Wrapped Acetal Lined

wrapped acetal lined bearings are suitable for rotary and oscillating movement applications.

The POM plain bearings are available in metric and imeprial sizes as standard. Our in-house machining service is able to offer non-standard sizes to suit customer specific requirements.

Our standard-wrapped bearing bimetals feature a steel-backed design with a sintered bronze lining. Known for their exceptional durability and versatility, these bearings are available in both metric and imperial sizes. Ideal for a variety of general-purpose and heavy-duty applications, they can be lubricated with either oil or grease. Additionally, our in-house machining service offers the flexibility to produce custom, non-standard sizes tailored to meet specific customer needs.

Specifically engineered for slow-speed, high-load scenarios, these bearings are particularly well-suited for oscillating motion.

They are an ideal choice for industries such as construction, mining/quarrying, agriculture, and automotive, where durability and performance under demanding conditions are essential.

Our range of oilless bearings offers an ideal solution for applications where lubrication is difficult to provide or where traditional lubricants may carbonize. Designing and maintaining oil-feeding systems can be both time-consuming and costly. By utilizing our oilless bearings, you can significantly reduce maintenance expenses and eliminate the need for such systems altogether.

These bearings are specifically engineered for high-load, low-speed applications and are manufactured from rotationally cast high-strength bronze, incorporating specially designed graphite plugs as a built-in lubricant. Our oilless bearings are graphite-loaded, enabling them to operate in extreme conditions, withstanding temperatures up to 400°C (800°F) and cryogenic temperatures as low as -200°C (-400°F), depending on the material selected.

Typical applications include, but are not limited to:

• Kilns

• Dryers

• Injection molding machines

• Dust collectors

• Louvers

• Hot conveyors

Oilless bearings boast exceptional chemical and corrosion resistance. The lubricant used in these bearings, made from abrasion-resistant materials such as graphite or PTFE, features a stabilized molecular structure, ensuring long-lasting performance. These bearings are suitable for a variety of environments, including dry conditions where contamination is a concern, high-humidity or wet applications, and hard-to-reach locations. Oilless bearings are truly lubricated for life! For tailored solutions, our technical team is available to help you determine the most suitable combination for your specific application.

When selecting the right bushing size for your application, it’s essential to consider several factors to ensure optimal performance and longevity. Here’s a comprehensive guide to help you through the process:

1. Understand the Application Requirements

• Load Capacity: Determine the radial and axial loads the bushing will need to support. This includes both static and dynamic loads.

• Speed: Consider the rotational or oscillating speed of the application. High-speed applications may require bushings with low friction coefficients.

• Environment: Assess the operating environment, including temperature, humidity, exposure to chemicals, and potential contaminants. This will influence the material selection.

• Lubrication: Determine whether the bushing will be self-lubricating, require external lubrication, or operate dry.

2. Material Selection

• Bronze: Commonly used for its excellent wear resistance and load-bearing capacity. Ideal for high-load, low-speed applications.

• Plastic/Polymer: Suitable for applications requiring corrosion resistance, low friction, and quiet operation. Often used in food processing or medical equipment.

• Steel: Used in high-strength applications, often with a coating or plating for corrosion resistance.

• Composite Materials: Combine the benefits of different materials, such as metal and polymer, for enhanced performance in specific conditions.

3. Size and Dimensions

• Inner Diameter (ID): Must match the shaft diameter. Ensure a proper fit to avoid excessive wear or play.

• Outer Diameter (OD): Should fit snugly into the housing or bore. Consider the tolerance for press-fit or slip-fit installations.

• Length: The length of the bushing should be sufficient to distribute the load evenly without causing excessive wear.

• Flange Dimensions (if applicable): For flange bushings, ensure the flange diameter and thickness are appropriate for the application.

4. Tolerance and Fit

• Clearance Fit: Allows for easy assembly and disassembly, suitable for applications with low precision requirements.

• Interference Fit: Provides a tight fit, ideal for high-precision applications where minimal movement is required.

• Transition Fit: A balance between clearance and interference fits, used in applications requiring moderate precision.

5. Special Considerations

• Custom Sizes: If standard sizes do not meet your requirements, consider custom-made bushings. Ensure you provide detailed specifications, including dimensions, material, and any special features.

• Metric vs. Imperial: Depending on your region or industry standards, choose between metric and imperial sizes. Ensure compatibility with other components in your system.

6. Consultation and Quotation

• Expert Advice: If unsure, consult with a bearing specialist who can provide recommendations based on your specific application.

• Quotation: Request a quote for the required bushings, including any custom sizes or materials. Ensure the supplier can meet your delivery timelines and quality standards.

7. Testing and Validation

• Prototype Testing: For critical applications, consider testing a prototype bushing to validate its performance under real-world conditions.

• Quality Assurance: Ensure the supplier adheres to industry standards and provides certifications if required.

8. Installation and Maintenance

• Proper Installation: Follow manufacturer guidelines for installation to avoid damage and ensure optimal performance.

• Maintenance: Regularly inspect and maintain the bushings to extend their lifespan. This may include lubrication, cleaning, or replacement as needed.

By following this guide, you can select the appropriate bushing size and type for your application, ensuring reliable performance and longevity. Whether you need standard sizes or custom solutions, working with a knowledgeable supplier will help you achieve the best results.
