Product Description

The thin-walled bearing realizes the extremely thin bearing section, and also realizes the miniaturization and light weight of the product. The variety of products expands its scope of use. In order to obtain the bearing’s low friction torque, high rigidity, and good rotation accuracy, steel balls with a small outer diameter are used. The use of hollow shafts ensures light weight and space for wiring.The series has a variety of dust cover forms, stainless steel forms, and wide forms, etc.
The uniform section thin-walled bearing is composed of 7 open series and 5 sealed series. There are 3 types of open series: radial contact C type, angular contact A type and four-point contact X type. The advantages of thin-walled constant-section bearings: thin-walled bearings achieve extremely thin bearing cross-sections, and achieve product miniaturization and light weight. The variety of products has expanded its scope of use. Stepper motors, medical equipment, office equipment, test equipment, speed reducers, robots, optical imaging equipment, rotary encoders.
   Thin-walled constant-section bearings are also called thin-walled ring bearings, which have high precision, very quiet characteristics and strong load-carrying capacity. The thin-walled bearings with constant cross section can be deep groove ball bearings, four-point contact ball bearings, angular contact ball bearings and thin-walled bearings with the same cross section, and the cross section is mostly square. In these series, even with larger shaft diameters and bearing holes, the cross-section remains the same. Therefore, these bearings are called thin-walled constant-section bearings. It is this characteristic that distinguishes the thin-walled constant-section bearings in the standard ISO series from traditional bearings.
   Therefore, it is possible to select a larger cross section and use a bearing with a higher load carrying capacity without changing the shaft diameter. Thin-walled bearings with constant cross-section can be designed to be very light and require only a small space.

Can you provide guidance on the selection and sizing of plastic bearings for specific applications?

Yes, I can provide guidance on the selection and sizing of plastic bearings for specific applications. Here’s a detailed explanation:

  • 1. Identify Application Requirements:

The first step in selecting plastic bearings for a specific application is to identify the application requirements. Consider factors such as load type, load magnitude, rotational speed, temperature range, environmental conditions, chemical exposure, and any specific performance criteria. Understanding these requirements will help in choosing the right type of plastic bearing that can meet the demands of the application.

  • 2. Evaluate Load Capacity:

Next, evaluate the load capacity required for the application. Plastic bearings have different load ratings depending on the material and design. Consider the expected static and dynamic loads that the bearing will need to support. It is important to select a plastic bearing with a load capacity that exceeds the anticipated loads to ensure reliable and long-lasting performance.

  • 3. Consider Speed Limitations:

Take into account the rotational speed or linear velocity of the application. Plastic bearings may have speed limitations due to factors such as heat generation, friction, or material properties. Ensure that the selected plastic bearing can operate within the desired speed range without experiencing excessive wear, heat buildup, or failure.

  • 4. Assess Environmental Factors:

Consider the environmental factors that the plastic bearing will be exposed to. Evaluate the presence of moisture, dirt, chemicals, or other contaminants in the application. This will help determine the required level of corrosion resistance, chemical compatibility, or sealing features needed in the plastic bearing to ensure optimal performance and longevity in the specific environment.

  • 5. Choose the Right Material:

Selecting the appropriate plastic material is crucial for the performance of the bearing. Different plastic materials have varying properties such as temperature resistance, chemical resistance, wear resistance, and load capacity. Consider the specific requirements of the application and choose a plastic material that aligns with those requirements. Some common plastic materials used for bearings include PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), PA (polyamide), and UHMWPE (ultra-high-molecular-weight polyethylene).

  • 6. Consulting with Manufacturers:

When in doubt, it is advisable to consult with bearing manufacturers or industry experts. They can provide valuable guidance based on their expertise and experience. Manufacturers can help in selecting the appropriate plastic bearing type, size, and material for the specific application. They can also provide technical datasheets, catalog information, and recommendations to ensure the best possible selection and sizing of plastic bearings.

In summary, selecting and sizing plastic bearings for specific applications involves identifying the application requirements, evaluating load capacity and speed limitations, assessing environmental factors, choosing the right material, and consulting with manufacturers or industry experts. By following these guidelines and considering the specific needs of the application, you can make an informed decision and select plastic bearings that will deliver optimal performance and reliability in your specific industrial or mechanical application.

How do plastic bearings perform in wet or corrosive environments?

Plastic bearings are known for their excellent performance in wet or corrosive environments. Here’s a detailed explanation of how plastic bearings perform in such conditions:

  • 1. Corrosion Resistance:

Plastic bearings exhibit high corrosion resistance, making them well-suited for wet or corrosive environments. Unlike metal bearings that can rust or corrode when exposed to moisture or corrosive substances, plastic bearings are unaffected by these conditions. They can resist the effects of water, chemicals, acids, alkalis, and other corrosive agents, ensuring long-term functionality and preventing premature failure.

