Four-row cylindrical roller bearings are generally composed of one (two) inner ring and two outer rings. Domestic models generally start with the letters FC, FCD and FCDP.
FC is composed of one inner ring and two outer rings, such as: FC4054170; FCD is composed of two inner rings and two outer rings, such as: FCD76108300; FCDP is whether there are two inner rings and two outer rings, Two outer ribs and one spacer ring, such as FCDP138196715; international four-row cylindrical roller bearings are generally marked with SKF, NSK, KOYO, and domestic FC models.
SKF is generally a six-digit array starting with 31 or starting with BC4B, such as: 313822, 313823, BC4B322292A/HB3;
The Japanese model and the domestic model identification method have always been described here.
Four-row cylindrical roller bearings are mainly used in cold and hot rolling mills, pre-bullet machines and other steel rolling and aluminum rolling machines. Their structural characteristics determine that the installation, inspection, disassembly and cleaning of the bearing are very convenient.
Four-row cylindrical roller bearings have a large radial bearing capacity, high rotational speed limit, and allow axial displacement, but can only bear radial loads. They need to be paired with bearings that bear axial loads, and angular contact ball bearings are mostly used. , Thrust tapered roller bearings are used together.
According to the cage structure, four-row cylindrical roller bearings can be divided into three types: brass cage, pillar welded cage and car-made steel cage. According to the working conditions of the bearing, select the appropriate cage. Shelf material and structure.
