Ball Bearing 107AT

This is a Genuine Manufacturer Sourced replacement part used on Shimano Spinning Reels. This part is made out of Metal and it is Sold Individually. Ball Bearings are used to reduce friction between rotating parts. The balls or rollers take the load and spin, distributing the weight evenly while the minimal contact area of the ball reduces friction. This reduces wear on the tool and allows it to run smoothly. Bearings experience constant wear when the tool is in operation from pressure, heat, vibration and friction. Because of this, many Bearings need periodic maintenance or replacement. To replace this Bearing you would need a Screwdriver. First you would need to disconnect the Reel Handle. Then remove the Side Cover by loosening the Screws that hold it. You should be able to remove the old Bearing. Install new Bearing and Reassemble the Reel
