnet, you can fit CMSG, DMSG, or EMSG switches for position sensing. For real-world work, plan on roughly 60 N of safe load at 0.5 MPa-about 60% of the rated figure-which translates to lifting about 5.1 kg vertically with a 2:1 safety margin.

Where the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI16X75SCA Is Used
Small Parts Ejection
Use the 100.5 N push force to eject small plastic components from a die-cast or injection moulding machine. The 75 mm stroke clears the part from the cavity, and the stainless rod resists the occasional splash of mould release agent.
Ammonia System Valve Actuation
In an ammonia-based refrigeration or chemical plant, the copper-free B52- build is the right call where copper alloys are prohibited. This cylinder can actuate a small 2-way valve, with the 86.4 N pull force at 0.5 MPa handling the return stroke.
Carton Flap Folder
Mount this cylinder on a packaging line to fold and hold a carton flap during sealing. The 75 mm stroke is enough for standard carton depths, and the TPU bumpers soften the end of each cycle, reducing noise in a busy packing area.
Is the Airtac B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI16X75SCA the Right Cylinder?
At 75 mm stroke, this unit sits between the smaller 12 bore (56.5 N push) and the larger 20 bore (157.0 N push) at 0.5 MPa. If you need more force, step up to the 20; if space is tighter, the 12 will fit smaller envelopes. The CA back cover provides a pivot/clevis mounting point, and the 1/8" port suits standard miniature fittings.
Remember that a plain cylinder does not hold its load if air pressure is lost or the valve centres-the piston will drift. The fixed TPU bumper pads only decelerate the stroke end; they are not a lock or brake. For a held load, use an external rod lock or a pilot-operated check valve. With a 75 mm stroke, keep side loads low to protect the rod and extend seal life.
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 B52-MI Copper-Free Stainless Steel Mini Cylinder B52-MI16X75SCA FAQ
At 0.5 MPa, the push force is 100.5 N and the pull force is 86.4 N. At 0.7 MPa, push rises to 140.7 N and pull to 120.9 N. The theoretical maximum is 20.5 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa. The rod is 6 mm with an M6x1.0 male thread, and the port is 1/8".
The B52- prefix marks AirTAC's copper-free (copper-prohibited) build of the MI16X75SCA. It is designed for lines where copper and copper alloys are not permitted, such as ammonia systems or some battery and electronics plants. The exact material substitutions should be confirmed with us. This unit has the -S magnet, so it is compatible with CMSG, DMSG, or EMSG switches for position sensing.
