After more than 10 years of efforts, the company and the host manufacturers with the development of the chassis for the body, body parts, hydraulic components, including a variety of self-lubricating bearing materials, including bimetal boundary lubrication rolling bearings, metal-based self-lubricating bearings And metal plastic self-lubricating rolling bearings. These bearing materials have excellent wear resistance and dust resistance under high load conditions, and self-lubricating technology greatly increases the maintenance cycle of the bearings, improves the utilization of the equipment and reduces the maintenance cost.
