Features and advantages of QIBR universal ball bearing IK-B series
1. Square design
The QIBR universal ball bearing IK-B series flange has a square shape. Compared with the common round flange, the square flange is usually used in some special applications.
2. High flexibility and freedom
The QIBR universal ball bearing IK-B series can rotate in multiple directions and has high flexibility. It allows a certain angle change between the inner and outer rings to adapt to complex movement requirements. Due to this degree of freedom, it is particularly suitable for applications that require angle adjustment.
3. Low friction
The QIBR universal ball bearing IK-B series has lower friction resistance than traditional sliding bearings, which can effectively reduce energy loss and heat accumulation. Therefore, the universal ball bearing can maintain a high operating efficiency.
4. Save materials
The flange structure of the QIBR universal ball bearing IK-B series is connected to the bearing through a retaining ring, which is easy to process and saves materials.
The performance improvement and solutions of QIBR universal ball bearing IK-B series
1. Material Improvement
High-strength materials: Use higher-strength steel or alloy materials to improve the bearing's load-bearing capacity and wear resistance. Especially under high load and high temperature environments, high-quality materials can significantly increase the service life of bearings.
2. Optimization of lubrication technology
The use of high-performance lubricants or greases can reduce friction and reduce wear. For universal ball bearings operating under high temperature, high speed and harsh conditions, the selection of high-temperature lubricants and highly adaptable synthetic greases can help improve operating stability.
3. Design Optimization
Optimized design of rolling elements: Increase the number of rolling elements, or improve the load-bearing capacity and reduce the friction coefficient by improving the size and shape of the rolling elements, thereby improving the performance of the bearing.
4. Improved surface finish
Optimize the surface finish of the inner and outer rings and rolling elements of the bearing, reduce the friction coefficient, reduce energy loss during operation, and thus improve operating efficiency.
Main application areas of QIBR universal ball bearing IK-B series
1. Steering system
In the steering system of some models, universal ball bearings are used to connect the steering wheel and the wheel to allow the angle of the wheel to change during steering.
2. Agricultural machinery
Universal ball bearings in agricultural machinery are mainly used to connect tractors and agricultural machinery, especially when the power output of tractors is connected to other agricultural machinery, they can withstand large angle and torque changes to ensure the smoothness of power transmission.
3. Industrial machinery
In some high-angle conveyor belt systems, universal ball bearings can be used to connect different parts to meet the movement requirements in the production line.
4. Ship propulsion system
In the propulsion system of ships, universal ball bearings are used to connect shafts and mechanical components at different angles to ensure the smooth transmission of ship power.
