Bearing seal ring is a ring cover composed of one or several parts, fixed on a ring or washer of bearing and contact with another ring or washer or form a narrow labyrinth clearance, to prevent lubricating oil leakage and foreign intrusion.Bearing dustproof sealing ring is to prevent dust and grease leakage.

Bearing speed is one of the most important factors affecting bearing temperature rise.The maximum allowable speed of the bearing, that is, the limit speed, decreases with the increase of the bearing diameter series and width series.

Heating of bearing system is a failure problem faced by many motor products. Both bearing manufacturers and motor manufacturers pay special attention to this problem.The direct consequence of the heating of the bearing system is that the heating of the bearing leads to the loss of grease, the failure of bearing parts due to heating, the rotation of the motor is not flexible or stalled, and the increase of heat conduction and current leads to the malignant accident of the motor winding burning in a very short time.

The Army confirmed that officers with the Army Criminal Investigations Service are investigating the theft of 130 tons of nickel-plated ball bearings at the White Sands Missile Test Site in New Mexico.

The role of forklift door frame roller is fork frame or between the door frame and the door frame plays the role of guide and force transfer forklift accessories, divided into side roller (longitudinal roller and transverse roller) and compound roller two, respectively installed in the forklift outside the door frame, internal door frame and fork frame.

In fact, made in China have already thoroughly remould oneself, our country's high-speed rail, for example, has the world's largest high-speed rail network, while huawei mobile phone and take the lead in research and development out of 5 g, the stability of xinjiang unmanned aerial vehicle (uav) and wireless image transmission, is a leader in science and technology, we going to talk about today is bearing areas in our country, bearing the problems, after all, China for many years,It is not easy to be sophisticated, so what is the true level of Bearing in China now?Let me break your stereotypes today.

The so-called bearing clearance, also known as bearing clearance, refers to the amount of movement when the bearing is not installed on the shaft or bearing box, and one side of its inner or outer ring is fixed, and then the side of the bearing clearance is not fixed to do radial or axial movement.According to the direction of movement, it can be divided into radial clearance and axial clearance.The operating clearance (called working clearance) has an impact on the rolling fatigue life, temperature rise, noise, vibration and other performance of the bearing.

High carbon chromium bearing steel is usually used for the ferrule and rolling body.CCr15 is used for most bearings, and CCrl5SiMn with good hardenability is used for bearing rings with large sections and rolling bodies with large diameters.High carbon chromium bearing steel is an integral hardened steel, its surface and heart can be hardened, is the best material for rolling bearings.

The role of rolling bearing is to transform the sliding friction between shaft and shaft seat into rolling friction. In the process of rolling bearing operation, rolling friction will cause bearing heating and wear. In order to reduce friction and damage, rolling bearing operation needs lubrication.

The high bearing capacity of roller bearings makes its application very wide. The design and processing of rollers are also developing continuously.A new type of tapered barrel roller bearing will be introduced below.

Cross roller bearing is a sub-industry in bearing classification.There are many different kinds of cross roller bearings according to different standards. XSU series is a basic series with large market usage. This paper takes XSU series as an example to explain in detail.

Bearing is one of the important "joint" of mechanical equipment, once bought fake goods bearing, can bring a lot of damage to machinery and equipment, if a large mechanical equipment because of fake goods bearing for repair, the losses during the basic is nearly ten thousand yuan, in order to let everyone know about fake goods bearing more, today to share some distinguish fake goods bearing techniques.What are the main characteristics of counterfeit bearings?What are the means of bearing fraud?How to distinguish true and false bearings?I hope it helps.

Therefore, please fully study the installation of bearings, that is, please carry out the installation of bearings in accordance with the operating standards including the following items

Bearing vibration is very sensitive to bearing damage, such as peeling, indentation, rust, crack, wear and so on will be reflected in the bearing vibration measurement, so, by using a special bearing vibration measurement device (frequency analyzer, etc.) can measure the size of vibration, through the frequency can not infer the specific situation of abnormal.The measured values are different due to the use conditions of bearings or the installation position of sensors, etc., so it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.

The change to the drum, also known as the guide drum, is a common key part of the belt conveyor, mainly used to change the direction of the conveyor belt or pressure the conveyor belt to increase the Angle of the transmission drum.
