Due to its small radial section size, good bearing rigidity and high radial load carrying capacity, LYC needle roller bearings are uniquely suited for applications where the radial device space is constrained. Swinging in the shaft and housing It can also be widely used. However, the needle bearing can only accept pure radial load; it can not restrain the axial displacement of the shaft and the bearing seat; the bearing device also does not allow the inner ring axis and the outer ring axis to have visual point errors.
Double row needle roller bearings Long cylindrical roller bearings NA, RNA type LYC standard needle roller bearings are NA type; outer ring has ribs or elastic locking rings on both sides; inner ring has no ribs. There are single row and double row needle roller two Layout type. Regardless of single or double row needle roller bearings; can be made with an inner ring type NA or no inner ring type RNA type layout.
The large-scale series of needle bearing outer ring has a ring-shaped smooth oil groove and a smooth oil hole. The outer ring assembly (outer ring, needle roller and cage) of the NA type needle roller bearing can not be separated; but if there is an inner ring; Can be separated from the outer ring assembly.
Needle roller without inner ring bearing directly touches the outer surface of the journal; it can further reduce the requirement of the azimuth dimension of the radial arrangement of the bearing housing. However, the hardness and dimensional accuracy of the bearing journal should reach the corresponding skill requirements of the bearing raceway.
NAV, RNAV type NAV type and RNAV type are full complement needle roller bearings without cage. It is a layout derived from NA type and RNA type bearings. Its bearing capacity is greater than that of NA type and RNA type bearings; but speed function Lower than NA type and RNA type bearings. Suitable for use under low operating conditions.
NAO type NAO type inner and outer rings have no ribs; there are single row or double row needle roller. Double row needle roller; outer ring has smooth oil groove and smooth hole.
K type
K type is also called "needle roller and cage assembly"; the layout bearing has no inner and outer rings. It is the smallest type of bearing in the radial dimension of the bearing. It uses the outer surface of the shaft and the outer surface of the bearing housing as a raceway; therefore; The hardness and dimensional accuracy of the shaft outer surface and the outer surface of the bearing seat should reach the corresponding skill requirements of the bearing raceway.
Long cylindrical roller bearing long cylindrical roller bearing; such bearing has the characteristics of similar needle bearing; but the radial section of the bearing is larger than that of the needle bearing; thus; can accept large radial load.
Long cylindrical roller bearings for roller and needle roller bearings; the ratio of length to diameter (length to diameter ratio) is greater than 3; the difference is that the roller diameter of long cylindrical roller bearings is greater than 5L. Therefore; Formally; long cylindrical roller bearings have many of the same layout as needle bearings.
The long cylindrical roller bearing is the same as the needle bearing; it can only accept the pure radial load; it can not restrain the axial displacement of the shaft and the bearing seat; when the bearing device is used; the visual point error of the inner ring axis and the outer ring axis is also not allowed.
The NAOL type NAOL type has the same layout as the NAO type needle roller bearing. There are no ribs on the inner and outer rings;
The NAL type NAL type has the same layout as the NA type needle roller bearing. The outer ring has ribs or elastic locking rings on both sides; the inner ring has no ribs.
