ZYS rolling bearing supplier Needle Roller Bearing HK2520 2RS with dimension 25X32X20 
 
The needle bearing is roller bearing with a cylindrical roller, which is both thin and long with respect to its diameter. In spite of the smaller crosssection, the bearing still has a high load bearing capacity. The needle bearing is equipped with thin and long rollers (roller diameter D ≤ 5mm, L/D ≥ 2.5, L means the length of the roller), therefore its radial structure is compact. When the inner diameter size and load capacity are the same as those of other types, the outer diameter is the smallest, which is particularly suitable for a support structure in which the radial installation size is limited.
 
Structure type
This type of bearing has a radial needle and thrust full of ball, or with a thrust ball, or with a thrust cylindrical roller, or with the angular contact ball into one, can withstand unidirectional or two way axial load. Can also be 
designed according to the user's specific structural requirements.
