FYH UC type bearing cylindrical bore (with set screw) UC2 (X, 3) General product UC2 (X, 3) L3 Triple seal product UC2 S6 A grease-sealed deep groove ball bearing composed of a cylindrical bore with a set screw and a wide inner ring. According to the sealing device, it is divided into two types: ordinary products (with oil seal and slinger) and triple seal products (attached symbol L3). The fixation to the shaft is carried out by means of 2 set screws mounted on the inner ring. It is the most representative form of ball bearings for components. The UC2 S6 series uses stainless steel as the bearing material, and is a component ball bearing with excellent water and corrosion resistance. Used as stainless steel series components. Please refer to 14 for the form and features of the set screw used in the UC type bearing. FYHUK type bearing tapered bore (with fasteners) UK2 (X, 3) General product UK2 (3) L3 triple seal product is composed of an outer ring with a spherical outer diameter surface equipped with an oil feed structure, and a tapered inner ring Grease-sealed deep groove ball bearings. According to the sealing device, it is divided into two types: ordinary products (with oil seal and slinger) and triple seal products (attached symbol L3). The fixing to the shaft takes place by means of fasteners. UK type bearings (with fasteners) are best suited for long shaft applications. For UK type bearings, the nominal model of the applicable fastener is appended to the bearing nominal model. FYHNA type bearing Cylindrical bore (with eccentric fixed ring) NA2 is a type of bearing with eccentric fixed ring added to UC type bearing (with set screw). The grease-sealed deep groove ball bearing is a combination of an outer ring with a spherical outer diameter surface with an oil feed structure, a cylindrical bore wide inner ring with an eccentric part on one side, and an eccentric fixed ring. Sealing device with oil seal and flinger. Fixing to the shaft is performed by the following steps. Insert the eccentric concave part of the eccentric fixing ring into the eccentric part of the inner ring, turn the eccentric fixing ring to fix it on the shaft, and then tighten the stop screw of the eccentric fixing ring on the shaft. This form of bearing is mainly used overseas. Therefore, this catalog does not include the dimension table of the NA type bearing housed bearing. Please contact FYH if needed.
