Cylindrical roller bearing

Cylindrical roller bearings include single row, double row, multi row, spiral roller bearing, and full complement cylindrical roller bearing. Commonly, the cylinders length of roller bearing is slightly greater than diameter. Compared to ball bearings, cylindrical roller bearing have a higher radial load capacity  

Single row cylindrical roller bearings are widely applied in railways, injection molding, electric motors and so on. Pressed steel cages and machined brass cages are common to see in cylindrical roller bearings for its high load rating.   

TBB double row cylindrical roller bearing has several designs such as with a cylindrical bore or tapered bore. Here are several designs, NNU design, NN design and NNUP design. Because of the bearing with two rows of rollers, their load carrying capacity is higher than single row.  

The structure of multi row cylindrical roller bearing is open or sealed. These bearing has a cylindrical or tapered bore. This kind bearing is widely used in rolling mill application and roller presses. Four row cylindrical roller bearings only accommodate radial loads.

The permissible operating temperature of Spiral roller bearing is limited by the following three items: the seals, the lubricant and the dimensional stability of the bearing material. You can according to the temperature requirements choose the suitable bearings in TBB. 

-The basic TBB full complement cylindrical roller bearing includes NCF, NJG, NNCL, NNCF, NNC, and NNF design sealed bearings. TBB roller bearing is characterized by high load carrying capacity at a moderate speed, long service life.
