LONG CYLINDRICAL ROLLER BEARING

The roller bearing and long cylindrical roller bearing roller bearings are cylindrical, the length Lw and the diameter Dw ratio (Lw/Dw) greater than 3, the difference is that the diameter of the long cylindrical roller bearing roller is more than 5 mm, and the roller bearing roller diameter is less than 5 millimeters.
The basic structure of the needle roller bearing consists of a pair of ferrules and a set of rolling needles, with the outer ring leading the flange and the oil hole.
Because of compact structure, small radial size and large load capacity, needle roller bearings are suitable for parts with limited radial profile. The bearing generally can only bear radial load and can not bear axial load. Its limit speed is low.
The basic structure of the long cylindrical roller bearing consists of a pair of rings, a group of retainers and a long cylindrical roller. It is suitable for radial load in parts with limited radial size and low rotational speed. The outer ring axis and the inner ring axis are not allowed to be installed during installation.
