roller bearing

BS2-2208-2CS/VT143 BS2-2208-2RS/VT143 double row sealed spherical roller bearing BS2-2208-2CS 40x80x28mm There are two designation systems for sealed spherical roller bearings. One identifies sealed bearings in the standard ISO dimension series and the other extended width versions. Below is shown how the two designation systems are to be interpreted. Other suffixes, denoting special bearings or frequent variants, e.g. radial internal clearance other than Normal, are added according to the standard designation system

Description: Single-row cylindrical roller bearing usually refers to the bearing which is subjected to radial force. Compared with ball bearings of the same size, the bearing capacity in radial direction is increased by 1.5-3 times, and it has good rigidity and impact resistance. It is especially suitable for the shaft which is rigidly supported, also supports short shaft and causes axial displacement due to thermal elongation, and the machine accessories which need separate bearings for installation and disassembly.

Adjusting the axial clearance For the installation of tapered roller bearings, the axial clearance can be adjusted by adjusting nuts on the journal, adjusting washers and the threads in the bearing housing holes, or by using pre-tensioned springs and other methods. The size of the axial clearance is related to the arrangement of the bearing, the distance between the bearings, and the material of the shaft and the bearing seat, which can be determined according to the working conditions.

Needle roller bearings (needle bearing) is a cylindrical roller with a roller bearing, relative to its diameter, roller both thin and long. This is called needle roller. Despite having a smaller cross-section, has a higher load bearing capacity, equipped with a thin and long needle bearing roller (roller diameter D<5mm, L / D>2.5, L is the length of the roller), therefore radial structure is compact, its diameter size and load capacity and other types of bearings, minimum diameter, especially for radial mounting dimensions restricted support structure. According to different occasions, can be used without inner ring of the bearing or needle roller and cage assembly, when the surface of the journal bearing surface and shell holes as bearing directly match the outer rolling surface, in order to ensure the load capacity and operating performance and have the same ring bearing, shaft or housing bore raceway surface hardness, machining accuracy and surface quality should be similar roller bearing rings. Such bearings can only bear radial load.
