Through Bore

Through Bore Slip Ring

The TB models are available with bore sizes .375” to 8”.

The TB 1.0 model is available in 6, 12, and 20 conductors. This model is designed to fit over a .375 to 1.00 inch diameter shaft and the NEMA 4X enclosure makes it suitable to operate in salt air environments. This assembly can be modified to rotate up to 3,000 rpm for short periods of time.

The TB 2.0 to 8.0 model is designed to fit over shafts from 2 to 8 inches with 4, 8, or 12 rings. If your application requires a nonstandard bore size, the next larger size will be built and a reducing sleeve will be installed with the required bore size for a nominal charge.
