The through bore slip ring with specified dimension is a slip ring specifically designed for high-temperature environments, capable of operating in temperatures ranging from -40°C to +100°C. It is widely used in equipment such as food processing machinery and packaging machinery.

This slip ring also features a customizable through-hole design, facilitating cable routing in rotating systems with varying spatial constraints. Additionally, it offers multiple channels and supports transmission currents of 5A-20A or higher, enabling high-power transmission.

Features

Low noise

The precise-sized brushes and conductive rings of the through bore slip ring with specified dimension are in good contact. They do not cause abnormal noises due to excessive friction during operation.

High conductivity

The conductive parts of this slip ring are made of copper alloy, gold, silver and other materials. These materials have high conductivity and can effectively reduce resistance.

impact resistance

It is designed with a metal shell and a shock absorbing device or structure such as an elastic shock absorbing element inside. These designs help it protect the internal components and prevent them from being damaged under vibration.

FAQ

Q: What is the highest speed that the slip ring can adapt to?

A: Our through bore slip ring with specified dimension is a small and medium-sized slip ring with a simple structure, and the maximum speed may be one thousand revolutions per minute. We also have higher-speed slip rings for motor testing or aerospace fields, and their maximum speed can reach 5,000 revolutions per minute and higher.

Q: How do you ensure the signal transmission quality of the slip ring?

A: We add a shielding structure inside to block the entry of external electromagnetic interference, such as a multi-layer metal shielding layer made of copper foil and aluminum foil. We also perform quality inspections on them after production, including signal bandwidth testing, bit error rate testing, etc. This is to ensure that they can stably transmit signals at different frequencies.

Q: Can your slip rings be customized?

A: Of course! We provide many customized services for these slip rings. This includes signal type, component material, size, electrical parameters (number of channels, rated current, rated voltage), and protection level.
