Review on Koyo BH 812 Bearing Complement Rotational by Tony Suggs

I used this bearing to balance the mower deck blades. I put the bearing on a 1/2" bolt and attached it perpendicular to the steel plate and after sharpening I put the mower blades on top to balance them. This works great for my blade hole size.
