BALL BEARING 874538SV

This is a genuine OEM replacement part, it is sold individually. This Ball Bearing is sealed on both sides. • 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.
