Product Features

• Excellent Load-bearing Performance, Adapted to Heavy-load Working Conditions: Adopting a single-row tapered roller structure, the rollers are in line contact with the raceways of the inner and outer rings, with a large contact area. It can efficiently bear both radial load and unidirectional axial load, with strong radial load-bearing capacity and precise axial positioning. It can easily cope with heavy loads, alternating loads and impact loads, perfectly adapting to medium and low-speed heavy-load scenarios, solving the pain point that ordinary bearings are easily damaged under heavy loads, and meeting the requirements of GB/T 273.1―2023/ ISO 355:2019 standards.
• Qualified Precision and Stable Operation: The bearing raceways are precision ground, with high surface smoothness. The rollers adopt a high-precision sorting process, with strong dimensional consistency. Combined with a precise contact angle (13°) design, the meshing gap is controllable. During operation, the vibration is small, the noise is low, there is no obvious abnormal noise, and the rotation precision is high, which can effectively improve the overall transmission precision of the equipment and adapt to scenarios with high requirements for operation stability.
• Separable Structure, Convenient Installation and Maintenance: The assembly composed of the inner ring, rollers and cage can be separated from the outer ring independently. This separable and interchangeable structural design facilitates the installation, disassembly and later maintenance of the bearing. There is no need to disassemble the entire transmission component of the equipment, which greatly saves maintenance man-hours, reduces maintenance costs, and facilitates the replacement of damaged components alone, improving the efficiency of equipment operation and maintenance.
• Excellent Material, Wear-resistant and Impact-resistant: The inner ring, outer ring and rollers are all made of high-strength bearing steel, which has undergone multiple heat treatment processes such as carburizing, quenching and tempering. It has high hardness, strong toughness, excellent surface wear resistance, corrosion resistance and impact resistance. It can effectively resist wear caused by heavy loads and vibrations, extend the service life of the bearing, and adapt to long-term stable operation under harsh working conditions, meeting the standards of high-quality bearing materials in the industry.
• Reasonable Cage Design and Strong Stability: Adopting a stamped steel cage, it has a solid structure and light weight, with good guidance and load-bearing capacity. It can effectively fix the position of the rollers, avoid offset and collision of the rollers during operation, reduce friction loss, and at the same time improve the overall structural stability of the bearing, prevent the cage from deformation and damage during high-speed operation, and ensure long-term stable transmission of the bearing.
• Wide Adaptability and Strong Versatility: Strictly designed according to standard sizes, it can be interchanged and used with bearings of the same specification. It is suitable for the transmission systems of various equipment such as heavy-duty trucks, engineering vehicle rear axles, reducers, cranes, and mining machinery. No additional modification is required, and the installation compatibility is strong, which can meet the supporting needs of different equipment and adapt to multi-scenario heavy-load operations.
