Ball Bearing

This is an authentic Alpha replacement part. This ball bearing is used in the motor of tile saw. Ball bearings are found on the armature of the motor in your power tools, they are what allow parts within your tools and motors to spin or rotate smoothly. Ball bearings are used to reduce friction between rotating parts, which is why they are commonly used in power tools. Over time these ball bearing will wear down, inside your power tool there is a lot of heat and friction produced. Signs the ball bearing in your tool need to be replaced are excessive heat coming from bearing locations, your power tool will start to make unusual sounds, and you will notice the spindle/armature not moving as freely as it once was. Metal shields on either side of the bearing help limit the amount of dirt and debris getting into the bearing during operation. This bearing is made of metal, and is sold individually. Before starting any repair on your power tools be sure to disconnect the power, this will eliminate the risk of accidental start-ups.
