Mining machinery Construction equipment SKF 2312 Self-aligning ball bearings

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                                                           

SKF 2312 Self-aligning ball bearings are designed to handle angular misalignment between the shaft and the housing,

which can be caused by shaft deflection or other factors.

SKF 2312 Self-aligning Ball Bearings

• Design Features: SKF 2312 bearings are double-row, self-aligning ball bearings with a tapered bore.

  They consist of two rows of balls, a common sphered raceway in the outer ring, and two deep uninterrupted raceway grooves in the inner ring.

  This design allows the bearing to accommodate both static and dynamic misalignment without compromising performance.

• Mounting Ease: The tapered bore of the 2312 K model facilitates easy mounting via adapter sleeves or withdrawal sleeves,

  making installation more convenient.

• Performance: These bearings offer excellent high-speed performance, are well-suited for light load applications, and feature low friction,

  which contributes to their longevity and efficiency.

• Applications: SKF 2312 bearings are versatile and can be used in a variety of applications where misalignment is expected,

  such as in automotive power steering systems, agricultural machinery, textile machines, conveyor systems, and heavy-duty mining equipment.

• Technical Specifications: The bearing has an inner diameter of 60mm, an outer diameter of 130mm, and a width of 46mm.

  It is equipped with a steel cage and operates with normal radial internal clearance.

• Load Ratings: The dynamic load rating is 87.1 kN, the static load rating is 28.5 kN, and the fatigue load rating is 1.46 kN.

  The reference speed rating is 9500 r/min, and the limiting speed rating is 7000 r/min.

• Benefits: The 2312 K bearing provides benefits such as misalignment adaptability, high-speed efficiency, longevity and low maintenance,

  optimized performance under light loads, and noise and vibration reduction.

These bearings are an excellent choice for applications requiring high radial loads and where misalignment is a common issue,

ensuring smooth operation and reduced stress on the bearing components.
