PSL012-302 four point contact high-precision bearing produced by Luoyang HUANA Precision Bearing Technology Co., Ltd. has a split outer ring structure.The four point contact outer ring two hemisphere bearing is a specially designed bearing that combines multi-point contact and split outer ring structure, suitable for complex loads and high-performance requirements. Here is a detailed analysis of it:PSL012-302 Bearing * * Structural Features**1. Four point contact design:-Each rolling element (usually a steel ball) forms four contact points with the inner and outer raceway, usually achieved through elliptical grooves or special raceway shapes.-Allowing simultaneous bearing of bidirectional axial loads, radial loads, and moment loads, especially suitable for applications with high axial loads or frequent directional changes.2. * * Split outer circle (two hemispheres) * *:-The outer ring is composed of two hemispherical components, which are easy to install and maintain, especially in situations where space is limited or frequent disassembly is required.-Split design may be connected by bolts or snap rings, ensuring alignment and fastening to avoid stress concentration.PSL012-302 Bearing * * Performance Advantages**-High load-bearing capacity: Four point contact disperses loads, enhancing axial and radial load capacity.-* * Bi directional force * *: Suitable for equipment that needs to withstand positive and negative axial forces, such as gearboxes and slewing supports.-* * Self centering ability * *: Some designs allow for compensation of certain angular deviations, adapting to the alignment error between the shaft and the seat.PSL012-302 Bearing * * Application Fields**-Heavy Machinery: The slewing mechanism of cranes and excavators.-Wind power equipment: Yaw and pitch systems are designed to handle multi-directional wind.-Aerospace: high-precision and high load components such as landing gear and servo.-Industrial robots require flexible load-bearing of complex forces at their joints.PSL012-302 Bearing * * Design Considerations**-Materials and processes: High strength alloy steel or ceramics are used, and their wear resistance is enhanced through carburizing and quenching treatment.-Lubrication and Sealing: Efficient lubrication (such as grease lubrication or oil mist) and sealing design are required to prevent contamination at the separation point.-* * Pre tightening and clearance * *: Precise control to optimize stiffness and lifespan, split structure may provide adjustment convenience.PSL012-302 Bearing * * Potential Challenges**-Installation accuracy: The split outer ring requires high centering, and misalignment can easily lead to wear.-Structural strength: The split connection needs to be strengthened to avoid becoming a weak point.-Friction and heat generation: Multi point contact may increase friction, and effective heat dissipation measures are needed.PSL012-302 Bearing * * Summary**This bearing balances high load capacity and installation convenience through innovative four point contact and split outer ring design, making it an ideal choice for heavy-duty and multi-directional stress scenarios. Proper selection, installation, and maintenance are key.
