Functional characteristics of tapered roller bearings
The type code of tapered roller bearing is 30000[5], and the tapered roller bearing is a separate bearing. Generally speaking, especially in the size range involved in GB/T307.1-94 "Rolling Bearing Tolerances", the outer ring and inner assembly of tapered roller bearings are 100% interchangeable.

Is there any difference between choosing imported bearings and domestic bearings?
In terms of imported bearings and domestic bearings, if it is to choose which product, more users will gradually shift their attention from the trust of imported bearings to the purchase of domestic bearings. Domestic bearings have gradually won the trust of users.
What are the classification of spherical bearings?
Top wire outer spherical ball bearing code: UC200 series (light series), UC300 series (heavy duty series), deformation products UB(SB)200 series. If the use environment is suitable for small environments, generally choose the UC200 series, and vice versa. Then choose UC300 series. Usually there are two top wire on the outer spherical ball bearing, the included angle is 120 °. Its characteristic is that when it is matched with the shaft, it uses the top wire to support the shaft to play a fixed role, but its matching environment requires a smaller oscillation. This kind of spherical ball bearing is more common, widely used in textile machinery, ceramic machinery and other manufacturing industries.
Cleaning bearing method
The most primitive bearing cleaning method is to use gasoline plus kerosene. However, with the development of industrial technology, water-based cleaning technology has gradually matured, and the cost has been significantly reduced. Therefore, more and more companies are beginning to favor water-based cleaning.
Inspection after bearing installation
Whether the bearing is installed correctly or not has a direct impact on its life and the accuracy of the host. If the installation is improper, the bearing not only has vibration, high noise, low accuracy, large temperature rise, but also has the danger of being stuck and burned; on the contrary, good installation can not only ensure the accuracy, but also greatly extend the life. Therefore, after the bearing is installed, it must be inspected.
