Square drill rod roller core repair
Roller square bushing is a tool used for oil drilling, mainly used in conjunction with rotary table tiles to drive square drill rods. It reduces friction with the square drill rod by rotating four rollers, thereby extending its service life.
The specific working principle of the roller square core is to reduce friction through the rolling contact of the rollers, making the drilling pressure more accurate, thereby improving the efficiency and accuracy of drilling operations.
Roller square core has the advantages of high precision, large load-bearing capacity, and long service life, and is suitable for applications under high-speed rotation and high load conditions.
1、 High precision
The rolling element of a roller square core bearing is composed of multiple rollers, and compared with traditional ball bearings, it has a larger contact area, thus having a stronger load-bearing capacity. At the same time, the roller diameter of the roller square core is larger, which can withstand larger loads and perform better under high-speed rotation and high load conditions.
2、 Long lifespan
Due to the larger contact area of roller square core bearings, their service life is longer under the same load. In addition, the compact structure of roller square bushing bearings can withstand larger loads in a smaller space, reducing the size and weight of components, and also lowering the maintenance cost of the machine.
3、 Wide applicability
Roller square core bearings are suitable for many application fields, such as manufacturing, aerospace, automotive industry, etc. Excellent performance under high-speed rotation and high load conditions, especially suitable for applications that require high precision and reliability, such as machine tool spindles, automotive engine support bearings, aviation engine intake valve bearings, etc.
