This replacement bearing is an authentic component which is supplied directly from the original equipment manufacturer for use with Black and Decker and Dewalt sanders and angle grinders. Bearings are used to reduce friction between rotating parts, please make sure to check appropriate diagrams of your unit for the correct location and use of this hardware. Over time bearings tend to wear out and may begin to fail eventually requiring replacement to maintain peak performance. This part is made of high-quality metal and it is sold individually.

Black & Decker belt sander repair
A bearing worn out and melted plastic housing. Both parts are available from ereplacementparts.com at a very reasonable price and were shipped and received quickly. Repair was successful and I'm sure I will be using ereplacementparts.com in the future.