  • 2. Moisture Resistance:

Plastic bearings have inherent moisture resistance properties. They are not affected by water absorption, which can cause dimensional changes and degradation in some materials. Plastic bearings maintain their shape, dimensional stability, and mechanical properties even when exposed to high levels of moisture or humidity. This makes them suitable for applications where water or moisture is present, such as marine environments, wastewater treatment plants, or outdoor equipment.

  • 3. Chemical Resistance:

Plastic bearings offer excellent resistance to a wide range of chemicals, including acids, bases, solvents, and oils. They are inherently non-reactive, which means they do not undergo chemical reactions or degradation when exposed to various chemical substances. This chemical resistance allows plastic bearings to perform reliably in environments where exposure to corrosive chemicals is common, such as chemical processing plants or laboratories.

  • 4. Self-Lubrication:

Many plastic bearings are self-lubricating, meaning they have built-in lubrication properties that eliminate the need for external lubrication. Self-lubricating plastic bearings are often impregnated with solid lubricants, such as PTFE (polytetrafluoroethylene) or graphite, which provide a low-friction interface between the bearing surfaces. This self-lubrication feature allows plastic bearings to maintain their performance even in wet or corrosive environments, where traditional lubricants may wash away or be compromised.

  • 5. Reduced Contamination:

Plastic bearings contribute to reduced contamination in wet or corrosive environments. Unlike metal bearings that can generate wear particles or rust, plastic bearings do not shed particles or corrode, minimizing the risk of contamination. This is particularly important in applications where cleanliness is crucial, such as food processing, pharmaceutical manufacturing, or cleanroom environments.

  • 6. Lightweight:

Plastic bearings are lightweight compared to metal bearings. This makes them advantageous in wet or corrosive environments, as they can reduce the overall weight of the equipment or machinery. Additionally, the lightweight nature of plastic bearings reduces the load on supporting structures and allows for more efficient operation in these environments.

In summary, plastic bearings perform exceptionally well in wet or corrosive environments. Their corrosion resistance, moisture resistance, chemical resistance, self-lubrication properties, reduced contamination risk, and lightweight nature make them reliable and durable choices for applications where exposure to water, chemicals, or corrosive substances is prevalent.

What are the common types of plastic materials used for plastic bearings, such as PTFE or nylon?

Plastic bearings can be made from various types of plastic materials, each offering unique properties and advantages. Here are some common types of plastic materials used for plastic bearings:

  • 1. PTFE (Polytetrafluoroethylene):

PTFE is a widely used plastic material for bearings due to its excellent low friction and self-lubricating properties. PTFE bearings have a low coefficient of friction, which reduces wear and energy consumption. They can operate without additional lubrication, making them suitable for applications where lubrication is challenging or undesirable. PTFE bearings also have high chemical resistance and can withstand a wide temperature range.

  • 2. Nylon (Polyamide):

Nylon is another common plastic material used for bearings. It offers good wear resistance, low friction, and high strength. Nylon bearings can handle moderate loads and have self-lubricating properties. They are also resistant to chemicals and have excellent dimensional stability. Nylon bearings are often used in applications such as conveyor systems, automotive components, and machinery.

  • 3. POM (Polyoxymethylene):

POM, also known as acetal or Delrin, is a versatile engineering plastic used in bearings. POM bearings have low friction, high wear resistance, and good dimensional stability. They exhibit excellent strength and stiffness, making them suitable for applications with moderate loads. POM bearings are often used in industries such as automotive, electronics, and consumer goods.

  • 4. UHMWPE (Ultra-High Molecular Weight Polyethylene):

UHMWPE is a plastic material known for its exceptional wear resistance and impact strength. UHMWPE bearings can withstand heavy loads, have a low coefficient of friction, and offer good chemical resistance. They are often used in applications where high abrasion resistance and durability are required, such as in material handling equipment, conveyor systems, and agricultural machinery.

  • 5. PEEK (Polyetheretherketone):

PEEK is a high-performance plastic material with excellent mechanical properties and temperature resistance. PEEK bearings can operate at high temperatures, making them suitable for applications in demanding environments. They offer low friction, good chemical resistance, and high strength. PEEK bearings are commonly used in aerospace, automotive, and medical applications.

These are just a few examples of the plastic materials used for plastic bearings. Other plastic materials, such as polyimide, PPS (polyphenylene sulfide), or PVDF (polyvinylidene fluoride), can also be used depending on the specific application requirements. The choice of plastic material for a plastic bearing depends on factors such as load capacity, temperature range, chemical compatibility, and friction characteristics.
