Rotor Housing Construction - Mazda RX-8 2004 Service Highlights

ROTOR HOUSING CONSTRUCTION

• Based on the SIP (Sheetmetal Insert Process) production method utilizing special steel on the inner surface
and 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.
