Apex Seal Construction - Mazda RX-8 2004 Service Highlights

APEX SEAL CONSTRUCTION

• The special iron cast apex seals have been electronic beam processed to improve abrasion resistance on the
trochoid friction surface.
• The apex seal is comprised of two parts including a side piece set on the sharp end of an apex seal. The apex
seals maintain a gas seal while sweeping the trochoid surface by the combined force of the apex seal springs
and centrifugal force of the rotor rotation.
