The SP016044 slip ring is manufactured using advanced integrated casting technology that ensures concentricity between the bearing and ring groove within 0.01 mm. Precision machining and mirror-grade contact surface finishing significantly improve rotational stability and electrical reliability. It is widely applied in navigation platforms, radar scanning systems, and high-precision measuring instruments.

Outline Drawing

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.
ü The slip ring adopts an integral stainless steel metal structure, which is suitable for extremely harsh environments.
