Tapered roller bearings with bearing compound load (there are both radial and axial force) significant advantages and is widely used in the industrial field. 

Tapered roller bearings axial clearance is set correctly or not directly determine the operating life of the bearings, and clearance adjustment is a precision, high technology engineering, and often require special equipment for professionals and implementation, in particular in the field of mass production, such as automotive industry, rely on manual clearance of each bearing system adjustments will put an enormous amount of labor costs, and inefficient. 

If using special equipment for detection and clearance adjustment, you need a certain amount of investment in fixed assets and the corresponding maintenance costs. In view of this situation, the Timken Company with Set-Right ™ technology, use preset tolerance control method of tapered roller bearing clearance, avoiding assembling adjustments during the process, not only greatly improves efficiency, reduces production costs, but also to ensure that the precision of clearance adjustment. 

Traditional methods of clearance adjustment of tapered roller bearing using artificial or specialized equipment or torque measurement gap, a professional adjustment process is comparable with Set-Right ™ precision can be achieved, but there are some interfering factors and constraints. 

Through gap measurement and measurement method to adjust the clearance, the accuracy of measuring equipment, skills, structure design and calculation of influence of non-bearing parts turning torque, and so has higher requirements. Timken Set-Right ™ technology is defined as follows: by controlling the Assembly Assembly tolerance values of the variables and using probability theory and statistical theory, makes 99.73% tapered roller bearing clearance after Assembly to achieve the required clearance, avoiding the additional adjustment clearance process. Which covers the probability theory, statistical learning theory, dimensional chain calculation of lean manufacturing and Six Sigma concepts. This technique for decades has been adopted for many customers
