Wrap-Around Enclosure

The NEMA 1 Wrap-Around Enclosure is available for all bore sizes. It features a rolled, brushed stainless steel panel that wraps around the body of the slip ring.

It is available in 1.5", 2.5", and 3" O.D. shaft sizes. The cover is bolted to the base ("entrance ring") with a rubber gasket between.  Brush wiring enters through a 1" NPT hub mounted on the entrance ring. A shaft and shaft flange are provided; the shaft runs on a double ball bearings. Common options include:
