As slip ring professionals, we understand the importance of slip rings for spacecraft. However, due to the extreme temperature variations in the space environment, aerospace slip rings are subject to much stricter quality standards than those on Earth. After all, atmospheric slip rings can be repaired, allowing for a certain margin of error and failure rate. In contrast, a contact ring failure in aerospace can render a spacecraft inoperable or even scrapped. Unless it is a manned space station that allows for limited repairs, slip rings on other spacecraft should provide reliability close to 100%.

In critical spacecraft subsystems such as attitude control systems, suspensions, and solar array connections, aerospace slip rings are indispensable. The function of these components is similar to that of slip rings used in the atmosphere in that they are used to transmit signals and energy. However, the space environment presents some unique challenges. For example, in scenarios where power and signals are transmitted simultaneously, either slip rings or rolling rings can be used.

For large spacecraft, due to the need to transfer large amounts of energy between rotating joints, carbon brush slip rings are commonly used to solve this problem in the atmosphere. Although carbon brush contact rings are used in space, vacuum and weightlessness can lead to the formation of carbon dust during operation. With heavy wear and poor sealing, this can lead to short circuits. In addition, carbon brush contact rings take up more space, and spacecraft have very stringent space and weight requirements.

In this situation, rolling rings are the ideal solution. Due to their design advantages, rolling rings can transmit much more power than conventional slip rings of the same size, thus satisfying the need for powerful rotational transmission in spacecraft. In addition, rolling rings do not use carbon brushes, so they do not emit carbon dust, and their reliability is much higher than carbon brush slip rings.

As a recognized manufacturer with nearly 30 years of industry experience, JINPAT has strong R&D capabilities and extensive experience in developing slip rings that are resistant to extreme temperatures. JINPAT is fully capable of developing slip rings for the aerospace industry that can withstand high and low temperatures in outer space.
