The line of slip rings is intended to provide solutions for moving data and power from a stationary structure to a rotating device. The offering now consists of a new 1-in. through-bore model. The line also includes bore sizes of 1, 1 1/2, 2 3/4, and 4 in. for transfer of signals and power up to 50 amps, 600 volts.

The new unit provides a 1-in. through-bore for routing of hydraulic or pneumatic lines and a 3-in. outside diameter. It is available with a choice of 15 amp circuits in 6-, 12-, 18-, and 24-ring configuration in four housing lengths. The design uses fiber brush contact technology.

A slip ring can be used in any electro-mechanical system that requires unrestrained, continuous rotation while transmitting power and/or data from a stationary to a rotating structure. A slip ring is also called a rotary electrical interface, collector, swivel, or a rotary joint. The slip ring is intended to improve system performance by simplifying operations and eliminating damage-prone wires dangling from movable joints.

The fiber brush technology is geared to provide advantages over conventional slip ring contacts, including multiple points of contact per brush bundle, low-contact force per fiber, low noise, and low-contact wear rates. Reportedly, fiber brushes do not require lubrication and produce virtually no wear debris.
