printing machine bearing is specially designed for printing machine bearings, mainly used to support various rollers of printing machine, such as plate rollers, rubber rollers, embossing rollers and paper transfer rollers, etc. These bearings play a vital role in the printing process, ensuring that the rollers work optimally together, thus affecting the quality of the printing 1.
Bearing type and purpose
There are many types of printing press bearings, including:
angular contact bearing : for printing presses with high precision requirements, such as model 7218C, suitable for angular contact applications .
needle roller bearing : often used in ink rollers and other parts of printing press, to provide high speed and low friction operating environment .
plane bearing : used for cylinder positioning of the printing press to ensure that the cylinder has no relative movement in radial and axial direction to ensure the printing accuracy .
First, printing bearing specifications
A printed bearing is a bearing specifically designed for printing presses, usually used to support printing shafts (plate shafts, ink rollers, etc.). The specifications of printed bearings are different from those of ordinary bearings, mainly including size, load capacity, applicable speed and so on.
Step 1: Size
Due to the variety of printing presses, the size of printing bearings will also be different. Generally speaking, the inner diameter range of printed bearings is 20mm ~ 300mm, the outer diameter range is 47mm ~ 460mm, and the width range of the shell is about 14mm ~ 80mm. The actual selection should be based on the printing machine model and use requirements to choose the appropriate size.
2. Load capacity
The specifications of printed bearings are also closely related to the load capacity. In printing presses, printing bearings need to withstand high loads and high-speed rotation. Therefore, the load capacity of printed bearings is higher, the static load is generally required to be greater than the dynamic load, and the carrying capacity is stable and reliable.
3. Applicable speed
The applicable speed of the printed bearing is generally between 1000 and 8000 RPM, and the applicable speed will be different according to different types of printing shafts. Generally, the appropriate printing bearing specifications should be selected according to the actual use to ensure the normal operation of the printing press.
Second, printing bearing FAQ
1. How to determine whether the printed bearing needs to be replaced?
In general, printed bearings need to be replaced when abnormal sound, vibration, and temperature rise occur. In addition, regular inspection of the wear of printed bearings, reasonable maintenance can also extend the service life of printed bearings.
2. How to properly maintain printed bearings?
Maintenance of printed bearings need to pay attention to the following points: regular cleaning and replacement of lubricating oil to ensure that the bearing surface is clean; Correct installation methods, including lubricating oil filling, bearing removal, etc.; Avoid impact loads on printing bearings when the press stops running.
3. How long is the life of the printed bearing?
The life of printed bearings varies according to the use and maintenance, usually between 1 and 3 years. Need regular inspection and maintenance of printed bearings, timely replacement.
Conclusion
Printing bearing is an important part of the printing press, the selection of specifications and reasonable maintenance of the printing press plays a vital role in the normal operation and service life. It is hoped that this article can help readers better understand and use printing bearings, so as to improve the production efficiency of printing presses.
