Heavy Duty D-HB Series

Features and advantages of QIBR universal ball bearing D-HB series

1. Strong load-bearing capacity

QIBR universal ball bearing D-HB series has a large contact area and can withstand greater loads than ordinary bearings, making it suitable for heavy equipment and high-load environments.

2. High flexibility and freedom

QIBR universal ball bearing D-HB series is able to 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 D-HB 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. Self-aligning ability

QIBR universal ball bearing D-HB series has a certain self-aligning function. It can tolerate slight errors in the position of the shaft or outer ring during installation and reduce additional friction or loss caused by misalignment. This makes it particularly outstanding in some equipment with limited installation space.

The performance improvement and solutions of QIBR universal ball bearing D-HB 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 D-HB 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 parts at different angles to ensure the smooth transmission of ship power.
