What are tapered bearings used for?
Double row tapered roller bearings are typically used in gearboxes, hoisting equipment, rolling mills and machines in the mining industry. Four row tapered roller bearings are used almost exclusively in work roll applications such as rolling mills.
What do the letters on bearings mean?
The first digit or letter or combination of letters identifies the bearing type and eventually a basic variant. The following two digits identify the ISO dimension series. The first digit indicates the width or height series (dimensions B, T or H). The second digit identifies the diameter series (dimension D).
What is eccentric bearing?
Eccentric roller bearing is a very practical types in all the bearings. It has a simple structure, including an outer ring, an inner ring, rolling element and rolling element basket. The hole of inner ring is eccentric hole and there is a longitudinal keyway on the medial wall of eccentric hole.

What are eccentric rollers?
In mechanical engineering, an eccentric is a circular disk (eccentric sheave) solidly fixed to a rotating axle with its centre offset from that of the axle (hence the word “eccentric”, out of the centre).
Are tapered bearings better than ball bearings?
Although tapered roller bearings can operate successfully at high speeds, ball bearings can exceed the tapered bearing’s speed limitations and generate less heat at the elevated speeds. Many tapered roller bearings are available as mounted units such as pillow blocks, flanges, piloted flanges, and take-up units.

What is name of split bearing?
Split spherical bearings are divided into two structures: Split Cylindrical Roller Bearings and Split Spherical Roller Bearings. It is mainly used for trunnion of converter on the steel-making. And this kind of bearing is easy for mounting, dismounting as well as protection and maintenance.
