SP013028 High Speed Slip Ring Mini Rotary Joint Ring

Product Overview

SP013028 series products are tailored for small space slip rings required by rotary systems, meeting the full performance conditions of launch, storage, and operation. The special manufacturing process ensures superior slip ring performance retention during long-term storage.

Technical Parameters

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.
