High Turning Performance Self Aligning Ball Bearing Needle Bearing for Steel Industry 

Product Description

Self Aligning Ball Bearings

Self aligning ball bearings have 2 rows of balls, a common sphered raceway in the outer ring and 2 deep uninterrupted raceway grooves in the inner ring. Self aligning ball bearings are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection or housing deformations. Self aligning ball bearings are suitable for applications where the shaft relative to the housing bore is prone to angular misalignments. Under normal loads, depending on the dimensional series, the maximum permissible angular misalignment is approximately 2° to 4°. These bearings are available in open and sealed versions and inner rings with a cylindrical or tapered bore.

Can you describe the various types of seals and shields used with steel ball bearings for contamination prevention?

Steel ball bearings are often equipped with seals and shields to prevent contamination from entering the bearing and affecting its performance. These protective components act as barriers, keeping out solid particles, liquids, and other contaminants that could lead to premature wear, corrosion, or damage. Here are some of the common types of seals and shields used with steel ball bearings for contamination prevention:

1. Rubber Seals:

Rubber seals, also known as contact seals or lip seals, are widely used to provide effective contamination protection for steel ball bearings. These seals are typically made of synthetic rubber materials, such as nitrile rubber (NBR) or fluoroelastomer (FKM). Rubber seals are designed to have direct contact with the bearing inner and outer rings, creating a physical barrier against contaminants. They form a tight seal around the rotating inner ring, preventing the ingress of dust, dirt, moisture, and other particles. Rubber seals offer good sealing performance and are effective in most operating conditions.

2. Metal Shields:

Metal shields, also known as non-contact shields or metal covers, are metallic components that provide contamination protection for steel ball bearings. These shields are typically made of steel or stainless steel and feature a circular shape that covers the bearing opening. Metal shields do not come into direct contact with the bearing rings but provide a physical barrier against larger particles and debris. They are designed with a small gap between the shield and the inner ring, allowing for minimal friction and unrestricted rotation. Metal shields are commonly used in applications where low torque and high-speed operation are required.

3. Felt Seals:

Felt seals are simple and cost-effective sealing components used with steel ball bearings. These seals are made from compressed or impregnated felt material. Felt seals can be installed in the outer ring of the bearing to create a barrier against dust and small particles. While they provide limited protection against liquid contaminants, felt seals are effective in preventing the ingress of solid particles. Felt seals are commonly used in applications where moderate contamination protection is required, and the operating conditions are not excessively demanding.

4. Labyrinth Seals:

Labyrinth seals are non-contact seals that use a complex, tortuous path to prevent contaminants from entering the bearing. They consist of multiple interlocking grooves or ridges on the bearing housing and the seal itself. The labyrinth design creates a series of barriers that impede the entry of particles and fluids. Labyrinth seals are effective in providing contamination protection in applications where high-speed rotation, heavy contamination, or exposure to liquids is a concern. They offer low friction and can withstand challenging operating conditions.

5. Combination Seals and Shields:

In some cases, steel ball bearings may be equipped with combination seals and shields to provide enhanced contamination protection. These hybrid sealing arrangements combine the benefits of both seals and shields to provide a higher level of defense against contaminants. For example, a bearing may feature a rubber seal on one side to provide excellent sealing performance, while having a metal shield on the other side to allow for lower friction and higher speed operation. Combination seals and shields offer versatility and can be tailored to specific application requirements.

6. Customized Sealing Solutions:

Depending on the specific application and operating conditions, customized sealing solutions may be developed for steel ball bearings. These solutions can involve the use of specialized materials, unique designs, or additional protective features. Customized seals and shields are typically designed to address specific challenges, such as extreme temperatures, aggressive chemicals, high-pressure environments, or stringent cleanliness requirements. Manufacturers and bearing suppliers can work with customers to develop tailored sealing solutions that provide optimal contamination prevention for their specific applications.

Seals and shields play a critical role in preventing contamination and maintaining the performance and service life of steel ball bearings. The choice of the appropriate seal or shield depends on factors such as the operating environment, speed, load, and level of contamination risk. By effectively preventing the ingress of contaminants, these protective components help ensure the reliable and efficient operation of machinery and equipment.
