The following points should be noted to ensure that the bearings can work reliably
From the use point of view, to ensure that the bearings can work reliably should pay attention to the following points:

Depending on the operating conditions of the bearings and the requirements of the working environment on the degree of sealing, the engineering design is often a combination of various forms of seals to achieve a better sealing effect. The selection of additional seals for bearings should consider the following main factors:

The importance of sealing of spherical roller bearings
The sealing of the bearings is to make the spherical roller bearings to maintain good lubrication conditions and normal working environment, give full play to the working performance of the bearings and prolong the service life, the rolling bearings shall have a suitable seal to prevent the leakage of lubricant and the intrusion of dust, moisture or other dirt.

Failure analysis of sliding bearings
In the cement plant machinery and equipment in the sliding bearing mainly have copper tile, pasteurized alloy tile, phenolic resin tile, sliding bearing the main form of failure are heat, abnormal wear, burning tile. Sliding bearing failure form and scraping tile way and the corresponding lubrication mechanism has a close relationship.

Influence of bearing structure on vibration and noise
Falling body rolling sound, the noise in general, mostly in low speed and bear radial load of large bearings. When the bearing in radial load operation, bearing load area and non-load area, if the bearing has a certain radial clearance, non-load area of the rolling body and the inner raceway does not contact, but because of the role of centrifugal force may contact with the outer ring, in low speed, when the centrifugal force is less than the weight of the rolling body, the rolling body will fall and collide with the inner raceway or cage and stimulate the inherent vibration and noise of the bearing.

Repair methods for mechanical bearings
Bearings are quite common in our life, bearings are an important part of machinery and equipment, but inevitably there will be a variety of problems in the process of use, in machinery and equipment, the engine state has a direct impact on the service life and efficiency of machinery and equipment.

Commonly used bearing materials and description of steel categories
According to the cross-sectional shape of round steel, flat steel, square steel, hexagonal steel, octagonal steel, angle steel, I-beam, channel steel, d-beam, b-beam, etc.

How to check the radial clearance of rolling bearings?
The pressure lead method and the stopper method to measure, radial clearance translation in the bearing code is not marked, bearing clearance according to the size of its inner diameter and different, check the table to determine, in general rolling bearing radial clearance can not be greater than three thousandths of the bearing inner diameter, radial clearance of short cylindrical bearing to the heart can not be greater than two thousandths of the bearing inner diameter.

What is the general inspection method of bearings?
Various mechanical scars, such as abrasions, scratches, indentations, bruises, etc., can cause poor bearing installation, resulting in biased loads and stress concentrations, resulting in a decrease in rotational accuracy and service life.
