Tapered bearing race mainly bear radial and axial combined loads.The bearing capacity depends on the raceway angle of the outer ring,and the larger the angle,the greater the bearing capacity.This type of bearing belongs to the separated type,and is divided into single row, double row, and four row tapered roller bearings based on the number of rolling elements in the bearing.The clearance of single row tapered roller bearings needs to be adjusted by the user during installation;The clearance of double row and four row tapered roller bearings has been given according to user requirements when the product leaves the factory and does not need to be adjusted.

The fixing methods for tapered bearing race usually include pressing fixation, screw fixation, heating method, and cold installation method.Specifically, as follows:
Press in and secure. Press the inner and outer rings of the bearing into the corresponding shaft and bearing seat, suitable for smaller sizes with sufficient strength and stiffness of the shaft and bearing seat.
Fix with screws. Fix the position of the inner and outer rings of the bearing by tightening screws on the bearing seat, suitable for small and medium-sized bearings.
Heating method. Heat the bearing to a certain temperature to expand it and press it into the shaft and bearing seat, suitable for larger sizes and softer shafts and bearing seats.
Cold packing method. Cold assemble the inner and outer rings of the bearing into their respective shafts and bearing seats, suitable for smaller sizes and softer shafts and bearing seats.
In addition, the fixing methods for tapered bearing race also include clamping fixation, welding, etc. The specific choice of method depends on the bearing's usage environment, conditions, and requirements.
