Review on 🔩 Enhanced Rannb Single Shielded Bearing Diameter for Optimum Performance by Bill Dahl

I had a 1978 Sears supercharger with an engine that was making a lot of noise. I thought this was the end after 42 years of service but I disassembled the electric motor and put these new bearings in and the supercharger is quieter than ever. I gave 4 stars instead of 5 as I don't know how long these bearings will last. Excellent purchase.
