Product Description

10PCS Ball Bearing 6700zz 10X15X4mm Metal Shielded Deep Groo
Deep groove ball bearing consists of an outer ring, an inner ring, a group of steel balls and a group of cages. There are 2 types of deep groove ball bearings: single row and double row. Deep groove ball structure is also divided into seal and open structure. The open type means that the bearing has no sealing structure. The sealed deep groove ball is divided into dust-proof seal and oil-proof seal. The dust-proof seal cover is made of steel plate, which only serves as a simple way to prevent dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent grease overflow in the bearing.

Are shielded bearings suitable for high-speed applications?

Yes, shielded bearings can be suitable for high-speed applications, but their suitability depends on various factors such as the bearing design, materials, and operating conditions. Here’s a detailed explanation of the suitability of shielded bearings for high-speed applications:

Shielded bearings are designed to accommodate a wide range of operating speeds, including high-speed applications. However, it’s important to consider the following factors when determining the suitability of shielded bearings for high-speed use:

  1. Bearing design: The design of the shielded bearing plays a significant role in its ability to handle high speeds. Factors such as the type of rolling elements (balls or rollers), cage design, and internal clearances affect the bearing’s ability to minimize friction, reduce heat generation, and maintain stability at high speeds. Manufacturers provide specific speed ratings for their shielded bearings, indicating the maximum recommended rotational speed. It’s important to select a shielded bearing with a speed rating that exceeds or matches the operating speed requirements of the application.
  2. Bearing materials: The materials used in shielded bearings can impact their performance at high speeds. High-quality materials with excellent hardness, dimensional stability, and low friction coefficients are preferred for high-speed applications. Common bearing materials include steel, stainless steel, and ceramics. Ceramic bearings, in particular, are known for their high-speed capabilities due to their low density and superior hardness. Consider choosing a bearing material that is well-suited for the anticipated speed and operating conditions.
  3. Lubrication: Proper lubrication is critical for high-speed applications. Lubrication helps reduce friction, dissipate heat, and minimize wear between the bearing components. It’s important to select a lubricant that is specifically recommended for high-speed applications and provides adequate lubrication under the anticipated speed and temperature conditions. The lubrication quantity and method should also be optimized to ensure sufficient lubrication without causing excessive drag or overheating.
  4. Temperature control: High-speed applications can generate significant heat due to increased friction. Adequate temperature control measures, such as proper ventilation, cooling systems, or selecting bearings with heat-resistant materials, may be necessary to prevent excessive temperature rise and potential bearing damage or failure.
  5. Application-specific considerations: High-speed applications may involve additional factors that need to be considered. For example, the presence of external forces, vibration, or misalignments can affect the performance and stability of the shielded bearing at high speeds. It’s important to evaluate these factors and choose a bearing design that can withstand the specific demands of the application.

By considering these factors and selecting shielded bearings with suitable designs, materials, lubrication, and temperature control measures, you can ensure their reliability and performance in high-speed applications.

How do shielded bearings handle radial and axial loads?

Shielded bearings are designed to handle both radial and axial loads, although the specific load capacities may vary depending on the bearing design and size. Here’s a detailed explanation of how shielded bearings handle radial and axial loads:

Radial Loads: Radial loads are forces that act perpendicular to the bearing’s axis, causing it to rotate. Shielded bearings can handle radial loads by distributing the load evenly across the rolling elements, races, and the bearing’s internal structure. The rolling elements, typically balls or rollers, transmit the load from the outer race to the inner race. The races are the ring-like structures that contain the rolling elements and guide their movement. The distribution of the load helps prevent localized stress and ensures that the bearing can support the applied radial load without excessive deformation or premature failure.

The load-carrying capacity of a shielded bearing under radial loads depends on various factors, such as the bearing’s size, design, materials, and the number and size of the rolling elements. Manufacturers provide load ratings for shielded bearings, which indicate the maximum radial load that the bearing can sustain under specific operating conditions. It’s crucial to consider these load ratings and ensure that the applied radial load falls within the recommended limits to prevent bearing failure.

Axial Loads: Axial loads are forces that act parallel to the bearing’s axis, causing it to move in the axial direction. Shielded bearings can handle axial loads to some extent, but their capacity to resist axial loads is generally lower compared to their radial load capacity. The ability of a shielded bearing to handle axial loads depends on its design, including the type of rolling elements and the presence of additional features such as cages or thrust washers.

In applications with predominantly axial loads, specialized bearing designs like thrust bearings or angular contact bearings may be more suitable. These bearings are specifically engineered to handle higher axial loads and provide enhanced axial load-carrying capabilities.

It’s important to note that the load-carrying capacities of shielded bearings may also be influenced by factors such as the speed of rotation, operating temperature, lubrication, and the presence of any external forces or moments acting on the bearing. Therefore, it’s crucial to consult the manufacturer’s specifications and guidelines to determine the appropriate bearing type and size for a given load application.

By understanding the load requirements of your application and selecting the appropriate shielded bearing with sufficient load capacity, you can ensure reliable and efficient operation while minimizing the risk of premature failure or damage to the bearing.

How does a shielded bearing differ from a sealed bearing?

A shielded bearing and a sealed bearing are two different types of rolling bearings that offer varying levels of protection against contaminants and retention of lubrication. Here’s a detailed explanation of the differences between a shielded bearing and a sealed bearing:

Shielded Bearing:

A shielded bearing incorporates shields made of metal (typically steel or stainless steel) to cover the rolling elements and raceways of the bearing. The shields act as a physical barrier against solid contaminants, such as dust, dirt, or debris, preventing them from entering the bearing. The primary functions of the shields are to protect the internal components from contamination and retain the lubricating grease or oil within the bearing.

Shielded bearings provide moderate protection against contaminants, but they are not completely sealed. They allow for some exchange of air and limited penetration of fine particles. Shielded bearings are suitable for applications where the risk of contamination is moderate and where regular maintenance and relubrication can be performed. They are commonly designated with the suffix “Z” or “ZZ” in the bearing model or part number.

Sealed Bearing:

A sealed bearing, on the other hand, incorporates sealing elements made of synthetic rubber or other materials to provide a more effective barrier against contaminants. The seals are designed to completely enclose the internal components of the bearing and prevent the ingress of solid and liquid contaminants, such as dust, dirt, water, or chemicals.

Sealed bearings offer a higher level of protection and are suitable for applications where the risk of contamination is high or where maintenance and relubrication are more challenging. The seals help to extend the bearing’s service life, reduce the need for relubrication, and provide enhanced protection in harsh or demanding environments.

Sealed bearings are typically designated with the suffix “RS” or “2RS” in the bearing model or part number. The “RS” suffix indicates a single seal on one side of the bearing, while “2RS” indicates seals on both sides.

It’s important to note that while sealed bearings provide superior protection against contaminants, they may generate slightly more friction and heat due to the increased sealing contact compared to shielded bearings. This can result in a slightly lower operating speed or higher torque compared to shielded bearings.

The choice between a shielded bearing and a sealed bearing depends on the specific requirements of the application, including the level of contamination risk, the need for maintenance and relubrication, and the operating conditions. Consulting with bearing manufacturers, distributors, or industry experts can help in selecting the most appropriate bearing type for a given application.

Overall, shielded bearings and sealed bearings are both effective solutions for protecting rolling bearings, and the selection depends on the desired level of protection and the specific application requirements.
