Which parts of the excavator need to be installed with self-lubricating bearings?

Self-lubricating bearings have irreplaceable and significant advantages over other bearings in the use of excavators due to their self-lubricating and maintenance-free characteristics, which can further improve the performance, reliability and service life of the equipment.

• Maintenance-free‌: Self-lubricating bearings do not require manual lubrication, which reduces maintenance costs and time. They are particularly suitable for heavy equipment such as excavators and can maintain stable performance under harsh working conditions. ‌
• Long life‌: Due to the excellent wear resistance and corrosion resistance of self-lubricating bearings, their service life is relatively long, which reduces the frequency and cost of replacement. ‌
• Low noise‌: Self-lubricating bearings generate less noise and vibration during operation, which helps to improve the working environment of the excavator and improve the comfort of operation. ‌
• High load capacity‌: Self-lubricating bearings have an appropriate amount of elasticity and plasticity, which can distribute stress on a wider contact surface, thereby improving the bearing's load capacity and adapting to the high-load working requirements of the excavator. ‌
• Protect the grinding shaft‌: A transfer film can be formed during operation to protect the grinding shaft without biting the shaft. ‌
  ‌Wide applicability‌: Self-lubricating bearings can work normally in harsh environments such as high temperature, low temperature, high humidity, and high corrosion, meeting the use requirements of excavators under various working conditions‌.

Self-lubricating bearings are used in various parts of excavators, and the main installation parts include:

• Boom‌: The boom is an important part of the excavator. The application of self-lubricating bearings can improve its stability and life.
• Bucket‌: The bucket is a key part of the excavator's working device. The application of self-lubricating bearings in this part can reduce friction and wear and improve the working efficiency of the bucket.
• Cylinder and its top and bottom‌: The cylinder is the core component of the excavator's hydraulic system. The application of self-lubricating bearings in the cylinder and its top and bottom can ensure the stability and reliability of the cylinder under high pressure and high-speed movement.
  ‌Other key connection parts‌: Such as bucket arm joints, connecting rod connections, etc. These parts need to rotate frequently and bear large forces during the operation of the excavator. The application of self-lubricating bearings can reduce friction and vibration and improve the working efficiency and stability of the excavator‌.
