  The shaft and bearing seat are non-standard sizes, resulting in the outer diameter, inner diameter and width of the bearing being non-standard sizes. In the cramped space, to ensure the load, it is necessary to increase the diameter, length and number of rollers, while ensuring the wall thickness and strength of the ring, as well as the ability of the bearing to have a longer distance axial displacement. Also take into account the amount of thermal expansion of the material under high temperature conditions, and when paired, the different cross section height difference of each bearing must be controlled within a very small tolerance range, and the tighter tolerance range control is a prerequisite for the same load between the bearings in the paired bearing.

In the process of cooperative research and development with Yongsheng Grain and Oil Machinery Co., LTD., Dingzhou City, Hebei Province, the research team faced a series of technical challenges for the special needs of oil pressing machinery bearings. Because the shaft and bearing seat in the oil press machinery are non-standard sizes, the outer diameter, inner diameter and width of the required bearings are also non-standard sizes. This requires both load protection in a limited space, but also by increasing the diameter, length and number of rollers to achieve this goal.

At the same time, in order to ensure the stability and durability of the bearing, the wall thickness and strength of the ring must also be guaranteed. In addition, because the oil press machinery will produce high temperature during operation, it is also necessary to consider the thermal expansion of the material to ensure that the bearing can still maintain good performance under high temperature conditions.

In the paired use of bearings, because the cross section height of each bearing may be slightly different, it is necessary to precisely control the tolerance range to ensure that the load is evenly shared between the bearings. This strict tolerance control is the key to achieving stable performance of paired bearings.

Through the unremitting efforts and technological innovation of the scientific research team, the non-standard bearings that meet the equipment needs of Yongsheng Grain and Oil Machinery Co., LTD., have been successfully developed, effectively helping the upgrading of enterprise equipment and improving the production efficiency and product quality of oil pressing machinery. This research and development achievement has not only brought economic benefits to the enterprise, but also provided solid technical support for the implementation of China's good grain and oil action.
