Engine Bearings

Stationary Gear 13B Rear, Hardened, 360° Multi-Window RX7 Bearing 76-95

This is an RX8 “High Power” hardened gear. We have them machined to take the “everything BUT RX8” rear gear O-ring. The RX8’s have NO groove for the big sealing O-ring. The RX8 O-ring goes in the rear side housing. These gears have 360° oil feed to the “multi-holed” RX7 bearing (#11114).

This is the bearing we recommend for about all Rotary engines. With the “multi-window” feed it works better that the stock bearing. The RX8 eccentric shaft has a little bit more clearance than an RX7 shaft so with this bearing you have that little bit extra. We have used this combo on our Road-Race engines, SHIFTING at 10,000 rpm with no problems (yes, few other mods like oil pump, light rotors, balanced, etc.)
