Stamping bearings are needle roller bearings manufactured using stamping technology. Stamping is a manufacturing process that uses dies and presses to process metal plates into the desired shape. NSAR are high-quality bearing manufacturer with a variety of bearings to supply.
Stamping bearings are a forming processing method that uses presses and dies to apply external forces to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining workpieces (stamping bearing stampings) of the desired shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and steel strips.
1. Low cost: Stamping technology is an efficient manufacturing process, so the cost of stamping bearings is lower than that of traditional needle roller bearings.
2. Light weight: The outer ring of the stamping bearing is stamped from thin steel plates, so it is light in weight.
3. Compact structure: The cross-sectional height of the stamping bearing is small, so the structure is compact.
Including:
1. Automobiles: Stamped bearings are used in various parts of automobiles, such as engines, gearboxes and suspensions.
2. Electrical appliances: Stamped bearings are used in various electrical appliances, such as washing machines, dryers and air conditioners.
3. Industrial machinery: Stamped bearings are used in various industrial machinery, such as pumps, fans and conveyor belts.
4. Office equipment: Stamped bearings are used in various office equipment, such as printers, copiers and scanners.
Stamped bearings are generally no longer cut, or only require a small amount of cutting. The precision and surface condition of hot stamping parts are lower than those of cold stamping parts, but they are still better than castings and forgings, and the amount of cutting is small.
Stamping is an efficient production method. Using compound dies, especially multi-station progressive dies, multiple stamping processes can be completed on one press, realizing fully automatic production from strip unwinding, leveling, punching to forming and finishing. High production efficiency, good working conditions, low production costs, generally hundreds of pieces can be produced per minute.
Stamping is mainly classified by process, which can be divided into two categories: separation process and forming process. The separation process is also called blanking, and its purpose is to separate the stamped parts from the sheet along a certain contour line while ensuring the quality requirements of the separation section. The purpose of the forming process is to make the sheet material plastically deform without breaking the blank, and make a workpiece of the required shape and size. In actual production, multiple processes are often applied to a workpiece. Blanking, bending, shearing, drawing, bulging, spinning, and straightening are several major stamping processes.
