Luoyang HUANA Precision Bearing Technology Co., Ltd. produced PSL012-302、PSL012-304、PSL012-303、PSL012-301、PSL012-312、PSL012-305、PSL012-300 four point contact high-precision bearing 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.

The bearing models BB1-9938 | BB1-9928 | BB1-9925B with flange four point contact ball bearings produced by Luoyang HUANA Precision Bearing Technology Co., Ltd. are used in industries such as cutting. The bearings in this series are subjected to large radial forces and dust, so a double rubber cover sealing process is adopted. Due to the high cutting speed, special designs are made for the retainer and other processes. To meet the working conditions, the ring is made of advantageous bearing steel, which is quenched as a whole with a quenching hardness of around HRC60. The hardness of the bearing is improved through quenching process, thereby enhancing its wear resistance.This product is a special structure that can simultaneously withstand large axial loads, radial loads, overturning moments, and other comprehensive loads, integrating multiple functions such as support, rotation, transmission, and fixation.The product has mounting holes on the outer ring, which are fixed to the equipment with bolts. Even with high-speed rotation and excessive radial force, the bearing can operate smoothly.BB1-9938 | BB1-9928 | BB1-9925B bearing products have been supplied to customers for a long time and have received unanimous praise from customers. Our company's research and development of this series of products has a short production cycle and strict production processes in accordance with international standards.

The F017062104 (SR10/360Y) slewing bearing produced by Luoyang HUANA Precision Bearing Technology Co., Ltd. has an inner diameter with a V-shaped positioning groove. The groove size is designed and developed by our company specifically for users. Although other industries have similar sizes, it does not meet the installation requirements of customers. When installing, it should be used in a fixed position corresponding to the equipment. The bearing size is 256 * 360 * 19.05MM, which belongs to thin-walled turntable bearings. In addition to strict positioning requirements, the use of bearings also results in large axial and radial loads. The bearings are made of special high-speed bearing steel material, and the internal steel balls and their retainers are also processed and designed through special processes. Effectively meet the special requirements of user usage conditions.F017062104 (SR10/360Y) has significant requirements for the rigidity of the product used. Our company has produced this type of product multiple times and has rich production experience. Our products have received unanimous praise from customers.
