What is a flanged roller bearings? The use and characteristics of flange bearings and installation

Features of flanged roller bearings

The biggest feature of flanged roller bearings is that the flange and the bearing are integrated. The series of products with flanges on the outer wheel make the axial positioning simple; the bearing seat is no longer needed, and it becomes more economical. When there is no connecting piece at one end of the shaft and it needs to be fixed on a plane such as a plate or wall, the flange bearing shows its advantage. In order to obtain the bearing's low friction torque, high rigidity, and good rotation accuracy, steel balls with a small outer diameter are used. The use of hollow shafts ensures light weight and space for wiring.

In the ultra-small diameter miniature bearings, it can be divided into ZZ steel plate bearing dust cover series, RS rubber bearing sealing ring series, Teflon bearing sealing ring series, flange series, stainless steel series, ceramic ball series, etc. Miniature ball bearings have a wide range of uses. It is suitable for products requiring high-speed rotation, low friction torque, low vibration and low noise.

How to extend the service life of flanged roller bearings

Flanged roller bearings mainly bear radial load, but also can bear radial load and axial load at the same time. However, I don’t know much about the life of flanged roller bearings. Here are 3 measures to extend the life of bearings:

(1) In order to enable the radial gap between the bearing holder and the bearing ring to be set larger than the eccentricity, the internal structure has been improved;

(2) Using FEM analysis, the strength of the retainer was improved by optimizing the shape and thickness of the plate;
(3) In order to prevent surface damage caused by the reduction of lubricating oil, a guide groove is designed in the bearing ring.

Precautions for installation of flanged roller bearings
For products such as flange linear bearings, the installation work must be optimized to be able to realize the optimized application of the bearing in the optimized installation state. This requires attention to these three key issues when installing bearings to ensure that the bearing installation work is done well:
1. Distinguish the components. Flanged roller bearings are composed of multiple components. Especially when installing, multiple components need to be installed together to form the entire system, and the installation position and method of each component are exquisite. In this case, in order to do the installation work well, it is required to distinguish all the components and not to confuse the components.

2. Clear steps. In order to ensure that the flanged roller bearing achieves the best installation state, it is required that you clarify the specific operation steps before installation, and strictly follow the prescribed steps during the actual installation to avoid operating problems affecting the bearing Installation effect.

3. Make sure the parts are in the correct position. All parts of the flanged roller bearing must be installed in the required position and in the required state to achieve a good installation effect. Therefore, if you want to install the bearing, it is very important to ensure the correct position of the parts.
