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 held in place with plated snap latches. The slip ring assembly end plates ("outboard bearings") are available for incoming wire hubs. The thru-bore is open, so the unit can be slid onto a host shaft. Common options include:
Special hub sizes or arrangements
Special shafts/flanges to match host equipment
Special drive hole locations or drive brackets
Extra gasketing for a tighter dust seal
Revolving Unit (RU) The NEMA 4 "RU" is a painted spun steel enclosure that completely contains the slip ring assembly. 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:
Heater strips to reduce internal condensation
Breather drains to reduce internal condensation
Special hub sizes or arrangements
Special flanges to match host equipment
Maximum operating speed: 125 rpm (1.5" bore); higher speeds attainable with optional carriage ball bearings.
