What are the structural problems of imported bearing damage?

From the analysis of the damage of imported bearings, it is found that the structure has the following problems: 1. What’s wrong with the sealing? In particular, some bearing end caps need lubricant to penetrate. When the lubricant pH value is lower than 6, the bearing will be corroded quickly and t
Imported bearing maintenance needs to deal with the cause of damage

The dovetail guide noise of imported bearings and control measures. The raceway noise is a kind of slippery and continuous sound emitted by the non-standard bearing when the rolling body turns over on the dovetail guide surface when the single-sided bearing is running. It is a unique basic sound tha
How to improve poor lubrication of starter bearings

The starter bearing (commonly known as the copper sleeve) often wears too much in normal use, resulting in looseness of the journal and the copper sleeve, which eventually affects the performance of the starter. There are two main reasons why the starter copper sleeve is easy to wear:First, it bears
Causes, phenomena and treatment methods of abnormally high temperature of SKF operation

1. Causes of high temperature of SKF bearings:(1). It is possible that the cooling water of SKF bearings is interrupted, causing high temperature.(2). It is possible that the oil quality of SKF bearings is deteriorated, the oil itself is not clean or the oil is deteriorated during operation.2. Pheno

How to deal with stick-slip of bearing roller conveyor chain?

The bearing roller conveyor chain is sticky and slippery, and the production line is frequently interrupted, which reduces work efficiency, causes severe corrosion, and shortens the service life.Treatment method for sticky and slippery bearing roller conveyor chain:Even if the bearing roller conveyo
Five things to note when bearing operation

1. Mechanical damageIn severe cases, metal peeling and large-scale messy scratches occur on the contact surface; generally, bearing mechanical damage refers to the presence of grooves of varying degrees on the alloy surface of the bearing. The main reason for the mechanical damage of the bearing whe
Defects caused by heating of forgings

Beryllium oxide: Beryllium oxide not only causes a large loss of steel, but also reduces the surface quality of forgings and the service life of forging dies. If it is pressed into the metal, it will cause the forgings to be scrapped. Failure to remove beryllium oxide will affect turning.Decarburiza
How much does moisture affect bearing life?

The normal operation of bearings is inseparable from effective lubrication, but the harm of water to bearings may not be taken seriously by everyone. In fact, water has a great impact on the life of bearings. Only a small amount of water (close to 500ppm) can greatly reduce the life of rolling beari
How to install TIMKEN cylindrical roller bearings

Installation method: When using a tight fit inner ring, the installation method depends on whether the bearing has a straight or tapered bore. Then install the lock washer and lock nut or clamping end cover to fix the bearing on the shaft shoulder. After the bearing cools down gradually, tighten the
Several factors in selecting bearing types

1. Bearing radial loadThe bearing that mainly bears radial load is the radial bearing. The nominal contact angle of this type of bearing is a0<=45 0="" br="">N-type and NU-type cylindrical roller bearings can only bear radial loads, and other types of radial bearings can bear both radial loads and a
