KOYO 2219 Self-aligning ball bearing high speed

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                                                                            

KOYO 2219 Self-aligning ball bearing is recognized for its high-speed capabilities and is designed to handle misalignments between the shaft and housing.

• Product Information: The KOYO 2219 is a self-aligning ball bearing with a spherical outer ring raceway that matches the bearing center, allowing for rotation even when the inner ring, balls, and cage are tilted with respect to the outer ring to some extent. This feature makes it suitable for applications involving misalignment between the axis and housing centers, or axis deflection

• Specifications: The bearing has an inner diameter (d) of 95 mm, an outer diameter (D) of 170 mm, and a width (B) of 43 mm. The minimum radius (r) is 2.1 mm, and the bearing has a dynamic load rating (Cr) of 288 kN and a static load rating (C0r) of 298 kN. The fatigue load limit (Cu) is 42.9 kN. For speed, the bearing has a limiting speed of 3300 rpm when grease lubricated and 4400 rpm when oil lubricated

• Mounting Dimensions: The bearing has specific mounting dimensions, with a minimum inner diameter (da) and a maximum outer diameter (Da) of 159 mm. The bearing also has specific dimensions for db (inner ring) and dc (outer ring), which are essential for proper installation

• Applications: The KOYO 2219 is used in a variety of industrial fields, including construction, transportation, and agricultural machinery, where high-speed rotation and misalignment compensation are required .

• Technical Calculations: KOYO provides technical calculations for this product, including bearing service life, operating clearance, grease feeding interval, passing frequency, and elastic displacement .

• Mass: The mass of the KOYO 2219 bearing is 3.98 kg, which is an important consideration for handling and installation

• High-Speed Performance: The KOYO 2219 is particularly noted for its high-speed capabilities, making it suitable for applications requiring high rotational speeds and low friction .

• Benefits: The 2219-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

• Usage: This bearing is suitable for applications where misalignment can arise from errors in mounting or shaft deflection, such as in automotive power steering systems, agricultural machinery, textile machines, and conveyor systems
