Because there is no cage, full complement bearing.com/cylindrical-roller-bearings.html' target='_blank'>cylindrical roller bearings can accommodate as many rollers as possible, so they are suitable for bearing extremely heavy radial loads. In addition to radial loads, they can also bear certain axial loads. However, its allowable operating speed is much lower than that of cylindrical roller bearings with cages. Single row full complement cylindrical roller bearings also allow a few arc minutes of angular error between the inner and outer rings. Full complement cylindrical roller bearings have solid inner and outer rings. This bearing has as many rollers as possible. It is suitable for occasions requiring high radial load and demanding space. The bearing has high rigidity. Due to the friction between the rollers, in terms of rotational speed, the rotational speed of a full complement cylindrical roller bearing is much lower than that of a cylindrical roller bearing with a cage. The main application industries, machine tools, metallurgy, gearboxes, ports, printing machinery. Imported bearing products INA SKF IDC, etc. Full complement cylindrical roller bearings are designed to withstand heavy loads. Under the same width, compared with the bearing with cage, this kind of bearing can accommodate more rollers and has extremely high bearing capacity; but its allowable speed is much lower than that of the cylindrical roller bearing with a cage. Full complement double row cylindrical roller bearings have 4 structural types, 3 open structures and 1 sealed structure. All products are of non-separable design, with lubricating grooves and lubricating holes on the outer ring for easy lubrication. There is a fixed ring in the center of the outer ring between the two sets of rollers, which can prevent the rollers from running out and keep the bearing as one. The bearing can allow a certain axial displacement due to thermal expansion or between the shaft and the bearing housing. This displacement occurs inside the bearing, not the inner ring and the shaft or the outer ring and the housing. Therefore, the friction does not increase during the rotation of the bearing. Bearings of this type are suitable for use as floating end bearings. The outer ring of the bearing has no ribs, so the product of this structure can only bear radial load, not axial load. Axial positioning in one direction is possible. The outer ring is fitted with a snap ring at the other end, keeping the bearing in one piece. The snap ring is to prevent the bearing from being scattered during the handling process and cannot bear the axial load. This type of bearing can withstand high radial loads and unidirectional axial loads, thus enabling axial positioning of the shaft in one direction. In the other direction, it is used as a floating bearing. The bearing is filled with lithium-based grease and can be used between -40 and +80°C. This sealed bearing, under certain conditions, is maintenance-free. However, in a humid or heavily polluted environment, or when running at medium to high speeds, the bearing must be regularly lubricated, which can be lubricated using the lubrication holes on the inner ring or outer ring. The seal ring can also be removed from the bearing, and the bearing can be used as an open bearing.
