Seated rolling bearings have various forms due to different combinations of bearings and bearing housings. 2.2 Forms and features 1 Bearing with vertical seat 1 Bearing with vertical seat cylindrical bore (with stop screw) Use bearing UC2(X,3) series UCP2(X,3) ordinary product, L3 triple seal product, C, CD (FC, FCD) with steel plate cover or cast iron cover 1) UCP2(3) SC cast steel bearing box, L3 triple seal ring product, C CD (FCFCD) with cast iron cover tapered hole (with fasteners) using bearing UK2( X,3) series UKP2(X,3) ordinary product, L3 triple seal ring product, C, CD (FC, FCD) with steel plate cover or cast iron cover 1) UKP2(3)SC cast steel bearing box, L3 triple seal ring Product, C, CD (FC, FCD) with cast iron cover is the most representative type of rolling bearing with seat. The root of the bearing box installation part is provided with a reinforcing rib, so it is a high-strength structure for loads in all directions. Bearing components (UCPsc, UKPsc) using cast steel bearing housings have also been serialized and used in applications with strict load conditions. Install the bearing box on the machine body with 2 bolts. In the case of a tapered hole (UKP), the nominal model number of the applicable fastener is added after the nominal model number of the component. Main uses: transmission devices, general machinery, etc. Thick-walled vertical seat bearing with cylindrical hole (with stop screw) uses bearing UC2(3) series UCIP2 (3) ordinary product, L3 triple seal product, C, CD (FC, FCD) with steel plate cover or cast iron cover 1 ) Tapered hole (with fasteners) uses bearing UK2 (3) series UKIP2 (3) ordinary product, L3 triple seal product, C, CD (FC, FCD) with steel plate cover or cast iron cover 1) high-load belt stand Type seat bearing. The bearing housing with high rigidity due to the wall is most suitable for applications where there are high loads, vibrations, and shocks. The mounting bolt holes are drilled and machined holes, so the bearing box can be installed in the correct position with 2 bolts. Main uses: cranes, heavy objects handling equipment, quarrying machinery, ships, etc. Note 1) The contents of the components with dust cover are shown in the table below (all types are common) Diameter series symbol contents 2 C, CD With steel cover FC, FCD With cast iron cover XC, CD X05～X17 With steel cover X18, X20 With cast iron cover 3 C, CD with cast iron cover. Narrow belt vertical seat bearing: cylindrical bore (with stop screw) uses bearing UC2 series UCPA2 ordinary product, L3 triple seal ring product. In order to reduce the installation space, the bearing with vertical seat is designed. When installing the bearing box to the main body of the machine, use the two bolt holes provided on the bottom surface of the bearing box installation. Main application: roller conveyor, small installation space, etc. Center height belt vertical seat bearing: cylindrical (with stop screw) bearing UC2 series UCPH2 ordinary product, L3 triple seal ring product. Lightweight vertical block bearing with cylindrical bore (with stop screw) uses bearing SB2 series BLP2 bearing with vertical block designed for the purpose of weight reduction. When installing the bearing box to the machine body, use 2 bolts. Main application: general machinery with the goal of lightweight. Purification series bearing with vertical seat: cylindrical bore (with stop screw) bearing SU0 series UP0 ordinary product C, CD with rubber coating cover inner ring with anti-rust plating treatment of lightweight component ball bearings and special lightweight Bearing with vertical seat combined with alloy bearing box. It is a small, lightweight, and clean seated bearing with no oil-feeding type that is equipped with a bearing of 0 diameter series. Bearings and bearing housings will not rust for a long period of time, so they are most suitable for clean environments. When installing the bearing box to the machine body, use 2 bolts. Main uses: food machinery, pharmaceutical machinery, etc.
