With the development of mechanization, cylindrical roller bearings play a crucial role in mechanical rotation, especially in die machinery. Die machinery is equipment used for shaping objects and consists of many components. Among these, the precision, rotational speed, stability of the bearing components, and their compatibility with angular contact ball components significantly impact the performance of the die machinery. Cylindrical roller bearing components in die machinery have a relatively high damage rate, particularly during operations such as blanking, forming stamping, die forging, cold heading, extrusion, powder metallurgy pressing, and pressure casting, which cause significant damage to the bearings. To ensure the performance of die machinery, improve production continuity, and increase efficiency and benefits, it is necessary to intensify the inspection efforts for cylindrical roller bearing components, conduct frequent inspections, and increase the frequency of maintenance. Furthermore, it is required that bearing maintenance operators possess comprehensive knowledge of mechanical maintenance and upkeep. Below are the key points regarding the maintenance of cylindrical roller bearings:

1. Generally, try to minimize the switching frequency during machinery operation; excessive switching of equipment can cause cylindrical roller bearing components to wear out quickly and affect machining accuracy.

2. Regularly lubricate cylindrical roller bearings to extend their service life.

3. Fasteners such as cylindrical roller bearings are prone to loosening and need to be checked every 2-3 days to ensure the working precision of the equipment.

4. The outer rings of cylindrical roller bearings are prone to breakage, bending, and galling, and also require regular inspection and replacement.

5. After long-term use, the cutting edges of cylindrical roller bearings must be ground. After grinding, the edge surfaces must be demagnetized and must not be magnetic; otherwise, material blockage is likely to occur.

Bearing damage and failure are common problems encountered during bearing use. There are many forms of roller bearing damage and failure, including rust, transportation damage, installation damage, lubrication failure, abrasive wear, and fatigue. To maintain the bearing's performance in good condition for as long as possible, it is necessary to regularly perform bearing maintenance, inspections, and handle abnormal conditions to ensure operational reliability. Maintenance should be carried out periodically based on operation standards corresponding to the mechanical operating conditions. Content includes monitoring bearing operating status, supplementing or replacing lubricants for Type 2 bearings, and regular disassembly inspections. Through the above content, we can gain a detailed understanding of the maintenance knowledge regarding cylindrical roller bearings, which is very helpful for our better use in the future.
