Industrial slip ring

United Equipment Accessories recently partnered with an industrial winder company to build a 100+ circuit electrical slip ring. The company turned to UEA because we can produce low-volume, highly customized slip rings for specialized applications such as these. UEA has a dedicated team of design engineers to quickly get to work on our clients' custom slip ring projects.  

Industrial winder

This 3.0" thru bore slip ring with a custom mounting tube assembly is designed to be mounted horizontally inside an industrial winder. This slip ring consists of our 3.0" bore slip ring in conjunction with our 1.50" bore slip ring to keep the overall length to a minimum. This slip ring utilizes a separate the communication slip ring section inside a larger slip ring enclosure due to the total number of circuits. The custom, one-piece mounting tube weldment, and several ball bearings are used to ensure a structurally sound slip ring.

The 3.0" bore slip ring section contains circuits ranging from lower-level signal circuits to higher amperage power circuits. Detailed planning and organization are required to fit and route the wire & cable bundles to their termination point within the slip ring while keeping the signal circuits away from the power circuits.

The 1.50" bore slip ring section contains circuits ranging from control circuits to lower-level signal and communication circuits. A separate stainless-steel tube runs through the center of the 3.0" bore slip ring circuits, shielding the sensitive communication circuits from the VFD power circuits. This tube also contains a keyed encoder drive pin at the opposite end of the slip ring.

The combined assembly provides separate wire and cable side exits on each slip ring and separate wrap-around aluminum covers for easy access to each slip ring section. A customer-specified encoder mounting bracket is supplied for the encoder's easy attachment at the time of slip ring installation. At UEA, we look forward to challenging applications and work diligently with each customer to come up with a solution. Contact us today for your custom slip ring solution.
