The TDO Type bearing is made up of one double outer ring, two single row inner rings and one inner ring spacer. The outer ring is provided with several lubrication holes.
The inner ring spacer has been adjusted to provide an end play suitable to each application. It is also possible to freely adjust the end play for use by removing the inner ring spacer, however, it requires time and labor.
Suitable to case where moment may act. Used for speed reducer, winding machine, etc.
The steep angle type (TDOS Type) having large contact angle has increased axial load capacity, and it widely used for worm shaft of medium, heavy duty applications, thrust bearing of reducers etc.
Tapered roller bearings are widely used in automobile, motor, gear, injection molding machines, machine tools, mining machinery, engineering machinery, motorcycles, office equipment, paper making machinery, pumps and compressors, wind power generator and so on.
