The Baldor Tapered Spindle is engineered specifically for use with Baldor tapered shaft polishing motors. Unlike standard polishing motors that use straight shafts secured with set screws, Baldor motors feature a slight taper on the shaft. These spindles are designed with a matching tapered inside diameter, creating a secure friction fit without the need for set screws.
Installation is straightforward: the spindle is pushed onto the tapered shaft and then lightly tapped into place using a mallet or a piece of wood. Removal is handled by Baldor's built-in screw-off spindle remover, located inboard of the shaft—when unscrewed, it pushes the tapered spindle off cleanly.
Important: Because the inside diameter is tapered, no ID measurement is provided for these spindles. These spindles are compatible exclusively with Baldor tapered shaft motors and will not fit straight-shaft motors.
