Metal Shield Bearing 608zz Electric Tool Bearing for Angle Grinders, Cutters, Electric Hammers



Deep Groove Ball Bearings in Electric Tools

Deep groove ball bearings are essential components in electric tools, ensuring smooth operation, high efficiency, and durability. Commonly used sizes in electric tools include 608, 6000, 6200, and 6300 series bearings. Among these, the 608 bearing is particularly popular in small electric tools such as drills, grinders, sanders, and handheld mixers. Its compact size, high-speed capability, and low noise make it ideal for motor bearings in lightweight, high-performance tools.



Comparison of 608 and 6000 Bearings

Parameter 608 Bearing 6000 Bearing
Inner Diameter 8 mm 10 mm
Outer Diameter 22 mm 26 mm
Width 7 mm 8 mm
Speed Rating High Moderate
Load Capacity Light to Moderate Moderate
Applications Small Electric Tools General Electric Tools


The 608 deep groove ball bearing is widely used in small electric tools due to its compact design, high-speed performance, and ability to handle light to moderate loads. Its precision engineering ensures low noise and vibration, making it a preferred choice for motor bearings in handheld devices.
