Size: Model: 6304ZZ; Dimension: 13/16" x 2-1/16" x 9/16"(Inner Dia*Outer Dia*T)
Double-sided Steel Seal: This bearing is equipped with a double-sided steel seal, which effectively prevents the entry of dust and moisture extending the service life of the bearing and maintaining optimal performance.
Chrome Steel Material: Deep groove ball bearings are made of quality chrome steel with excellent strength, hardness, wear resistance and corrosion resistance. It can withstand significant radial and axial loads, providing reliable support in a variety of applications.
Grease Lubrication Method: This bearing uses grease as the lubrication method, which can provide a lasting lubrication effect during bearing operation, reduce friction and wear, protect the bearing, and extend the maintenance cycle.
Wide Application: widely used in high-speed rotating equipment, such as power tools, motors, fans, rollers, etc., as well as household appliances and office equipment. In addition, since the lubrication method is grease, the bearing is also suitable for some equipment where conventional lubrication is impossible or inconvenient, providing long-term and reliable lubrication.
