Sealed spherical roller bearing is one kind of spherical roller bearing,also named sealed self-aligning roller bearing,this kind of bearing are widely used in heavy duty capacity applications,it consist of double row drum rollers and inner ring,outer ring and cages,most of the spherical roller bearing are made of high quality chrome steel as well as element,but cage has so many kind of design according to material and

design,brass cage,pressed steel cage,nylon cage,it depend on different manufacturer to make sure the best solution for the application,so it can the reliable moving and long service life.
 
The most normal cage design of sealed spherical roller bearing is brass cage(CA) and Pressed steel cage(CC),it adopt NRB material seals to prevent the dusty away from the internal of bearing,its better design for lubricatioin than open spherical roller bearing,sealed spherical roller bearing can be working reliable under the temperature -40~120 ℃.
 
Advantage of sealed spherical roller bearing
* lower frictional torque compared to the competition
* environmentally friendly characteristics
* lower grease consumption and disposal costs
* no requirement for expensive relubrication systems
* reduced maintenance outlay
* simple reconditioning of series 240 and 241
* longer operating life of the bearing.
 
Sealed spherical roller bearing can be used in Continuous casting plant,Elevator systems,sealed spherical roller bearing can be tapered bore and cylindrical bore,this design can save cost for the customers,and decrease the maintenance of the machine,improve the working efficience.
