Technical advantages:
ü Gold gold contact has high conductivity, good thermal conductivity,
low temperature coefficient of resistance (with characteristics
such as resistance to sulfurization, oxidation, and corrosive
gases), and good hardness and wear resistance (with good resistance
to welding, arc corrosion, and burns).
ü Integrated casting process: Ensure the concentricity between the
ring groove and the bearing is ≤ 0.01mm.
ü Mirror processing technology: Ensure that the smoothness of the
slip ring contact surface can reach Ra0.02, making the contact more
reliable.
ü Precision component manufacturing process: dimensional
tolerance<0.01mm, high precision, and more stable contact.
ü The design and debugging process of the electric brush, which is
close to zero pressure, has extended the life of the slip ring by
1/3.
ü Small in size and compact in structure, it can meet the space
constraints of users.
