Features and advantages of QIBR insert bearings with grub screws (metric shafts)
QIBR insert bearings with grub screws (metric shafts) solve several key problems in various fields, particularly in the following aspects:
1. Self-aligning ability
The insert bearing has a self-aligning function. It consists of an inner ring, outer ring, rolling elements, and cage. The spherical shape of the outer ring allows the bearing to accommodate certain axial and radial errors. Even when the shaft is not perfectly aligned during installation, the bearing can still function properly, reducing damage caused by installation errors.
2. High load capacity
Insert bearings can typically bear large radial loads and certain axial loads, making them suitable for heavy-duty machinery.
3. Durability and reliability
Due to their structural characteristics, insert bearings are wear-resistant and impact-resistant, and show strong reliability in unfavorable working conditions (such as dusty or humid environments).
4. Easy fastening
The countersunk screw design makes both fastening and disassembly more convenient. This design is particularly useful in applications that require regular maintenance and replacement.
Performance improvements and solutions for QIBR insert bearings with grub screws (metric shafts)
1. Material improvement
High-performance materials: Using high-strength, high-wear-resistant materials such as ceramics, advanced alloy steels, and stainless steel can significantly improve the durability and load-bearing capacity of insert bearings.
Surface treatment: Surface treatments like carburizing, nitriding, chrome plating, and hardening can enhance the bearing's wear resistance, corrosion resistance, and fatigue strength.
2. Precision improvement
High-precision manufacturing: Advanced processing technologies such as CNC machining and precision grinding improve the bearing’s processing accuracy, leading to smoother operation and lower noise.
High-precision fit: Improving the fit accuracy between the inner and outer rings of the insert bearing ensures the flexibility and stability of the bearing's rotation, reducing friction and wear.
3. Sealing performance improvement
Efficient sealing: More efficient sealing structures, such as double-lip seals or skeleton seals, can effectively prevent dust and dirt from entering the bearing, reducing contamination, and extending its service life.
Sealing materials: Using heat-resistant, wear-resistant, and corrosion-resistant sealing materials ensures bearing reliability in harsh environments.
4. Load capacity enhancement
Optimized design: By optimizing the geometry of insert bearings, such as increasing the contact area and adopting a stronger outer ring structure, their load-bearing capacity is improved, enhancing the bearing's ability to withstand loads.
Main application areas of QIBR insert bearings with grub screws (metric shafts)
1. Agricultural machinery
Insert bearings are commonly used in agricultural machinery such as tractors, seeders, harvesters, etc. These machines are often subject to high loads and may experience axial or radial misalignment, making the self-aligning feature of insert bearings very suitable for this environment.
2. Construction machinery
Insert bearings are widely used in construction machinery such as cranes, excavators, and concrete mixers. Construction machinery often operates in high-load and high-impact environments, and the high load capacity and self-aligning features of insert bearings help equipment run more smoothly.
3. Automotive industry
In automotive suspension systems, wheel axles, and steering components, insert bearings are widely used. Insert bearings can withstand reverse impact forces and lateral forces from the tires and suspension systems, making them ideal for automotive applications.
4. Conveying equipment
Insert bearings are widely used in various conveying equipment such as conveyor belts, belt conveyors, and roller conveyors. Insert bearings can adapt to load variations in conveying equipment and axial misalignment caused by long-term operation of the equipment.
