Unique Structural Designs of Bantalan Bola Kontak Sudut

• Double Row Centripetal Thrust Structure: Xingtai weizi bearing co., ltd.'s bantalan bola kontak sudut feature a double row centripetal thrust bearing structure in some models. This design matches the raceway surfaces of the outer rings of two single - row centripetal thrust ball bearings, integrating both the inner and outer rings into one unit. This unique structure endows the bearing with the capability to withstand thrust loads in two directions. In CNC machine spindles, where forces can act from multiple directions during complex machining operations, this dual - direction thrust load - handling ability ensures stable spindle operation and accurate machining results.
•  
• Four - Point Contact Ball Bearing Design: The four - point contact ball bearing, another type of angular contact bearingoffered by Xingtai weizi bearing co., ltd., is a single - row radial thrust bearing. It has an inner ring separated into two parts in a vertical plane relative to the central axis, with the inner and outer rings also separated. This design enables the bearing to handle loads in two directions. In CNC applications, this design allows for better distribution of forces, reducing stress concentrations and enhancing the overall durability of the bearing. It is especially beneficial when the spindle is subjected to varying radial and axial loads during different machining processes.
•  
• Copper Alloy Cutting Cages:Generally, Xingtai weizi bearing co., ltd.'s bantalan bola kontak sudut utilize copper alloy cutting cages. These cages play a crucial role in guiding and spacing the balls within the bearing. The use of copper alloy provides a good balance of strength, durability, and lightweight properties. In high - speed CNC machine spindles, the lightweight yet robust cages reduce the inertia of the rotating assembly, enabling faster acceleration and deceleration of the spindle. Additionally, the copper alloy cages can withstand the high - temperature and high - stress environments within the spindle, ensuring long - term reliable operation.

Load - Handling Capabilities of Angular Contact Bearings

• Simultaneous Radial and Axial Load Handling: Angular contact bearingsfrom Xingtai weizi bearing co., ltd. are designed to carry both radial and axial loads simultaneously. This is a critical feature for CNC machine spindles, as they often experience a combination of forces during machining. The ability to handle these loads concurrently ensures that the spindle maintains its precise position, reducing vibrations and improving the surface finish of the machined parts. Whether it's the radial forces generated by the cutting tool engagement or the axial forces from feed motions, these bearings can effectively manage the loads, enhancing the overall machining accuracy and efficiency.
•  
• Contact Angle and Axial Load Capacity: The contact angle of angular bearingis a key factor in determining its load - handling capabilities. Xingtai weizi bearing co., ltd.'s bantalan bola kontak sudut are available with contact angles of 15°, 25°, 26°, 36°, and 40°. The larger the contact angle, the greater the bearing's capacity to handle axial loads. In CNC machine spindles, where precise control of axial movement is essential for accurate machining, choosing the right contact angle based on the application requirements is crucial. For example, in high - precision milling operations that involve significant axial forces, bearings with a larger contact angle can provide the necessary support and stability.
•  
• Duplex Arrangement for Enhanced Performance: When used to carry radial loads, bantalan bola kontak suduttypically generate additional axial thrust. To address this, Xingtai weizi bearing co., ltd. recommends a duplex arrangement for these bearings in CNC machine spindles. In a duplex arrangement, the bearings can be preloaded or have their axial clearance adjusted. Preloading helps to eliminate play between the bearing components, increasing the stiffness of the spindle. This enhanced stiffness reduces deflection under load, resulting in improved machining accuracy and better surface finish. Adjusting the axial clearance allows for fine - tuning of the bearing's performance based on the specific operating conditions of the spindle.
