The grease bolt for the spherical bearings in the concrete pumps manufactured by Zoomlion Heavy Industry serves a critical function in providing lubrication and ensuring the proper operation of the bearings.

The primary role of the grease bolt is to deliver lubricating grease to the spherical bearings. It is designed to be connected to a grease gun or lubrication system, allowing grease to be injected into the bearings at regular intervals or as needed. The grease lubricates the contact surfaces of the bearings, reducing friction and wear during the operation of the concrete pump.

The grease bolt helps to maintain the smooth movement and articulation of the spherical bearings. By supplying an adequate amount of grease, it ensures that the bearings operate with minimal friction, preventing premature wear and damage. This promotes the longevity and reliability of the bearings, contributing to the overall performance of the concrete pump.

Regular lubrication through the grease bolt also helps to dissipate heat generated during the operation of the bearings. It aids in cooling the bearings, preventing excessive heat buildup that could lead to thermal damage or degradation of the lubricating properties.

Furthermore, the grease bolt allows for easy maintenance and servicing of the spherical bearings. It provides a convenient access point to inject fresh grease or flush out old and contaminated grease, helping to maintain the cleanliness and effectiveness of the lubrication system.
