E Spherical Roller Bearings

E-type spherical roller bearings are a type of spherical roller bearings. These bearings have a high load-carrying capacity, can withstand bi-directional axial loads, and, at the same time, have a good centring, which can compensate for coaxial errors. TFL Bearings can provide standard sizes as well as customized E Spherical Roller Bearings in a variety of sizes. Standard sizes are fully stocked and can be delivered quickly. If you have special size requirements, you can also contact us for customization.

Features of Spherical Roller Bearings Type E

Internal structure: This type of spherical roller bearing has a two-piece hardened steel stamping cage, an inner ring without a retaining edge and a center retaining ring with a guide guided by the cage.

Features: The middle retaining ring close to the outer ring can improve the lubrication of the roller end face and retaining ring contact; its role is to reduce bearing friction, help in the non-load area to guide the roller, and assist the roller into the load area. At the same time, the roller length is increased, so the rated load has a greater increase. The load rating can generally be increased by 20% to 35%.

Areas of Application for E Spherical Roller Bearings

E Spherical Roller Bearings can withstand multi-directional force, high rotational speed, and strong load-bearing capacity and has a wide range of applications.

Main applications: It is mainly used in paper-making machinery, gearboxes, etc. It is also widely used in the construction and metallurgy industry.

What Is the Difference Between Spherical and Cylindrical Roller Bearings?

1. Load-carrying capacity: Spherical roller bearings can withstand large radial loads and bi-directional axial loads; cylindrical roller bearings mainly withstand large radial loads.

2. Centring: spherical roller bearings have an automatic centring function, and can adapt to the angular deviation between the shaft and bearing housing; cylindrical roller bearings do not have centring.

3. Structural characteristics: spherical roller bearings have an outer raceway for the spherical shape, and the inner ring has two raceways, cylindrical roller bearings. The outer ring and inner ring are cylindrical.

Why Is It Called a Spherical Roller Bearing?

Spherical roller bearings are called "spherical" because they have the following characteristics:

The raceway surface of the outer ring of this kind of bearing is a spherical shape centred on the midpoint of the bearing, which makes the bearing able to automatically adjust the position of the shaft center to a certain extent in order to adapt to the different centring conditions that may exist between the shaft and the bearing housing, thus reducing the adverse effects brought about by mounting errors or shaft deflection, etc., and maintaining a better running performance.
