f. Main application: spherical roller bearings is mainly used for medium and large motors,

generators, internal combustion engines, gas turbines, machine tool spindles,  deceleration

devices, and material handling machinery and various types of industrial machinery.

g. Packing: individual box single plastic bag, cartons and wooden cases

h. Production range: standard and non-standard

2.Designs and structures:

TN1: Nylon retainer.
C: Stamped steel retainer and strengthened symmetric rollers; offers considerably higher load 

ratings than conventional designs for a broad range of applications and long service life. 

CA: Alternative design of C design; Precision-machined one  piece brass retainer and strengthened symmetric rollers; used to exchange with 

C design, especially for large size.                                                                             

MB:Twopiece precision machined brass retainer and strengthened symmetric rollers; equivalent to 

C design in load capacity.

 CC: steel cage, replace traditionalbrass cage.

E: Third generation design. 
The bearing contact is completely optimized and has improved stress distribution; offer much longer

 service life than normal designs.

3.Application of spherical roller bearings

Spherical Roller Bearings are commonly used in agricultural machines such as combined

harvesting machine, air-blower, paper-machine, textile machine, woodworking machinery,

overhead crane moving wheel and driving shaft as well as a large number of non agricultural

applications.
