Generally, tapered roller bearings are not allowed to have angle error, but the surface of the roller and raceway can be allowed to have an angle error of 2' to 4' after special design. Single row tapered roller bearings Single row tapered roller bearings can withstand axial loads in one direction.
Usually two single-row tapered roller bearings of the same structure are used in the two supports face to face or back to back. In order to ensure the good running state of the bearing, the tapered roller bearing, like other ball and roller bearings, must be applied with a certain amount of Minimal load, especially for high speed, high acceleration, or work under conditions with frequent changes in load direction.
Because, under these working conditions, the inertial force of the rollers and cages and the friction in the lubricant will adversely affect the rolling and rotation accuracy of the bearing, and there may be sliding between the rollers and the raceway that is harmful to the bearing. sports.
Often, the weight of the bearing support itself, plus the load on the bearing, exceeds the minimum required load. If the minimum load has not been reached, this type of bearing must be subjected to additional radial load, such as axial preload on the bearing to meet the minimum load requirements.
In the use of each product, we are most concerned about the core value of such products and the various factors that affect this core value. For tapered roller bearings, its use efficiency is greatly affected by its force.
