Basic Parameters

Starting number "2": In bearing models, the number "2" usually represents the category of cylindrical roller bearings or spherical roller bearings. For the model 2204K, it belongs to spherical roller bearings. The characteristic of spherical roller bearings is that they can automatically adjust the relative positions of the shaft and the housing, compensating for coaxiality errors caused by installation errors or shaft deflection.
"204" part: This set of numbers is used to represent the size of the bearing. Among them, "04" represents the inner diameter of the bearing. Generally, the inner diameter size is "04" multiplied by 5, so the inner diameter of this bearing is 20mm. The "2" in front is related to the size series. It is related to the ratio of sizes such as the outer diameter and width of the bearing. Different number combinations represent different size series.
"K" suffix: In bearing models, "K" usually has a specific meaning. Here, "K" represents a tapered bore bearing. The design of the tapered bore allows the bearing to obtain the appropriate radial clearance by adjusting the axial position during installation. This is very important for some equipment that requires precise control of clearance, such as some machinery with high requirements for rotational accuracy.

performance characteristics

Self-aligning performance

The outstanding performance of 2204K self-aligning roller bearing is its good self-aligning function. It can still maintain a good running state under certain shaft deflection or installation error. For example, in some long-shaft transmission equipment, due to the self-weight or force of the shaft, there may be a certain bending deformation. Using 2204K bearing can automatically adapt to this deformation, reduce local wear between the bearing and the shaft, and extend the service life of the bearing.

Bearing capacity

Self-aligning roller bearings generally have high radial bearing capacity, and 2204K is no exception. It can bear a large radial load, which makes it suitable for some equipment that bears heavy radial force. For example, on the support roller of the conveyor belt, it can well bear the weight of the conveyor belt and materials and ensure the stable rotation of the roller. At the same time, it also has a certain bearing capacity for a certain axial load and can work in a complex stress environment.

Installation flexibility (advantage of tapered hole)

Due to the tapered hole ("K" characteristic), there is greater flexibility when installing the 2204K bearing. The radial clearance of the bearing can be adjusted by axial displacement to achieve the best working state. This can better meet the installation and operation requirements for some precision equipment with strict clearance requirements, such as the spindle of precision machine tools.

Product Application

Agricultural machinery field
- Widely used in components such as rollers and conveyor belts of agricultural harvesters. During the working process of the harvester, the roller needs to bear the weight and impact force of crops. The high load-carrying capacity and self-aligning performance of the 2204K bearing can ensure the stable operation of the roller under complex working conditions and reduce failures.
Industrial conveying equipment field
- Used for supporting and driving rollers of various conveyor belts. On the material conveying line in factories, these rollers need to bear the weight of materials and the tension of conveyor belts for a long time. The 2204K bearing can adapt well to this working environment and ensure the efficient operation of conveying equipment.
Construction machinery field
- For example, in the rotating parts of some small construction machinery, like the support part of the mixing drum of a concrete mixer. During operation, the mixing drum will be subjected to the weight of concrete and the uneven force during mixing. The 2204K bearing can ensure the stable rotation of the mixing drum through its self-aligning performance and load-carrying capacity.
  - belts of agricultural harvesters
  - material conveying line
  - mixing drum
