Product Description

 

Zhejiang Judong Bearings Co., Ltd., established in [2016], is located in Zhejiang Province, China. We are a professional manufacturer and supplier of a wide range of bearing products. Our bearings are widely used in industries such as machinery manufacturing, automotive, electronics, home appliances, and industrial automation.

Self-aligning ball bearings are a type of rolling bearing, and their main aspects include the following:

Structural Features:
Self-aligning ball bearings typically consist of an inner ring, an outer ring, double rows of steel balls, and a cage.The outer ring raceway is spherical, giving the bearing its self-aligning capability.

Self-Aligning Function:

Self-aligning ball bearings can automatically adjust for misalignment between the shaft and housing, typically accommodating a misalignment angle of 1.5° to 3°.This feature allows the bearing to maintain normal operation even when the shaft is bent or there are installation errors.

 

Load Capacity:
Self-aligning ball bearings can withstand significant radial loads and certain axial loads.Suitable for applications involving combined loads.

Application Fields:

Widely used in industries such as motors, pumps, fans, transmission devices, agricultural machinery, and textile machinery.Suitable for high-speed operation and heavy-duty conditions in mechanical equipment.

Materials and Manufacturing:

Typically made from high-carbon chromium steel or stainless steel to ensure high strength and corrosion resistance.Precision manufacturing processes ensure high accuracy and long service life.

Sealing and Lubrication:

Offers various sealing options, such as contact seals and non-contact seals, to prevent contamination and lubricant leakage.Lubrication methods can be grease lubrication or oil lubrication, chosen based on specific application requirements.

Installation and Maintenance:

Designed for easy installation and disassembly, simplifying maintenance procedures.Regular maintenance and lubrication can extend the bearing's service life.

Standards and Specifications:

Self-aligning ball bearings comply with international standards (e.g., ISO, DIN), ensuring good interchangeability.Available in various sizes and specifications to meet different application needs.

Advantages:

Self-aligning capability reduces wear and failure caused by misalignment.Low friction improves mechanical efficiency.High load capacity and long service life reduce maintenance costs and downtime.

Precautions:

Ensure cleanliness and proper lubrication during installation and use.Avoid overload and impact loads to prevent bearing damage.

Due to their unique self-aligning function and high load capacity, self-aligning ball bearings play a crucial role in industrial applications, effectively enhancing the operational efficiency and reliability of mechanical equipment.

 

 

 

 

 

  

In the precise world of mechanical operation, the self-aligning ball bearing can be regarded as an outstanding operation safeguard expert! It has unparalleled self-aligning ability and can automatically correct the misalignment problem between the shaft and the bearing housing. Even if the deviation angle reaches 2° - 3°, it can easily cope with it, effectively reduce internal stress, and greatly extend the service life. Under high - speed operation, with extremely low rolling friction, it can achieve low - vibration and low - noise operation, making the equipment operate smoothly and efficiently. Moreover, its double - row ball structure endows it with excellent load - bearing capacity. It can withstand medium radial loads and certain axial loads, and easily cope with complex working conditions. In addition, it has low requirements for installation accuracy, is easy to maintain, and has an affordable cost. Choosing a self-aligning ball bearing means choosing efficient, stable, and long - lasting operation guarantee for your equipment!

Self-aligning ball bearings possess numerous unique selling points, making them stand out in various mechanical applications:

Exceptional Self-Aligning Performance:
The double-row ball structure and spherical raceway design of the inner ring provide self-aligning ball bearings with excellent self-aligning capabilities. They can automatically compensate for misalignment caused by shaft and housing misalignment, shaft deflection, and other factors, with a permissible misalignment angle of up to 2° - 3°. This feature significantly reduces internal stress concentration, prevents premature failure, and extends service life. They are particularly advantageous in equipment prone to misalignment, such as dryer rolls in paper machines and transmission shafts in mining machinery.

High-Speed Adaptability:
The spherical rolling elements reduce rolling friction, ensuring smooth operation. The special cage design ensures stable distribution and operation of the rolling elements even at high speeds, effectively reducing heat generation and wear. Suitable for high-speed motors, machine tool spindles, and other equipment requiring high rotational speeds, they maintain low vibration and noise levels, ensuring smooth and efficient operation.

Excellent Load-Carrying Capacity:
Although they are ball bearings, the double-row ball structure provides them with considerable radial load capacity, enabling them to withstand moderate radial loads. Some models can also handle certain axial loads, making them suitable for complex operating conditions with combined loads. In agricultural machinery and small construction equipment, where both radial forces from working components and axial forces from mechanical vibrations are present, self-aligning ball bearings perform reliably, ensuring normal equipment operation.

Easy Installation and Maintenance:
The self-aligning feature reduces the stringent requirements for installation precision, allowing for a certain degree of error during installation, which saves time and costs. Additionally, their simple structure and conventional lubrication methods make routine maintenance, inspection, and grease replacement straightforward. In case of failure, their high interchangeability and availability in the market facilitate quick replacement, minimizing equipment downtime and improving production efficiency.

Cost-Effectiveness:
Compared to some high-end and complex bearings, self-aligning ball bearings are relatively affordable. With their long service life and ease of maintenance, they reduce overall maintenance costs and equipment replacement frequency over the equipment's lifecycle, enhancing the return on investment. This makes them widely used in general industrial equipment where cost sensitivity and reliable bearing performance are critical.

These advantages make self-aligning ball bearings a preferred choice in a wide range of industrial applications, delivering both performance and economic benefits.
