slip rings

Slip rings are some of the less popular electromechanical devices, despite their widespread applications. This is primarily because these devices are application-specific. Manufacturers design slip rings to operate in particular equipment under specified conditions. As such, you must purchase slip rings with the right specifications for the intended application. Nevertheless, slip rings play the same role regardless of size, type, and specifications. They are designed to transfer current (power), data signals, or both from a stationary part to a rotating part. The design comprises two major components, the fixed brushes and rotating metal alloy rings. When looking for a slip ring, it is vital to find the ideal model for your purpose, which may require customization. Here are three steps to help you select the proper slip ring:

Step 1: Outline All Your Requirements

The first step to choosing a slip ring is outlining all the unique requirements and specifications needed. While slip rings play the same central purpose of converting signals and current between fixed and rotating parts, each works in a specific environment and machinery. For instance, if your application requires miniature PCB slip rings for smart toys, a through bore, or USB design wouldn’t work. The model and specifications of a slip ring depend on its application. This includes the equipment where the slip ring will be installed and a unique operating environment. For example, if your slip ring is to be used outdoors, it must be waterproof and weatherproof. Similarly, if you intend to use it in mining, enormous heights, and other high-risk operations, you should inform the vendor so that they can include fundamental properties. The application will determine the volume, thickness, material, dimensions, and other specifications. When outlining your requirements, focus on the following aspects:

1. Type of Slip Ring

Through bore (also Through hole), Pancake, PCB, Fiber Optic and USB slip rings are the most popular types you will come across in different devices. Each type has unique features and applications. There are also variations within each type. For instance, slip rings used in tiny home smart toys are different from those used in military applications. Narrow your search to vendors that offer the type of slip ring you are looking for, although it is recommendable to research if your application could benefit from a different or custom design.

2. Application Minimum Specifications

Each application requires a specific type of slip ring with precise specifications for size, volume, dimensions, material, and properties. As such, you should make sure you identify the minimum specifications required for the slip ring. Some materials used in PCB slip rings, for instance, may pose a risk to the user, equipment, or both. Because of this, you should look up the individual features and properties to find out if the brand meets minimum government specifications. The device should be the perfect fit for your application, including the equipment and operating conditions.

Step 2: Find Reputable Vendors

It is crucial to find reputable vendors that can guarantee high-quality slip rings for your application. Slip rings are specialized electromechanical devices that are customized to specific applications. What’s more, there are a few hundred slip ring vendors, which naturally reduce the number of substandard offers in the market. However, not all vendors are equal and you should never assume all models from a popular brand are of high quality. When selecting slip rings, it is essential to purchase from reputable manufacturers and models that have remarkable reception in the market. The easiest way to gauge if any given product or service is dependable is through market reputation. You can check the customer reviews, expert ratings and overall market share that the brand commands. Some of the popular slip ring brands include Senring, Moflon, Rotarx, and JINPAT, although you can find several other commendable offers. Once you have a couple of reputable manufacturers that offer the exact specifications you seek, compare them to find the best solution. Make sure you review both the brand and the individual model. For instance, Mouflon might have several lines of slip rings, but their MT Series receives a better rating.

Step 3: Customize Your Slip Ring

Slip rings are available in different types are demonstrated above. As such, you can find standard models, especially those designed to work with popular electric motors. However, these devices will most likely require customization when used for other applications. This is why it is recommended to outline your specifications before anything else. The process is much easier if you already have a typo or an old slip ring you can use for reference. However, you can always ask for professional advice from your vendor. You can also do this in the first and second steps to have an idea of the unique specifications required. Before ordering slip rings, you should review the order instructions to ensure every detail is correct. You must also inform the manufacturer of all crucial operating conditions and properties required. For instance, some applications require thing lightweight PCB slip rings while others call for dense metal alloys. As such, you will need custom slip rings. Advancements in technology may also call for newer models, features, or device characteristics. You can choose a modern slip ring that features more circuits, sturdier alloys, and easy maintenance.


Selecting a slip ring is all about finding the proper device for your application. There are many slip rings in the market and vendors all promote their offers as the best. Nevertheless, you can easily distinguish trustworthy and reliable devices from the rest. When selecting a slip ring, the priority must remain to find functional models for your equipment and application. You can also consider modern advancements and additional properties. If you are having trouble finding the slip ring you need, it is recommended to ask your vendor. Most slip rings work with specific equipment so you can quickly compare existing models designed for your machinery. Once you know what you are looking for, the remaining part is to find reputable vendors that can meet your needs. You can also compare prices to find affordable offers, although this should be the last review once you have the shortlist of vendors capable of meeting your demands.
