Compare spherical roller bearings E1 and CC
1.Structural characteristics
E1 type spherical roller bearing:
Adopting a symmetrical spherical roller design, the roller shape is more optimized, which helps to withstand forces in multiple directions.
Use two quenched steel stamping retainers, with an inner ring without a stop edge and a middle retaining ring guided by the retainer.
The middle retaining ring is close to the outer ring, which can improve the lubrication at the contact between the roller end face and the retaining ring, reduce bearing friction, and also help guide the roller in the non load area and assist the roller in entering the load area.
CC type spherical roller bearing:
Belonging to the second-generation design structure, it adopts stamped steel plate type retaining frame and reinforced symmetrical rollers.
Drum shaped rollers are installed between the inner ring with two tracks and the outer ring with a spherical track.
The curvature center of the outer raceway surface is consistent with the bearing center, giving it automatic centering function.
2.Performance advantages
E1 type spherical roller bearing:
Compared to ordinary roller bearings, the rated load has been significantly increased, usually by 20% to 35%.
Capable of withstanding forces from multiple directions, with high rotational speed and strong load-bearing capacity.
Due to the increased roller length and optimized lubrication design, its overall performance is more outstanding.
CC type spherical roller bearing:
It has good self centering function, which can automatically adjust the load and withstand axial loads in two directions when the shaft and housing bend.
Large radial load capacity, suitable for situations with heavy loads and impact loads.
The inner diameter of the inner ring is designed with a tapered hole, allowing it to be installed directly or installed on a cylindrical shaft using a tightening sleeve or disassembly cylinder.
3. Application Fields
E1 type spherical roller bearing:
Due to its high load-bearing capacity and excellent lubrication performance, it is commonly used in scenarios that require high loads and multi-directional forces, such as crushers, cement plants, and mixers.
CC type spherical roller bearing:
Widely used in various heavy equipment, especially those that need to withstand large radial and axial loads, as well as scenarios with automatic centering requirements, such as steel plant equipment, cranes, port elevators, paper machinery, etc.

Application
The main application areas of spherical roller bearings are:
1.Heavy Machinery:
In heavy equipment such as rolling mills, presses, mining machinery, large excavators, etc., spherical roller bearings are often used to support large rotating components such as bearing seats, gearboxes, etc.
2.Papermaking machinery:
The large drum, pressure roller and other components in the paper industry require high-precision and high stability bearing support, and spherical roller bearings are very suitable for this application due to their automatic centering ability.
3.Cement and building materials industry:
Ball mills, crushers, and conveying equipment in cement plants, as well as mixers and mixers in the building materials industry, often experience significant impact loads and vibrations on their rotating components. Spherical roller bearings can stably support these components and withstand loads.
4.Metallurgical equipment:
The rolling mills, continuous casting machines, hot rolling mills and other equipment in steel plants need to withstand high temperatures and heavy loads, and spherical roller bearings perform well in these environments.
5.Ports and lifting equipment:
Large lifting equipment such as port cranes, bridge cranes, and gantry cranes require their rotating components to withstand enormous dynamic loads and deflection moments. The automatic centering capability of spherical roller bearings makes them an ideal choice for these equipment.
6.Power generation equipment:
Large rotating components in power generation equipment such as wind turbines and hydroelectric generators, such as generator rotors and turbines, also require spherical roller bearings to support and stabilize their operation.
7.Other industrial sectors:
In addition, spherical roller bearings are widely used in various industrial fields such as textile machinery, plastic machinery, food machinery, rubber machinery, etc., providing reliable support for the rotating parts of various equipment.
Overall, spherical roller bearings have been widely used in various fields such as heavy machinery, papermaking, cement, building materials, metallurgy, ports, and power generation due to their excellent load-bearing performance, automatic centering ability, and wide adaptability.
