Basic Parameters
- UCF: This is the specific type code for spherical outside surface ball bearings with square housings and set screws. This kind of bearing usually consists of a spherical outside surface ball bearing and a square housing, with set screws on the housing for fixing the bearing.
- 2: In the UCF series, the number "2" indicates the size series of the bearing. Different size series correspond to different size parameters such as bearing inner diameter, outer diameter, and width. Size series "2" has its specific size specification range.
- 01: This part of the number indicates the inner diameter size of the bearing. For UCF201, its inner diameter size is usually 12mm. The inner diameter size is an important parameter when selecting a bearing, as it determines whether the bearing can fit the corresponding shaft diameter.
Structural Features
Outer spherical surface design
- The outer ring of the bearing is an outer spherical surface. This design enables it to self-align. During the operation of the equipment, even if the shaft has a certain degree of deflection or misalignment, UCF201 can adapt well, effectively reducing the vibration and noise of the equipment and ensuring the smooth operation of the equipment.
Square seat and set screw
- It is equipped with a square seat, which can provide stable support. There is a set screw on the square seat. Through the set screw, the bearing can be conveniently and quickly fixed on the installation surface of the equipment to ensure firm and accurate installation, greatly simplifying the installation process and also facilitating disassembly and maintenance.
Performance advantages
Bearing capacity
- UCF201 has good bearing capacity and can withstand a certain amount of radial load and axial load. Whether in light load or medium load working conditions, it can perform well and provide reliable guarantee for the normal operation of equipment.
Sealing performance
- Usually equipped with an effective sealing device, it can prevent dust, impurities and moisture from entering the bearing interior, avoid the loss of grease inside the bearing, prolong the service life of the bearing, and reduce the maintenance frequency and cost of equipment.

Product Application
-
Agricultural machinery: Such as small harvesters, planters, cultivators, etc. In these devices, the UCF201 bearing can withstand the vibration and impact loads generated during the operation of the equipment and adapt to the complex working environment in the field to ensure the stable operation of each rotating part of agricultural machinery.
-
Industrial fans: Including small ventilators, exhaust fans, etc. When the fan is running, the rotation of the impeller will generate radial and certain axial loads. The UCF201 bearing can provide reliable support for the fan shaft to ensure the normal operation of the fan and reduce vibration and noise.
-
Textile machinery: For example, looms, spinning machines, etc. Textile machinery usually needs to operate stably for a long time. The good sealing performance of the UCF201 bearing can prevent flying flowers, dust, etc. from entering the bearing interior and affecting its performance. At the same time, it can withstand the loads during the operation of textile machinery to ensure the smooth progress of textile processes.
-
Dyeing and printing equipment: In some equipment in the printing and dyeing industry, such as printing machines, dyeing machines, etc., it is also applied. These devices have certain requirements for the corrosion resistance and stability of bearings during operation. The UCF201 bearing can meet these requirements and adapt to the humid and chemical-containing environment of the printing and dyeing workshop.
-
Food processing machinery: Such as seasoning processing equipment, pill making machines, granulation and drying equipment, etc. The food processing industry has high requirements for hygiene and equipment stability. The UCF201 bearing has a simple structure and is easy to clean and maintain. It can work stably in food processing machinery and ensure the quality and efficiency of food processing.
-
Packaging machinery: For example, bag making machines, pharmaceutical packaging machinery, etc. Packaging machinery requires high-precision transmission and stable operation. The UCF201 bearing can provide accurate support for its transmission parts to ensure the accuracy and stability of the packaging process.
-
Woodworking machinery: Such as small sawing machines, sanding machines, etc. Woodworking machinery will generate large cutting forces and vibrations during work. The UCF201 bearing can withstand these forces and vibrations to ensure the stable rotation of parts such as the tool shaft of woodworking machinery and improve processing accuracy.
-
Conveying equipment: Including small belt conveyors, screw conveyors, etc. When conveying equipment transports materials, the bearing needs to bear the weight of the materials and the frictional force and other loads during the conveying process. The UCF201 bearing can adapt to these loads and ensure the normal operation of the conveying equipment.
Maintenance and care
Smooth lubrication
- UCF201 takes into account the convenience of lubrication in its design. When it is necessary to supplement or replace grease, it can be operated relatively conveniently to ensure that the bearing is always in a good lubrication state and further guarantee its service life.
Regular inspection
- It is recommended that customers regularly inspect the UCF201 bearing during the operation of the equipment to check for looseness, abnormal wear and other conditions. Timely handling if problems are found can avoid losses such as equipment shutdown caused by bearing failures.
