Sealed Spherical Roller Bearing Size Chart

Sealed spherical roller bearing is an upgraded design of the spherical roller bearing. Like ordinary open spherical roller bearings, it has two rows of drum rollers, one spherical raceway on the outer ring and two rollers on the inner ring. The raceway is inclined at an angle relative to the bearing axis. The raceway has a certain radian. According to the different designs of the rollers and cages, there are different processing methods. In addition, there is a sealing design at both ends of the bearing (the sealing cover is made of nitrile rubber), which can prevent the entry of dust, particles, and dust, and can keep lubricating oil or grease in a sealed environment to lubricate the raceway and reduce The temperature of the bearing during operation), so as to ensure the normal operation between the raceway and the roller of the bearing, and ensure the service life of the bearing.

The radian design of the raceway makes it have self-aligning performance, so it is not easily affected by the angle between the shaft and the bearing housing on the error or shaft bending, and is suitable for the occasions where the installation error or the shaft disturbance causes the angle error. In addition to radial loads, the bearings can also withstand axial loads acting in both directions.

Sealed spherical roller Bearings have many kinds of cage according to their structure and materials. 

1. NSK sperical roller bearing types EA, C, CD, CA, 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.

2. FAG Spherical roller bearing E1 design provides an even higher radial and axial load carrying capacity and lower bearing temperatures along with improved safety against ring fracture, which increases both the operational reliability and the cost-effectiveness

of the bearing. The new E1 design covers the entire range of the previous E design. And also FAG can supply EAS.M Brass cage, TVPB, T41A, E1-TVPB, E1K.T41A,MB  brass cage design.

3. TKW Sealed spherical roller bearings are characterized by their self-aligning ability and high load-carrying capacity. They are designed to accommodate radial load or combined radial and axial load. Sealed spherical roller bearings have E brass cage, CC/W33, CA/W33, CCJA/W33, EJA/W33, VA405 cage design, most of the Top 10 bearing manufacturer in the world all have the sealed spherical roller bearings design, as well as TIMKEN Bearing, NTN bearing and ZKL Bearing,ZWZ Bearing.CoatMaster Bearing and EASIER brand from China.
