Features and advantages of QIBR universal ball bearing SP series
1. Multi-directional load-bearing capacity
The biggest feature of QIBR universal ball bearing SP series is that it can withstand loads from different directions, especially radial and axial loads. This bearing can provide stable support at multiple angles and is suitable for equipment that needs to withstand complex mechanical effects.
2. High flexibility and freedom
QIBR universal ball bearing SP 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
QIBR universal ball bearing SP series has lower friction resistance than traditional sliding bearings, which can effectively reduce energy loss and heat accumulation. Therefore, universal ball bearings can maintain high operating efficiency.
4. High load-bearing capacity
QIBR universal ball bearing SP series is usually designed with multiple rolling elements that can roll between the inner and outer rings of the bearing to disperse the load pressure. In this way, it can still maintain smooth operation under higher load conditions and has a strong load-bearing capacity.
The performance improvement and solutions of QIBR universal ball bearing SP 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, and reduce energy loss during operation, thereby improving operating efficiency.
Main application areas of QIBR universal ball bearing SP 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 the steering process.
2. Agricultural machinery
Universal ball bearings in agricultural machinery are mainly used to connect tractors and agricultural machinery, especially when the power output of the tractor is connected to other agricultural machinery, it can withstand large angle and torque changes to ensure the stability 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. Automation equipment
Many automated machines and devices require universal ball bearings to ensure stable power transmission between parts.
