bedrijfsnieuws over A Detailed Analysis of Performance Differences Between Pancake and Through-Bore Slip Rings

In the fields of industrial automation, aerospace, and precision equipment, conductive slip rings serve as critical components enabling unrestricted 360-degree rotational transmission; consequently, the selection of the appropriate slip ring directly impacts the operational efficiency and stability of the equipment. Pancake slip rings and through-bore slip rings are two common types of slip rings, distinguished by significant differences in their structural design, performance characteristics, and application scenarios. This article will provide an in-depth analysis of the performance disparities between these two types to assist engineers in making informed selection decisions.

Also known as ultra-thin flat slip rings or disc-type slip rings, pancake slip rings feature a planar, low-profile design. Their defining characteristic is their extreme thinness—with minimum thicknesses ranging from 4 to 6 mm—combined with a relatively large outer diameter; this makes them ideally suited for installation environments where vertical space is limited but lateral space is ample.

Also referred to as hollow-shaft slip rings, through-bore slip rings feature a central bore that allows them to be mounted directly onto a rotating shaft. The size of the central bore varies widely—ranging from 0 mm to 600 mm—facilitating seamless equipment integration and cable routing.

• Precision Signal Transmission
• USB and Ethernet Signals
• High-Definition Coaxial Signals
• Hybrid Conductive Transmission
• Simultaneous Power and Signal Transmission

• Precision Signal Transmission
• Low-Current Transmission
• High-Current Transmission
• High-Voltage Transmission
• Multi-Channel Hybrid Transmission

Both types of slip rings utilize precious metal contacts and a vacuum potting process to ensure high stability and low signal loss.

IV. Summary
Disc-type slip rings and through-hole slip rings each possess distinct advantages; there is no absolute distinction between superior and inferior options. The key lies in selecting the appropriate type based on the specific application scenario.
Disc-type slip rings: Ideal for compact devices with height constraints that require precise signal transmission.
Through-hole slip rings: Ideal for industrial equipment requiring shaft-mounted installation and the transmission of high currents or high voltages.
Proper model selection can effectively enhance equipment performance, extend service life, and reduce maintenance costs.
