Mazda Race Rotor Bearing
12A & 13B

The Mazda Factory Race (MFR) rotor bearings for all 12A & 13B engines are the best bearings available of engine operation near or above 8500 RPM. The rotor bearings are manufactured with a deep groove for additional oil storage and offer an additional .0005" (approximate) clearance. These bearings can be used in 1973 and earlier engines by grinding off the indexing tab.
