Types and characteristics of UC type bearings_UK type bearings_NA type bearings

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. 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 fixation with the shaft is carried out by fasteners. UK type bearings (with fasteners) are most suitable for long shaft applications. For UK type bearings, the nominal number of applicable fasteners is attached after the bearing nominal number. NA type bearing Cylindrical bore (with eccentric fixing ring) NA2 adds UC type bearing (with stop screw) to the bearing form with eccentric fixing ring. The grease-sealed deep groove ball bearing is a combination of a spherical outer ring with an oil supply structure, a cylindrical hole with an eccentric part on one side, a wide inner ring, and an eccentric fixed ring. The sealing device is equipped with an oil seal and a flinger. The fixation with the shaft is carried out through the following steps. Insert the eccentric recess of the eccentric fixing ring into the eccentric part of the inner ring, rotate the eccentric fixing ring and fix it on the shaft, then tighten the stop screw of the eccentric fixing ring on the shaft. This type of bearing is mainly used overseas. Therefore, this catalog does not include the dimension table of the seated bearing installed with NA type bearings. Please contact if necessary.
