Technical advantages:
ü Slipring's core technology - friction pair technology: gold metal contact technology, ensuring an ultra long service life.
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, axial displacement<0.01mm, high precision, and more stable performance.
ü Advanced brush wire modulation technology: Nearly zero pressure brush design and debugging process, extending 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 Stainless steel structure: sturdy and durable, with strong sealing, suitable for extremely harsh environments.
ü Color code recognition interface: easy to install
