Double row tapered roller bearings are a new type of rolling bearing. Compared to traditional tapered roller bearings, they have stronger performance and can withstand larger radial and axial loads. Due to the characteristics of double row tapered roller bearings, they have the following advantages compared to other types of bearings:
1. Higher load-bearing capacity: The internal structure of double row tapered roller bearings is composed of two identical tapered roller bearings, each of which is independent and capable of withstanding radial and axial loads independently. Therefore, compared to single row tapered roller bearings, double row tapered roller bearings have higher load-bearing capacity.
2. Higher rotational accuracy: Double row tapered roller bearings have higher rotational accuracy because their internal structure can avoid friction and heat generation, reducing resistance during rotation. Therefore, their rotational accuracy is higher than that of single row tapered roller bearings.
3. Longer service life: The design of double row tapered roller bearings is more advanced, and the materials and manufacturing processes used are aimed at improving their service life. In addition, double row tapered roller bearings also have good self-lubricating performance, which can reduce friction and heat generation, thereby extending their service life.
4. Better stability: The internal structure of double row tapered roller bearings is relatively stable, therefore, their stability is higher than that of single row tapered roller bearings. Especially under special working conditions such as high speed, high temperature, high load, and strong impact, double row tapered roller bearings still perform well, demonstrating their excellent stability.
Overall, compared to traditional tapered roller bearings, double row tapered roller bearings have higher load-bearing capacity, higher rotational accuracy, longer service life, and better stability. Therefore, they have been widely used in many industries.
