Technical advantages
- Gold-gold contact, high conductivity, good thermal conductivity, small temperature coefficient of resistance (resistance to vulcanization, oxidation, corrosive gases, etc.), a certain hardness, good wear resistance (good fusion welding resistance, resistance to arc corrosion and burns).
- Integrated pouring process: ensure that the concentricity of the ring groove and the bearing is ≤ 0.01 mm.
- Mirror processing technology: ensure that the contact surface finish of the slip ring can reach Ra0.02, and the contact is more reliable.
- Precision component manufacturing process: dimensional tolerances<0.01mm, High precision, more stable contact.
- The service life of the slip ring is prolonged by 1/3 due to the brush design and debugging process close to zero pressure.
- Small size, compact structure, can meet the user's space constraints.
- The slip ring is made of integral stainless steel metal structure, which is suitable for extremely harsh environment.
