Frequently Asked Questions (FAQs)
A conductive slip ring is a high-precision electromechanical component. Before selection, several key parameters must be confirmed, such as rotational speed (RPM), current capacity, signal types, and the operating environment. You can fill out the inquiry form on our website, and our application engineers will assist you in selecting the optimal solution.
We maintain a constant inventory of Capsule Slip Rings and Miniature Slip Rings. For standard products like the Through-Hole series, we stock sub-assemblies rather than finished goods; these can be assembled and shipped within 3-7 days of an order. For non-standard models we have previously designed for you, all design data, materials, and process parameters are archived for even faster turnaround on repeat orders.
For Capsule Slip Rings, our standard ODs are 12.7mm and 22mm. For Through-Hole Slip Rings, standard ODs include 12.7, 25.4, 50, 70, and 100mm. If your application requires custom dimensions, please contact us.
Standard slip rings typically operate at 200–300 RPM. If your application requires higher speeds, please consult us; our high-speed series can reach up to 20,000 RPM.
When purchasing, you can specify dust-proof or waterproof requirements. For applications in harsh environments, we can provide protection levels up to IP68.
The lead time for custom designs depends on complexity; typically, it is 3–4 weeks. For repeat orders of previously customized products, the lead time is reduced to 1–2 weeks.
