Basic Parameters
Basic type identification
- UCFC: This is the specific type code for spherical outside surface ball bearings with square housings and eccentric bushings. This kind of bearing is composed of spherical outside surface ball bearings, square housings and eccentric bushings. The square housing is used to fix the bearing, and the eccentric bushing can adjust the center position of the bearing to a certain extent, facilitating installation and compensating for the installation error of the shaft.
Size series identification
- 2: In the UCFC series, the number "2" represents 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.
Inner diameter size identification"01": This part of the number represents the inner diameter size of the bearing. For UCFC201, its inner diameter size is usually 12mm. The inner diameter size is an important parameter when selecting a bearing, and it determines whether the bearing can fit the corresponding shaft diameter.
Structural Features
External spherical ball bearing The core of this bearing is the external spherical ball bearing. This design enables the bearing to self-align. During the operation of the equipment, even if the shaft has a certain degree of deflection or misalignment, the external spherical ball bearing can adapt well, effectively reducing the vibration and noise of the equipment and ensuring the smooth operation of the equipment.
Square base Equipped with a sturdy square base, the square base can provide stable and reliable support for the bearing. During installation, the square base can fit well with the installation plane of the equipment. Moreover, the installation method is relatively simple, which can easily fix the bearing on the equipment, saving installation time and labor costs.
Eccentric sleeve Having an eccentric sleeve is an important feature of UCFC201. The eccentric sleeve can adjust the center position of the bearing within a certain range. This has a good compensation effect for the installation error between the shaft and the seat hole that occurs during the installation process. In some equipment with high installation precision requirements, this design can facilitate installation and debugging.

Product Application
Load-bearing capacity
- UCFC201 has a certain load-bearing capacity and can withstand corresponding radial loads. Under suitable working conditions, it can ensure the normal operation of equipment and provide reliable support for the transmission parts of equipment.
Durability
- Usually made of high-quality bearing steel materials and undergoes precise processing and heat treatment processes, making it have relatively high hardness and wear resistance. During long-term operation, it can effectively resist wear, extend service life, and reduce the frequency and cost of equipment maintenance.
Installation convenience
- Due to the design of square seat and eccentric sleeve, this bearing has great convenience in the installation process. Whether it is for initial installation or replacing the bearing during equipment maintenance, the operation can be completed relatively easily, improving work efficiency.

Product Type
-
Light industry equipment: For example, household sewing machine, the support of its transmission shaft needs to bear a certain radial load and adapt to a certain speed. The size and load-carrying capacity of UCFC201 bearing can meet the requirements and ensure the stable operation of the transmission parts of the sewing machine during the sewing process. In small food processing equipment, such as small meat grinders, juicers, etc., UCFC201 bearing can provide reliable support for its rotating cutters or stirring shafts and adapt to the vibration and load generated by the equipment during food processing.
-
Agricultural machinery: For example, small water pump, which is often used in agricultural irrigation and rural domestic water supply and other scenarios. UCFC201 bearing can play a good supporting role between the motor and impeller of the water pump and ensure the stable operation of the water pump under different working conditions. In some small agricultural processing equipment, such as grain threshers, feed crushers, etc., UCFC201 bearing can also be used to support the transmission shaft and bear the impact and vibration of the equipment during operation.
-
Industrial equipment: In small conveyor, UCFC201 bearing can be used to support the roller shaft of the conveyor belt, bear the weight of the conveyor belt and materials and the tension during operation, and ensure the smooth transportation of materials. For some simple transmission devices, such as small reducers, the connection transmission parts between motors and working machinery, etc., UCFC201 bearing can adapt to its transmission requirements and provide stable support and good rotation performance.
-
Other equipment: It can also be applied to some transmission roller support parts in the insulating glass production line to ensure the smooth transmission of glass during the production process. In the inkjet printer, it is used to support the moving parts or transmission parts of the nozzle so that the inkjet printer can accurately print marks on products. In the sorting screen, it provides support for the vibration mechanism or transmission mechanism of the screen mesh, adapts to the vibration working condition of the equipment, and ensures the sorting effect.
