Needle Roller Bearing 6829603

This authentic replacement part is designed for use with Ryobi cordless reciprocating saws. Ball bearings are used to reduce friction between rotating parts. A needle roller bearing is a special type of a bearing which uses long, thin cylindrical rollers resembling needles. The rollers take the load and spin, distributing the weight evenly while the minimal contact area of the roller reduces friction. Bearings experience constant wear from pressure, heat, vibration, and friction. Because of this, many bearings need to be periodically replaced. Make sure to check the diagrams of your model for the exact location and the correct installation of this component. It is made of high-quality metal and is sold individually. It is best to utilize a bearing press to remove the old part and secure the new one. You will need a screwdriver to take apart the housing in order to gain access to this needle roller bearing.
