30304 Tapered roller bearings

30304 Tapered roller bearings are key components in mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission of the equipment.

According to the bearing direction or nominal contact Angle, bearings are divided into radial bearings and thrust bearings. According to the type of rolling element, they are divided into: ball bearings and roller bearings. According to whether it can be aligning, it is divided into: aligning bearings, non-aligning bearings (rigid bearings). According to the number of rows of the rolling element, it can be divided into: single row bearings, double row bearings and multi-row bearings. According to whether the parts can be separated, it can be divided into: separable bearings and non-separable bearings. In addition, there are also classifications according to the shape and size of the structure.
