6202ZZ high temperature bearings mainly refer to the common bearing structure, using high temperature resistant materials, such as high temperature grease; and the bearing clearance is much larger than ordinary bearings , so it is usually not suitable for high speed operation, it is a high temperature low speed bearing. High temperature bearings are widely used in high temperature operation machinery such as metallurgy, kiln, glass, blast furnace, painting equipment.
