UC type bearing cylindrical bore (with stop screw) UC2 (X, 3) ordinary product UC2 (X, 3) L3 triple seal product UC2 S6 stainless steel series consists of an outer ring with a spherical outer diameter surface equipped with an oil supply structure, a cylinder A grease-sealed deep groove ball bearing combined with a wide inner ring with a set screw in the hole. According to the sealing device, it is divided into two types: ordinary products (with oil seal and flinger) and triple seal products (attached symbol L3). The fixing with the shaft is carried out by 2 set screws installed on the inner ring. It is the most representative form of ball bearing for assembly. The UC2 S6 series uses stainless steel as the bearing material and is a ball bearing for components with excellent water resistance and corrosion resistance. Used as stainless steel series components. For the form and features of the set screw used in UC type bearings, please refer to 14 for use. UK type bearing tapered bore (with fasteners) UK2 (X, 3) ordinary product UK2 (3) L3 triple seal ring product is a combination of an outer ring with a spherical outer diameter surface equipped with an oil supply structure and an inner ring with a tapered bore The grease-sealed deep groove ball bearings.
