6304 deep groove ball bearings
deep groove ball bearing 6308
Product Detail

Deep groove ball bearing is the most widely used rolling bearing. It is characterized by low frictional resistance and high speed. It can be used on parts that bear radial load or a combined load that acts on both radial and axial directions. It can also be used on parts that bear axial load..

1.Double sided steel seals

● The sealing material is made of stainless steel metal.

● It can effectively prevent foreign matter from entering the outside of the bearing

● Prevent damage inside the bearing and damage the bearing.



2.Double sided rubber seals

● The sealing materials is a combination of skeleton rubber

● It can effectively prevent foreign matter in the bearing,and impurities intrude into the bearing.

● Causes damage inside the bearing and damages the bearing



3.Open type bearing no seals

● No seals can directly see bare steel balls.

● Suitable for sealed environments;such as gearboxes,oily environments.



Application


● Industrial equipment bearings: mines, mining and smelters

● High-spec bearings for electrical equipment: power stations, gas turbines and electric motors

● Independent bearings and outer spherical bearings: packaging and printing, packaging equipment, food machinery and equipment

● Independent bearings and high temperature bearings: plastic, chemical fiber machinery, plastic film stretching

● Precision bearings for mechanical equipment: small toys, clocks, electronic equipment, audio-visual products.
