TIMKEN bearing is a kind of precision mechanical support element. For example TIMKEN Bearing M88048. Users of TIMKEN bearing deeply hope that the TIMKEN bearing installed on the main machine will not be damaged and maintain its dynamic performance during the predetermined period of use, but the objective facts are sometimes not satisfactory and unexpected. TIMKEN bearing failure accident will cause heavy losses to users. A large number of failure analysis studies of rolling TIMKEN bearings show that the short life or premature loss of precision of TIMKEN bearings is due to material defects or improper manufacturing, but to a considerable extent, it is caused by not strictly complying with the requirements of TIMKEN bearings. , Maintenance, or caused by improper selection of TIMKEN bearing or actual load exceeding the rated load of TIMKEN bearing itself.
The early failure modes of rolling bearings mainly include rupture, plastic deformation, wear, corrosion and fatigue. Under normal conditions, they are mainly contact fatigue.In order to better use TIMKEN bearings, the following points should be noted:
Preparation before installation
1. Selection and requirements for installation site
The installation site should be some distance away from lathes, grinders and other mechanical equipment. The site should be cleaned and kept dry and clean frequently to prevent iron filings, sand, dust, and moisture from entering the TIMKEN bearing.
2. Check the TIMKEN bearing model and prepare the installation tools
Check whether the TIMKEN bearing model and size meet the installation requirements, and select the appropriate assembly method according to the structural characteristics of the TIMKEN bearing and the various parts that cooperate with it, and prepare the tools and measuring tools used for installation. Commonly used installation tools include hand hammers, copper rods, sleeves, special backing plates, screw clamps, presses, etc., with vernier calipers, micrometers, and dial indicators.
3. Inspect TIMKEN bearing assembly surface
If there are bumps, rust layers, wear debris, sand, dust and mud on the assembly surface of TIMKEN bearing and the surface of its mating parts, it is difficult to install the TIMKEN bearing, resulting in incorrect assembly position; second, these attachments form abrasives , It is easy to scratch the working surface of TIMKEN bearing and affect the assembly quality. Therefore, the shaft journal, the surface of the TIMKEN bearing housing hole, the end face of the shoulder, and the mating surface of the connecting parts such as bushes, washers, and end covers should be carefully inspected before installation. If there is a rust layer, it can be filed off with a fine file and polished with a fine emery cloth. At the same time, the attachments on the TIMKEN bearing assembly surface and its connecting parts should be removed.TIMKEN Bearing M88048 online, click here for more information about it.
The use of TIMKEN bearings
Precautions for use: Rolling TIMKEN bearings are precision parts, and their use must be carried out accordingly. No matter how high performance TIMKEN bearings are used, if they are used improperly, the expected high performance will not be obtained. The matters needing attention in the use of TIMKEN bearings are as follows:
⑴. Keep TIMKEN bearing and its surroundings clean. Even the small dust invisible to the eyes will affect TIMKEN bearings. Therefore, it is necessary to keep the surroundings clean to prevent dust from entering the TIMKEN bearing.
⑵. Use it carefully. A strong impact on the TIMKEN bearing during use will cause scars and indentations, which will cause accidents. In severe cases, it will crack or break, so be careful.
⑶. Use appropriate operating tools. Avoid replacing with existing tools and must use appropriate tools. Such as special sleeves, presses, etc.
⑷. Pay attention to the corrosion of TIMKEN bearings. When handling TIMKEN bearings, sweat on your hands can cause rust. Pay attention to the operation with clean hands, it is best to wear gloves as much as possible.
⑸. Do not unpack the TIMKEN bearing before the installation preparation is completed to avoid contamination.
TIMKEN bearing installation and cleaning
The correct installation of TIMKEN bearings affects accuracy, life and performance. Therefore, the design and assembly department must fully study the installation of TIMKEN bearings. Hope to install in accordance with operating standards. The standard operation items are usually as follows:
⑴. Clean the bearing and TIMKEN bearing related parts
⑵. Check the size and finishing of related parts
⑷. Inspection after TIMKEN bearing is installed
⑸. Supply lubricant
