In today's world where many fields such as mechanical manufacturing, automation equipment, and aerospace are constantly pursuing efficiency and precision, through bore conductive slip rings are playing an increasingly important role as core components for realizing power and signal transmission between rotating parts and fixed parts. It is not only the key to the normal operation of equipment, but also an important part of promoting technological innovation in various industries. Next, let us take a deeper look at this precision device.
Ⅰ. What is a through bore conductive slip ring?
A through bore conductive slip ring is a conductive slip ring with a through hole in the middle. Its unique structural design allows the rotating shaft or other components to pass through the through hole, so as to achieve stable transmission of power, data signals, fluid media, etc. during the rotation of the equipment. It is mainly composed of rotor, stator, brush, housing and other components. The rotor is connected to the equipment component that needs to rotate, and the stator is fixed on the base of the equipment. The electrical connection is formed through the close contact between the brush and the rotor. When the equipment rotates, it can still maintain uninterrupted transmission of power and signals, solving the problem that the traditional connection method cannot achieve continuous transmission in the rotation motion.
Ⅱ. Core technical advantages and specific technical parameters of through bore slip rings
(I) Core technical advantages
Efficient space utilization: The through bore design greatly saves the installation space of the equipment, especially for equipment with limited space and need to integrate multiple functions. For example, in the joints of small drones and industrial robots, through bore conductive slip rings allow the rotating shaft to pass directly through the through hole, avoiding additional space occupation and making the equipment structure more compact.
Multi-function transmission: In addition to being able to stably transmit power and various electrical signals (such as USB, Ethernet, HDMI signals, etc.), some through bore conductive slip rings can also realize the transmission of fluid media such as gas and liquid. In some chemical equipment and food filling machinery, this multi-function transmission feature meets the complex working requirements of the equipment.
High reliability and long life: Using high-quality conductive materials and precision manufacturing processes, through bore conductive slip rings have good wear resistance and low contact resistance. By special treatment of the brush and rotor surface, friction and wear are reduced, thereby extending the service life of the slip ring and reducing the maintenance cost and downtime of the equipment.
(II) Main technical parameters

During the flight of drones, slip rings ensure power and data transmission between the flight control system and rotating propellers, cameras and other components, ensuring the stable flight of drones and high-definition image return.
Energy and power: In wind turbines, through bore conductive slip rings are used to connect the rotating blade hub with the fixed nacelle to realize power transmission from the blades to the generator, as well as bidirectional transmission of control signals. In addition, in solar tracking systems, slip rings ensure the stable transmission of power and control signals during the rotation of solar panels, improving the utilization efficiency of solar energy.
Medical equipment: In medical equipment such as CT scanners and surgical robots, through bore conductive slip rings enable high-speed data and power transmission between the rotating parts of the equipment and the control unit. For example, when a CT scanner is performing a tomographic scan, the slip ring ensures the stable transmission of the X-ray detector signal, providing doctors with clear and accurate image diagnosis basis.
Ⅳ. How to choose high-quality through bore conductive slip rings?
Clear usage requirements: Determine the basic parameters of the required slip rings according to the working environment of the equipment (such as temperature, humidity, dust conditions), transmission requirements (electric power, signal type, transmission rate), speed requirements, and whether fluid media needs to be transmitted. For example, equipment working in a high-temperature environment needs to choose a high-temperature resistant slip ring; when transmitting high-definition video signals, pay attention to the data transmission rate of the slip ring.
Investigate manufacturing processes and materials: Understand the manufacturing process level of the slip ring manufacturer, such as precision machining technology, assembly process, etc. At the same time, pay attention to the quality of conductive materials (such as precious metal alloys), insulating materials and brush materials. High-quality materials are the basis for ensuring the performance and life of the slip ring. For example, using precious metal alloys as conductive materials can reduce contact resistance and improve transmission stability.

Use a dry, soft brush or clean cloth to remove dust, impurities and oil stains on the surface of the slip ring to prevent these substances from affecting the electrical conductivity and normal operation of the slip ring.
Lubrication treatment: For the rotating parts of the slip ring, add appropriate lubricants regularly according to the manufacturer's requirements to reduce friction and wear and extend the service life of the slip ring. Pay attention to the amount and application method of the lubricant to avoid excessive or uneven application that may cause other problems.
(II) Troubleshooting
Transmission abnormality: If power transmission is unstable or signal interruption occurs, first check whether the connection line has problems such as short circuit and open circuit. Then test the contact resistance and insulation performance of the slip ring to determine whether the conductive parts or brushes inside the slip ring are faulty. For example, excessive contact resistance may be caused by brush wear or oxidation of the conductive surface, and the brushes need to be replaced or cleaned in time.
Abnormal noise or vibration: Abnormal noise or vibration when the slip ring is running may be caused by improper installation, component wear, insufficient lubrication, etc. Check whether the slip ring is firmly installed and whether the parts fit tightly; check the wear of the rotating parts and replace the seriously worn parts in time; check whether the lubricant is sufficient and add or replace the lubricant if necessary.
