The rotational movement of the bearing is designed for rolling bearings and sliding bearings. The difference is whether the force of attraction occurs relative to the parts between each other by rolling or sliding elements. Today, we follow Wafangdian Jinrui to learn about the structure and functional application of rolling bearings.

Structure of rolling bearing

The rolling elements of the rolling bearing can be balls, cylindrical rollers, pin rollers, tapered rollers or barrels. Rolling elements generally follow a cage, keeping them at a uniform mutual distance, preventing them from touching each other. Needle roller bearings and spherical roller bearings, the cage also ensures the correct positioning of the rolling element shaft. The bearing can be removed, and the rolling elements are put together in the cage to give a more suitable bearing. For specific applications, with complete ball rolling bearings, cylindrical rollers or needle rollers can be used.

The standard material for sheet metal cages is steel, and copper is also used in certain applications. The strong cage is made of copper, steel, laminated fabric and other materials. Cages made of thermoplastic materials are also widely used, especially those made of polyamide and glass fiber reinforced. The ring and rolling elements are mainly made through hardened chromium steel, although case hardened steel is also used. The rolling bearing is on one or both sides of the open version or seal. The most common types of seal gap seals and lip seals.

Functional applications for rolling bearings

Each roller bearing design feature makes it particularly suitable for specific bearing applications. It is usually impossible to formulate effective bearing selection rules. Usually, several factors must be considered and weighed. In addition to load and speed, it is usually necessary to pay attention to influences such as temperature, lubrication, vibration, installation, maintenance, etc. In many cases, there is at least one main bearing dimension-usually the design of the adjacent building where the inner diameter has been defined.

A radial bearing in which the radial load of a rolling bearing is dominant. Most radial bearings can support a combination of loading, such as deep groove ball bearings, angular contact ball bearings, tapered roller bearings, and spherical roller bearings. Cylindrical roller bearings, most needle roller bearings, drawn cup needle roller bearings and needle roller and cage components can only support radial loads.

The main axial loading of the rolling bearing is described as the axial bearing. Axial spherical roller bearings and single-axial angular contact ball bearings can support combined axial and radial loads. Only applicable to other types of axial bearing axial load. If there is no radial space available, the bearing must choose a lower cross-sectional height, such as needle roller and cage components, with or without an inner ring needle roller bearing, deep groove ball bearing, spherical roller bearing series.

The size of the rolling bearing mainly depends on the size and type of load, dynamic or static bearing load capacity, and the service life and operational reliability of the bearing. The rotating bearing is subject to dynamic stress. If the bearing is subjected to static pressure, there is only a very slow relative movement between the bearing rings, if there is a rotational movement or the load occurs in a static state. The overall dimensions are the same, and roller bearings generally can accept higher loads than ball bearings.
