Basic Parameters
UC: This part represents the basic type of insert bearing with spherical outside surface. The characteristic of insert bearings with spherical outside surface is that the outer ring is spherical. This structure enables the bearing to have the function of automatic alignment, which can compensate for the deflection and misalignment of the shaft within a certain extent, reducing the vibration and noise of the equipment.
T: In this model, "T" usually represents the type of bearing housing. Different letters correspond to different shapes or structures of bearing housings. This is to adapt to various installation environments and equipment requirements.
3: Generally, it is the size series code. The size series includes the size parameter ranges such as the inner diameter, outer diameter, and width of the bearing. The number "3" indicates that this bearing belongs to a specific size series. The size specifications of this series are formulated according to relevant standards. It determines the overall size and some basic geometric characteristics of the bearing, and is different from bearings of other size series in terms of size and load-carrying capacity.
19: It represents the inner diameter size code of the bearing. In this representation method, the inner diameter size is usually obtained through specific calculation rules. For UCT319, its inner diameter size is generally 95mm (inner diameter size = code × 5, that is, 19×5 = 95mm). This is a key parameter when selecting the shaft diameter that the bearing fits.

Structural Features
Spherical ball bearing body
- The core part of UCT319 is the spherical ball bearing. The outer ring of this kind of bearing is an outer spherical surface. This unique design endows it with excellent self-aligning ability. During the operation of the equipment, even if the shaft has slight deflection or misalignment, the spherical ball bearing can automatically adapt to this change, thereby effectively reducing the vibration and noise level of the equipment. This is an extremely important characteristic for equipment that requires high-precision operation or is sensitive to vibration.
Mounted design
- This bearing is equipped with a specific seat type, which provides stable and firm support for the bearing. The design of the seat has been carefully considered and can be well matched with the installation plane of various equipment to ensure the stable position of the bearing after installation. Moreover, this mounted design greatly simplifies the installation process. You can install UCT319 on the equipment relatively easily without complex installation tools or professional installation technology, which undoubtedly saves you time and labor costs.
Other detailed designs
- In the connection part between the bearing and the seat, as well as in the internal structure, there are some fine designs. For example, a good sealing structure can effectively prevent harmful substances such as dust, impurities and moisture from entering the inside of the bearing. This is crucial for prolonging the service life of the bearing and maintaining the stability of its performance. At the same time, the fit between the rolling elements and the raceway inside is also very precise, ensuring the smoothness and high efficiency of the bearing during operation.
Performance Advantages
Strong carrying capacity
- The UCT319 bearing has excellent carrying capacity. Whether it is radial load or axial load, it can effectively withstand. In some equipment that needs to bear heavy loads, such as industrial conveying equipment, auxiliary transmission parts of heavy machinery, etc., UCT319 can work reliably and provide solid guarantee for the normal operation of the equipment.
High durability and long service life
- Made of high-quality bearing steel material and through strict processing technology and heat treatment procedures. This makes the UCT319 bearing have high hardness and good wear resistance. During long-term use, it can resist various forms of wear and effectively extend the service life of the bearing. This not only reduces the number of equipment maintenance, reduces maintenance costs, but also can improve the overall operating efficiency of the equipment.
Adapt to various working conditions
- Due to its good sealing performance and robust structural design, the UCT319 bearing can adapt to many different working environments. Whether in a humid environment, a dusty workshop, or a chemical environment with certain corrosiveness, it can maintain stable performance and work normally. This adaptability makes it widely applicable in various industrial fields.

Product Application
Industrial transmission equipment field
- In various types of industrial transmission equipment such as belt conveyors and chain conveyors, the UCT319 bearing is often used to support the shaft of the transmission drum. In these devices, the bearing needs to bear various complex loads such as the weight of materials, the tension of the conveyor belt, and the vibration generated during the operation of the equipment. With its strong load-bearing capacity and good adaptability, the UCT319 can ensure the stable operation of transmission equipment and guarantee the efficient and accurate transportation of materials.
Heavy machinery auxiliary transmission part
- In some heavy machinery, such as large cranes, excavators, etc., the UCT319 bearing also plays an important role in the auxiliary transmission parts. These parts usually need to bear huge forces and complex movements. The UCT319 can provide stable support to ensure smooth power transmission of the machinery and improve the working efficiency and reliability of the machinery.
Other industrial equipment
- In industrial fans, pump equipment, simple machine tools and other equipment, the UCT319 bearing can also be well applied. For example, in industrial fans, it can support the fan shaft to ensure the stability of the fan when rotating at high speed; in pump equipment, it can bear the axial and radial forces generated by the rotation of the pump impeller to ensure the normal pumping or liquid transportation function of the pump.
