Self-aligning Roller Bearing

spherical roller retainer types EA, C, CD, CA,MB, E,K30, which are designed for high load capacity, are available.
Types EA, C, and CD have pressed steel cages; and type CA has machined brass cages.
Type EA has especially high load capacity, features low torque, and has a high-strength cage.
An oil groove and holes are provided in the outer ring to supply lubricant and the bearing numbers are suffixed with E4.
To use bearings with oil grooves and holes, it is recommended to provide an oil groove in the housing bore, since the depth of the groove in the bearing is limited.

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.

REGARDING ON BEARINGS
1) How to prolong service life of bearings?
Accurate installation and using, alignment, timely mnitor, re lubrication etc.
2) What is the reason for bearings failure?
It is usually incorrect using method, pollution, improper use of lubricant, damage happened in installation and handing, also including installation error, according to the traces can know the reason why it is failure.
3) How to choose bearings?
Analyse mechanical device and use conditions. clear the requirement of bearings. select tupe of bearings, select distribution way of bearings. select dimensions of bearing, select installation method of bearings.
4) When select bearings specifications, what do you need to consider?
The precision of the bearing (rotation precision, dimensional tolerances) internal clearance and preload bearing material and heat treatment. structure of cage and material.

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.
