Precision Cold Rolling Technology for Bearing Bushings
Precision cold rolling technology is an advanced bearing manufacturing process used to produce bearing bushings. The technology utilizes cold rolling die to create fine surface with very good mechanical properties and high accuracy. This type of advanced bearing manufacturing process can be applied for high-precision bearing bushings and for simple rollers and bearings. Cold rolling is widely preferred for its reliability, accuracy, and excellent surface finishing.
The precision cold rolling technology utilizes a cold rolling die that is heated to a preset temperature. The die is then inserted into a power press, which forces the material through the cold rolling die at a very high speed. The temperature of the die will be controlled carefully to offer the desired result. Once the material passes through the die, it is then formed into the required bearing shape. The process can be used for nearly any type of bearing, including basic cylinder-shaped rollers, deep groove bearings and contact thrust bearings.
The most notable advantage of this technology is that it offers extremely accurate and consistent results. The process ensures a constant level of surface geometry and accuracy, which ensures that the bearing bushings produced are of the highest quality. Furthermore, the process results in extremely tight tolerances, which allows for very precise bearings. Nevertheless, the process is not cheap and takes longer compared to other technologies.
The cold rolling of bearing bushings utilizes fluorocarbon rollers for optimal lubrication and surface finishing. The rollers should have a high coefficient of friction which will minimize slippage and maintain a consistent level of pressure on the surface during the rolling process. Furthermore, it should be able to dissipate heat quickly, resisting wear and tear on the die during the rolling process. Additionally, these lubricants help to ensure a smoother finish, with less burrs and smoother edges.
Precision cold rolling technology is used in the production of high-accuracy bearing bushings. The technology is well suited for mass production and provides the user with a reliable and precise outcome. Furthermore, it ensures that the bearing bushings are uniform in shape and size and of the highest quality. Although it is relatively expensive, the process is reliable and highly accurate, making it a great choice for bearing manufacturers.
