Tapered roller bearing is a kind of radial thrust rolling bearing with tapered rolling elements as the core, which belongs to separate bearing. Its inner and outer rings are designed with matched tapered raceways. With unique structural design, it can efficiently bear radial and axial combined load, adapt to various heavy load and high-precision working conditions, and widely used in industrial production and various mechanical equipment fields. It is the core transmission component under heavy load scenes. It has strong bearing capacity, accurate positioning, wide adaptability and other obvious advantages, providing reliable support for stable operation of equipment.

Structural features

The core structure of the tapered roller bearing is composed of four key parts: inner ring, outer ring, tapered roller and cage. Some models can be equipped with seals according to the working conditions. The components work together, taking into account the performance and practicability:

-Inner and outer rings: all are designed with tapered raceways, and the raceway angle can be accurately measured to effectively convert the radial load into axial load, so as to achieve two-way force balance; The inner and outer rings can be separated to facilitate separate installation, disassembly and maintenance, greatly improving the equipment maintenance efficiency, and the outer ring and inner ring components of the same model can achieve international interchangeability and meet the requirements of standardized assembly.

-Tapered roller: processed by precision forming process, perfectly fit with raceway, with uniform contact area, which can effectively disperse load, reduce local stress concentration, reduce operating friction coefficient, and take high rotating speed and stability into consideration; Some heavy duty models further improve bearing capacity and impact resistance by increasing roller diameter and number of rollers.

-Holder: It is made of high-quality materials (such as capping retainer). Its function is to evenly separate tapered rollers, prevent friction and collision between rollers, ensure smooth rolling of rollers, reduce wear, extend the overall service life of bearing and adapt to different rotational speeds and load requirements.

-Optional seals: For severe working conditions, seals made of fluorine rubber and other materials can be equipped. The new seal lip design can effectively prevent dust, impurities and moisture intrusion, reduce grease loss, reduce internal water immersion, adapt to dusty, wet, high temperature and other complex working environment, and further extend the service life of the bearing.

Product Classification

-Single-row tapered roller bearing: it is the most commonly used type, which can bear radial load and axial load in single direction. The raceway cone angle is usually 10 ° - 19 °. The large-cone angle type (cone angle 25 ° - 29 °, rear code plus B) can bear larger axial load. During installation, the radial and axial clearance can be adjusted. It is widely used in various general mechanical equipment.

-Double-row tapered roller bearing: the outer ring (or inner ring) is an integral structure, and the small end faces of the two inner rings (or outer rings) are close to each other. The clearance and pre-interference are adjusted by the spacer ring, which can bear the bidirectional axial load and radial heavy load. It is suitable for the gear box, lifting equipment, steel rolling machine and other scenes.

-Four-row tapered roller bearing: designed with four outer rings, it can realize uniform load distribution and bear radial and axial combined load under low and medium speed. It is almost exclusively used for work roll application of heavy machinery such as large cold rolling mill and hot rolling mill. Some sealing types are suitable for severe working conditions such as rolling mill roll neck, with high sealing performance and large load capacity.

-Matched tapered roller bearing: including face-to-face, back-to-back and series matching modes, which can bear bidirectional axial load, have high bearing capacity and extremely high rigidity, and adapt to precision equipment and heavy machinery with extremely high rigidity and stability requirements.
