How to improve the bearing life of woodworking beaded cold press?

The bearing is an important part of the complete set of modern carpenter's woodworking machinery equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its reversal accuracy. As our demand for bearings is increasing, the problems of premature damage to bearings and short life span have plagued every mechanical enthusiast.

What is the cause of premature damage to the bearings of woodworking cold presses? How to improve the life of the bearing? The more efficient analysis is as follows:

Under the action of relative load, the number of revolutions or hours experienced by the bearing before pitting occurs is called the bearing life. Bearings within this life expectancy should be fatigued and damaged on any of its bearing rings or rolling elements. However, in our daily practical application, it can be clearly observed that bearings with the same appearance under the same working conditions have very different practical lifespans. What is the cause of this? The company has summarized the following points:

1. The device is improper (about 16%)

1. When the force is too strong during the installation, hitting the bearing with a hammer on the top will cause greater damage to the bearing; it is also the main cause of deformation.

2. The device has an error or is not installed in the bearing position, resulting in too small bearing clearance. The inner and outer rings are not at the same center of rotation, forming different centers.

Proposal: Choose appropriate or professional bearing device tools, and use special equipment to detect the end of the device.

2. Pollution (about 14%)

Contamination can also cause premature damage to the bearing. Contamination means that sand, dust, metal chips, etc. enter the bearing. The main reasons include: opening the bearing package too early before use, causing pollution; the working environment of the device is not clean and causing pollution; the working environment of the bearing is not clean, and the working medium is polluted.

Proposal: Do not open the packaging of the bearing before use; adhere to the cleanliness of the device environment during installation, and clean the bearing to be used; strengthen the sealing device of the bearing.

3. Poor smoothness (about 50%)

According to investigations, poor smoothness is one of the main reasons for premature bearing damage. Including slippery agent or slippery oil not filled in time; slippery agent or slippery oil is not filled in place; slippery agent or slippery oil is not properly selected; slippery method is incorrect and so on.

Proposition: Choose the correct smoothing agent or smoothing oil, and use the correct smoothing filling method.

Fourth, exhaustion (about 34%)

Fatigue damage is a common damage method for bearings. Common causes of fatigue damage may be: long-term overload operation of the bearing; failure to repair in time; improper repair; aging of special-shaped grinders.　　 Advocate: select appropriate bearing types and replace tired bearings regularly and in time.
