NACHI 1315 Self-aligning Ball Bearing: Versatile and Durable Support for Misalignment Compensation

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                                                                            

The NACHI 1315 self-aligning ball bearing is engineered to provide reliable performance in applications where misalignment is a common occurrence,

such as due to errors in mounting or shaft deflection.

This bearing type is designed to accommodate both static and dynamic misalignments, ensuring smooth operation under varying conditions.

1. Design and Construction:

   The NACHI 1315 features a unique design with two rows of balls, a common sphered raceway in the outer ring,

   and two deep uninterrupted raceway grooves in the inner ring.

   This construction allows the bearing to be insensitive to angular misalignment of the shaft relative to the housing.

2. Performance Characteristics:

• It accommodates both static and dynamic misalignment, making it suitable for applications with varying load directions and misalignments.

• The bearing excels in high-speed performance and is known for its low friction,

  which is beneficial for energy efficiency and reduced heat generation.

3. Load Carrying Capacity:

   While the NACHI 1315 is designed to handle light axial loads, it is crucial to note that for applications with higher axial load requirements,

   spherical roller bearings with similar self-aligning properties are recommended.

4. Cage Options:

• The bearing is fitted with either a pressed steel cage or a polyamide cage.

  The suffix "G" on the bearing number indicates the presence of a polyamide cage.

5. Temperature Considerations:

• Bearings with a polyamide cage should be used at operating temperatures below 120°C to ensure optimal performance and longevity.

6. Misalignment Tolerance:

   The maximum permissible misalignment angle for the NACHI 1315 is approximately 3° under general service conditions,

   providing a significant margin for error in installation and operation.

7. Applications:

   his self-aligning ball bearing is ideal for applications where misalignment is expected, such as in agricultural machinery,

   conveyor systems, and general industrial equipment where shaft deflection or installation errors might occur.
