The accuracy, performance, life and other indicators of customized Idler Sprocket with Ball bearing are determined by many factors, including whether the bearing is installed correctly or not and whether it is used properly. Therefore, special attention must be paid when installing and using bearings.

The accuracy, performance, life and other indicators of customized Idler Sprocket with Ball bearing are determined by many factors, including whether the bearing is installed correctly or not and whether it is used properly. Therefore, special attention must be paid when installing and using bearings.
Open the bearing package immediately before installing the bearing to prevent foreign matter such as dust from entering the bearing, which will affect the performance and life of the bearing. Generally, bearing grease can be filled directly without cleaning. Ordinary bearings can be filled with lubricating oil without cleaning. If it is an instrument or high-speed bearing, you need to use clean cleaning oil to remove the anti-rust agent on the bearing before installation. Bearings filled with grease can be directly installed and used.
1. Installation steps of customized Idler Sprocket with Ball bearing:
(1), cleaning the bearing and bearing-related parts
(2) Check the size and finishing of related parts
(3) Install the bearing
(4) Inspection after the bearing is installed
(5) Supply lubricant
Bearings with different structures, fits, and installation conditions have different installation methods. Generally, they are multi-axis choices, and the inner ring of the bearing needs an interference fit. Cylindrical bore bearings are usually pressed in with a press or hot-packed. In the case of taper holes, it can be installed directly on the taper shaft or with a sleeve. When installed to the shell, there is generally a lot of clearance fit, and the outer ring has an interference. It is usually pressed in with a press, or there is also a shrink fit method for installation after cooling. When dry ice is used as the coolant, the moisture in the air will condense on the surface of the bearing due to the installation of shrink fit. Therefore, proper anti-rust measures must be taken.
2. The use of customized Idler Sprocket with Ball bearing
Because the bearing is a precision component, its use must be carried out accordingly.
Precautions for the use of customized Idler Sprocket with Ball bearing:
(1) Keep the bearing and its surroundings clean.
Even small dust invisible to the eyes affects the normal use of miniature bearings. Therefore, it is necessary to keep the bearing environment clean so that foreign matter such as dust cannot enter the bearing.
(2) Use with caution.
In use, it is necessary to avoid strong impact on the bearing, causing scars and indentations, which will become the cause of accidents. In the case of severe impact, it will crack or break, so be careful.
(3) Use appropriate operating tools.
When using bearings, you must use appropriate tools and avoid using substitute tools.
(4) Pay attention to the corrosion of the bearing.
Sweat on your hands can be the cause of bearing rust. Keep your hands clean and try to wear gloves.


3. Damage to customized Idler Sprocket with Ball bearing
customized Idler Sprocket with Ball bearing is accidentally damaged prematurely and cannot continue to be used, as opposed to the fatigue life, it is called the quality service limit of failure or accident. Generally, it is due to careless installation, use, and lubrication, foreign matter invaded from the outside, and insufficient research on the thermal effect of the shaft and housing, etc. Regarding the damage state of the bearing, such as: the jam of the ring and the rib of the roller bearing, the reasons can be considered, such as insufficient lubricant, unsuitability, defects in the oil supply and drainage structure, foreign matter intrusion, bearing installation error, and shaft deflection. If the song is too big, these reasons will overlap. Therefore, it is difficult to know the real cause of the damage only by investigating the bearing damage. However, if you know the machinery used, the conditions of use, the structure around the bearing, and the situation before and after the accident, combined with the damage state of the bearing and several causes, you can prevent similar accidents from happening again.
