Orginal Imported NSK 2213 Self-aligning ball bearing

Self-aligning ball bearing features

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring.  

They are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.

It commodates static and dynamic misalignment, haa excellent high-speed performance, excellent light load performance and low friction.

Installation Methods and Usage Precautions for Self-aligning Ball Bearing                                                

The installation of self-aligning ball bearings is a crucial process that can significantly impact the performance and longevity of the bearing. 

Here is a detailed guide on the installation method and usage precautions for self-aligning ball bearings: 

Installation Method: 

Cleanliness is key: Before installation, ensure that the mounting surfaces are clean and free of any dirt, dust, or debris that could affect the bearing's performance. 

Proper handling: Handle the bearing with care to prevent any damage to the components. Avoid dropping or hitting the bearing during installation. 

Correct mounting: Ensure that the bearing is mounted in the correct orientation and position as per the manufacturer's instructions. 

Improper mounting can lead to misalignment and premature bearing failure. 

Use appropriate tools: Utilize the correct tools and equipment for mounting the bearing to prevent any damage to the bearing or surrounding components. 

Lubrication: Proper lubrication is essential for the smooth operation of the bearing. Make sure to lubricate the bearing as per the manufacturer's recommendations. 

Usage Precautions: 

Misalignment: Self-aligning ball bearings are designed to accommodate misalignment to a certain extent. 

However, excessive misalignment can lead to increased wear and reduced bearing life. 

Temperature: Monitor the operating temperature of the bearing to ensure it remains within the recommended range. 

High temperatures can accelerate wear and cause premature failure. 

Overloading: Avoid overloading the bearing beyond its rated capacity as it can lead to increased stress and potential failure. 

Contamination: Protect the bearing from contamination by sealing it properly and keeping the surrounding area clean. 

Regular maintenance: Perform regular inspections and maintenance checks to detect any issues early and prevent unexpected failures. 

In summary, the correct installation of self-aligning ball bearings, along with following usage precautions, 

is essential for ensuring optimal performance and longevity of the bearing. 

By adhering to these guidelines, you can maximize the efficiency and reliability of your machinery.

Introduction and Knowledge of Self-aligning Ball Bearing                                                                            

1. Product Overview:

The NSK 2213 Self-aligning ball bearing is a high-quality bearing designed for applications where aligning the shaft and housing is difficult or where the shaft may bend, such as in transmission shafts. This bearing is known for its ability to self-align and accommodate misalignment between the shaft and housing .

3. Design Features:

   The NSK 2213 bearing features a spherical raceway in the outer ring, allowing the bearing to self-align and compensate for misalignment between the shaft and housing. The center of curvature of the outer ring coincides with that of the bearing, allowing the inner ring, balls, and cage to rotate freely around the bearing center .

4. Performance Benefits:

• Misalignment Tolerance: The bearing can accommodate permissible dynamic misalignment of approximately 0.07 to 0.12 radians (4 to 7 degrees) under normal loads .

• Ideal for Difficult Mountings: Self-aligning ball bearings are suitable for applications where shaft bending occurs and where it is difficult to align the shaft and housing .

  
  

5. Applications:

   The NSK 2213 Self-aligning ball bearing is used in various applications including fluid machinery, lifting and transportation machinery, rotary tables, screw extruders, grinders, open-pit mining, mill headstock main shafts, trucks, centrifuges, rotary furnace guide wheels, electric locomotives, and material handling equipment .
