Self-lubricating properties
This kind of bearing uses a sintering process to evenly inject lubricating oil into the material to form a self-lubricating system. During use, as the bearing surface temperature rises, the internal lubricating oil will automatically be released to the sliding contact surface to provide continuous lubrication. This not only effectively reduces friction, but also reduces the noise generated during operation. In addition, the self-lubricating performance also significantly improves the operating efficiency of the equipment, especially in equipment that operates at high speed or for a long time, significantly reducing downtime and costs related to equipment lubrication.
Flange design
The flange construction provides significant advantages for the mounting and positioning of such bearings. The flange part can fix the bearing position during the installation process, and at the same time play a role in load dispersion to prevent component damage caused by concentrated stress. In addition, the flange design also enhances the bearing's ability to prevent loosening, especially under conditions of high vibration or severe movement. The installation process is simple and does not require additional complex fixtures, thus improving the stability of the equipment and reducing assembly difficulty and time.
Abrasion and pressure resistance
The high-strength oil-impregnated bronze material produced using a sintering process gives this bearing excellent wear resistance. Even in high-frequency sliding friction environments, it can still maintain stable performance and will not wear out quickly. In addition, this material has extremely high compressive strength and can easily handle the operation requirements of equipment under heavy load and high impact conditions. This characteristic is particularly suitable for critical components in industrial machinery and automotive fields, ensuring long-term reliability under harsh conditions.
Low maintenance requirements
The existence of self-lubricating function makes the bearing almost no need for additional lubricant in daily operation, greatly reducing the maintenance workload. Its excellent corrosion resistance also reduces the risk of damage caused by harsh environments. For example, this kind of bearing can still maintain its superior performance in working environments that are humid, dusty or exposed to chemicals. This low-maintenance feature is ideal for equipment that is remotely controlled or difficult to access frequently, helping to reduce operating costs due to maintenance downtime.

Application areas of this product
This bearing plays a vital role in micro motors, especially in small household appliances, power tools, toys and electric vehicles. Micro motors are usually compact and require efficient power transmission and operation in a limited space. Self-lubricating bearings can reduce friction, reduce power consumption and heat generation during motor operation, thereby improving motor efficiency. Because this bearing does not require external lubricants, it reduces lubricant consumption and maintenance requirements, further enhancing the reliability of the motor. In addition, the flange design helps ensure that the bearing can be accurately positioned during installation, providing more stable support. By effectively reducing vibration and noise and extending the life of the motor, it is particularly important in micro motors that require low noise and efficient operation, and is widely used in various consumer electronics, power tools and portable electric devices.
