What Is A Heavy Duty Ball Screw Support

With the increase of the automatic machine tool industry and the popularization of manipulators, more and more people use screw supports. When it comes to support housings, many people may only know that there are deep groove ball and angular contact housings, but do not know that there are heavy-duty types. What is a heavy duty type? What are the characteristics? With these questions, listen to our technical engineer's explanation, what is a heavy-duty ball screw support seat, let's explore together!

    Introducing heavy duty housings.

    Heavy-duty bearing housings are mainly used in machinery and other equipment, and can withstand excellent axial loads. Heavy-duty housings feature angular thrust ball bearings with a 60° contact angle. Due to the 60° contact angle design, the heavy duty housing has excellent axial load capacity and axial rigidity.

    Since general working machines require better positioning accuracy, the heavy-duty bearing housing does not subdivide the accuracy level, and the rotation accuracy of all high-precision bearings reaches P4 level, so that the bearing housing achieves excellent accuracy characteristics.

    In order to meet the application requirements of large axial load, the heavy-duty bearing seat of Shangyin can be divided into three combinations: DF, DFD and DFF. DF is a general form, which can bear positive and negative axial loads at the same time; DFD adopts the design of one bearing in one direction and two bearings in the other direction to locally enhance the axial load capacity in one direction; the combination of DFF type is two bearings Axial load capacity for enhanced direction change. Different combinations have different axial load capacity, and customers can choose the appropriate combination according to their needs.

    Bearing housing product code, WBK is a special support bearing housing for heavy-duty screw support housings.

    The inner diameter of the bearing is a two-yard number in mm, for example, 30 is 30mm, and 35 is 35mm.

    There are three bearing combinations: DF, DFD and DFF.

    Through the professional explanation of our technical engineers above, I think everyone knows what a heavy-duty ball screw support is, which environmental equipment should be used, when to use it, and how to choose it. As a decisive part of precision, everyday choices are very important. If you have anything unclear in the follow-up operation, please call our company.
