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 High speed, this slip ring can reach a maximum speed of 8000 revolutions per minute (with cooling system).
ü Long lifespan, with a maximum lifespan of up to 100 million revolutions per minute.
