A set screw shaft attachment method is the most common means of securing a mounted ball bearing to a shaft and also the easiest to install. The Dodge mounted ball bearing offering is engineered with a 65 deg set screw angle. This ensures the maximum grip onto the shaft, especially when using premium cup point set screws with the high quality manufacturing of the Dodge insert.
