ROTOR HOUSING CONSTRUCTION

BHE011010908T02

• Based on the SIP (Sheetmetal Insert Process) production method utilizing special steel on the inner rotor surface casting aluminum around the steel circumference, the rotor housings employ the benefits of both the lightweight feature of aluminum together with the excellent strength of steel. By the addition of MCP (Micro Channel Porous) chromium plating to the inner trochoid surface, fine grooves have been made in the surface of the chromium plating for improved oil retention.

• A fluorocarbon resin coating has been added to the trochoid surface for improved initial break-in.
