Great spherical roller bearing 21311CA W33

spherical roller bearing 21311CA W33

Spherical roller bearings are bearings with two rollers which mainly bear radial load,but also can bear axial load in either direction.

It has high radial load capacity especially working at heavy load and vibration load. What we should take attention is spherical roller bearings can not withstand pure axial load.

Because of its spherical outer ring raceway,it has great self-aligning and can compensate concentricity error.

Features:
1.The rollaway of outside race is in shape of sphere;
2.It has self aligning and it can make up for the error which from different angles.But its opposite gradient between outside and inside race is less than 3 degrees;
3.The structure principle and the character of the bearing are the same with self aligning ball bearing;
4.Under the condition of permissible volume of load and permissible speed of rotation, they can interchange;
5.Self aligning roller bearings apply to precise instrument, the electrical appliance of low noise, automobile, motorbike and other machinery. It is used the most widely in mechanical industry.

Suffix:

CA:Integral brass cage, double row symmetrical roller, inner ring ride;
CC:Two window-type steel cages, double row symmetrical roller, inner ring ride;
MA:Machined brass cage, outer ring ride;
MB:Machined brass cage, inner ring ride.

Company profile

Shandong Henggang Bearing Manufacturing Co., Ltd. is a professional manufacturer of high quality aligning roller bearings and cylindrical roller bearings. It is one of the largest manufacturers of aligning roller bearings in China. The company specializes in the production of spherical roller bearings. The company has a strong technical force, technical workers have undergone rigorous training and assessment, work style is rigorous and serious.

In order to further enhance the competitiveness of the company's products, the company expanded its scale in 2011, invested in the completion of two heat treatment lines, oxidation-free isothermal annealing and freezing quenching equipment, and put into the construction of a CNC roller processing workshop, fundamentally improving the quality of products, but also for the international brand. Our customers have provided a more competitive boutique bearing.

Therefore, one of our greatest advantages over other companies is that we can offer the best factory price on the same quality basis.
