What are Bronze Graphite Bearing Bushings?

Bronze Graphite Bearing Bushings are uniquely designed for high-load, low-speed applications. Made of rotational cast high-strength bronze, they utilize a specially formed graphite plug as a lubricant. This combination enables these bushings to withstand temperatures of up to 400°C (800F) and as low as -200°C (-400°F), depending on the material chosen.

Specifications:

• Structure: CuZn25Al6Mn4 Bronze with solid graphite lubricant inserts (alternative specifications available on request)
• PV (N/mm² x m/s): 3.3 max
• Static load (N/mm²): 100 max
• Sliding speed (m/s): 0.3 max
• Operating temperature (°C): Up to 300 (alternative specs up to 400)
• Coefficient of thermal expansion: 19 x 10-5/°C
• Coefficient of friction: 0.16
• Hardness (HB): 210 min
• Tensile strength (N/mm²): 750 min
• Elongation (%): 12 min
• Density (g/cm³): 8

Notable Characteristics:

• Performance: They excel under high load, low speed operations, even without lubrication.
• Durability: These bushings have unmatched wear resistance in situations where forming an oil film is challenging.
• Resistance: They offer substantial resistance to corrosion and chemical attacks.
• Maintenance: With their self-lubricating properties, they save on operating costs and are maintenance-free.

Applications:

From cargo handling equipment to turbines and hoisting equipment, these bushings find their place in a wide range of applications due to their:

1. Insensitivity to dirty environments
2. Resilience against shock loads and vibrations at slow speeds
3. Capability to operate with a poor shaft surface finish
4. Resistance to corrosive conditions

Design Varieties:

Whether it’s cylindrical bearings, flanged bearings, thrust washers, or plates, we’ve got you covered. Special designs and materials can be crafted as per your requirements.

Bronze Guide Blocks for Automation Systems:

Traditional bronze bearings are often cylindrical. However, some bronze bearings, referred to as guide blocks, wear plates, and liners, break this mold. Milled to perfection, these bearings leverage the properties of bronze alloys to provide superior metal-to-metal friction solutions.

Recent advancements allowed us to manufacture these components for a leading automated systems manufacturer. By utilizing a cutting-edge CNC machine, we ensured the final product adhered to the strictest tolerances, free of defects.

One of the primary materials used, C93200 SAE 660 bearing bronze alloy, boasts exceptional bearing properties due to the inclusion of a small amount of lead. This lead not only enhances machinability but also offers internal lubrication during dry starts. However, it’s essential to note that while this alloy offers many benefits, it isn’t self-lubricating.

For applications requiring no external lubrication, we offer a solution: we will machine your part in C93200 SAE 660 and then introduce solid lubricant inserts. These graphite-based inserts provide the necessary self-lubrication for critical applications, especially where high temperatures might cause standard lubricants to burn off.

In Conclusion:

Bronze Guide Blocks Plugged Graphite is revolutionizing the parts forming industry. As a leading manufacturer of die component products, we pride ourselves on delivering unmatched service and quality you can trust. Whether it’s wear plates, gibs, guide blocks, or any other component, our commitment to excellence remains unwavering. With our solutions, industries worldwide can move towards a more efficient and reliable future.

Inch and Metric Die Components: Bridging Standards for Optimal Performance

In the constantly evolving world of manufacturing and industrial design, adaptability and precision are paramount. Recognizing this, our product line offers both inch and metric size die components designed to cater to various die standards, ensuring compatibility and excellence across diverse industrial applications.

Embracing International Standards

Our commitment to quality and versatility sees our components being designed to several renowned die standards:

• ISO (International Organization for Standardization)
• NAAMS (North American Automotive Metric Standards)
• JIS (Japanese Industrial Standards)
• Additionally, we cater to the unique requirements of many large automotive and appliance manufacturers.

Comprehensive Product Offering

We pride ourselves on offering a diverse range of products, tailored to meet the varying needs of our clientele:

1. Wear Products: This category includes both standard and self-lubricating products:
   • Wear plates
   • Wear strips
   • Gibs
   • Keeper plates
   • Guide blocks
2. Guide Posts & Bushings: Essential for ensuring accurate alignment and smooth operation.
3. Die Springs: We provide springs compliant with both ISO and JIS standards, ensuring flexibility and adaptability.

All our guide and keeper blocks are constructed of bronze, integrated with self-lubricating graphite plugs. This ensures longevity, reduced wear and tear, and optimal performance.

Sizing and Customization

Understanding that one size doesn’t fit all, we offer:

• Both metric (NAAMS) and inch sizes for guide and keeper block items.
• Custom size lengths available in both metric and inch dimensions, catering to requirements up to 12 inches or 300 mm.

Keeper blocks, in particular, play a vital role in ensuring the alignment of loads, facilitating a smooth die operation, and preventing undue wear and tear.

Features That Stand Out

Our products are not just about compatibility; they’re about setting industry standards:

• Self-Sufficiency: They can operate efficiently without oil for extended periods.
• High Load Capacity: Designed to bear immense loads, they boast superior anti-wear properties and minimal friction.
• Versatility: Perfect for operations involving reciprocating, oscillation, or intermittent motion where maintaining an oil film is challenging.
• Chemical Resistance: Our products display commendable resistance to chemicals and corrosion, increasing their lifespan and reliability.
• Temperature Range: Suitable for a vast temperature range, they can adapt to various industrial environments.
• Solid Lubricants: The incorporation of solid lubricants like graphite ensures smooth operation and reduces the need for frequent maintenance.
