Bearing Bronze Stock – Maintenance Free Sliding Elements

When you’re searching for bearing bronze stock, you’re not just looking for a block of metal. You’re looking for a reliable, high-performance material that will serve as the foundation for critical components in machinery. At Bronze Oilless, we understand this completely. That’s why we’ve specialized in manufacturing bronze products, providing solutions that go beyond simple stock.

Whether you need standard parts or a custom solution, we’ve got the expertise and products to meet your needs. Let’s take a closer look at our offerings and how they can benefit your specific applications.

Our Specialized Bearing Bronze Products & Their Applications

We take standard bearing bronze stock and transform it into highly engineered products ready for use. Here’s a breakdown of what we offer and where our parts shine:

Cast Bronze Bushings

These are the workhorses of many industrial applications. Cast bronze bushings provide excellent wear resistance and load-bearing capabilities. They are commonly found in:

• Heavy machinery: Think construction equipment, cranes, and agricultural machinery.
• Pumps and valves: Ensuring smooth operation in fluid handling systems.
• Automotive suspensions: Providing a durable bearing surface.

Our cast bronze bushings can be customized with grease grooves to ensure proper lubrication, extending the lifespan of your equipment.

Flanged Bronze Bushings

A flanged bronze bushing is a great choice when you need to handle both radial and thrust loads. The flange provides a secure mounting point and prevents axial movement, making them ideal for:

• Industrial gearboxes and transmissions: Where shafts need to be precisely aligned.
• Conveyor systems: Supporting rollers and shafts under load.
• Electric motors: Providing a stable bearing for the rotor.

Bronze Thrust Washers

When dealing with axial loads (forces parallel to the shaft), a bronze thrust washer is essential. They are designed to prevent wear and friction between moving parts, making them crucial for:

• Pumps and compressors: Managing the thrust created by impellers.
• Automotive differential assemblies: Handling the significant axial forces during operation.
• Machine tool spindles: Ensuring precise movement and durability.

Oilless Plates & Custom Bushings

Our oilless plates and bushings are a game-changer for applications where traditional lubrication isn’t feasible or desired. By adding solid graphite plugs, these self-lubricating parts eliminate the need for regular maintenance. They are perfect for:

• Food and beverage processing: Where cleanliness is a top priority.
• High-temperature environments: Such as ovens or kilns where grease would break down.
• Underwater applications: Where grease would wash away.
• Machinery in remote or hard-to-reach locations: Reducing maintenance costs and downtime.

Bearing Bronze Stock and Custom Finished Components

Introduction

Bearing bronze has long been a trusted material in heavy-duty machinery applications thanks to its outstanding combination of strength, wear resistance, and self-lubricating properties. When paired with advanced design options such as graphite inserts and screw holes tailored to specific requirements, bearing bronze components offer unmatched performance and longevity.

At Bronzeoilless.com, we supply both standard bearing bronze stock and custom-finished components, ensuring that our customers receive parts tailored exactly to their application needs.

Base Material – High-Performance Bearing Bronze Alloy

Common Bearing Bronze Materials

Bearing bronze is a family of copper-based alloys specifically engineered for durability, wear resistance, and excellent load-bearing properties. Below are some of the most widely used bearing bronze materials:

1. C93200 (SAE 660 Bearing Bronze)

• Composition: Copper, Tin, Lead, Zinc

• Features:

  • Excellent machinability

  • Good wear resistance

  • High conformability and embeddability (absorbs small dirt particles without damaging the shaft)

• Applications: Bushings, washers, and general-purpose bearings

2. C95400 Aluminum Bronze

• Composition: Copper with Aluminum and Iron

• Features:

  • Very strong and tough

  • High load capacity

  • Excellent corrosion resistance

• Applications: Heavy-duty bushings, marine hardware, and pump components

3. C95500 Nickel Aluminum Bronze

• Composition: Copper, Aluminum, Nickel, Iron

• Features:

  • Superior strength and hardness

  • Good resistance to shock and fatigue

  • Performs well in seawater and corrosive environments

• Applications: Gears, heavy roller bearings, and marine equipment

4. C86300 Manganese Bronze

• Composition: Copper, Zinc, Aluminum, Manganese, Iron

• Features:

  • Extremely strong

  • Handles very high loads and shock stresses

  • Less suitable for low-speed wear unless lubricated

• Applications: Crusher bushings, large machinery parts, heavy-duty bearings

5. C90500 Tin Bronze (Gun Metal)

• Composition: Copper and Tin

• Features:

  • High strength

  • Good resistance to wear and corrosion

• Applications: High-load bearings, valves, and pumps

✅ Summary:

• C93200 → General-purpose, easy machining

• C95400 & C95500 → Heavy-duty, strong, corrosion-resistant

• C86300 → High shock load capacity

• C90500 → High-strength classic bearing bronze

Customization Options for Finished Components

1. Graphite Inserts

To improve self-lubrication and minimize maintenance, graphite inserts can be embedded into the bearing bronze. These solid lubricants provide continuous lubrication, even in dry-running or high-temperature conditions. Benefits include:

Reduced friction and wear

Extended service life

Lower operating costs

Reliable performance under heavy loads

2. Machined Holes for Mounting

Custom bronze components can also be finished with holes for M8 screws (or other specifications as per the drawing). This ensures easy installation and secure fitting in your equipment. Each hole is precision-machined to meet exact dimensional requirements, guaranteeing accuracy and consistency.

Applications of Bearing Bronze Components

Our bronze stock and custom-made parts are widely used in industries such as:

• Steel Mills & Rolling Equipment
• Marine & Offshore Machinery
• Injection Molding Machines
• Heavy Presses & Mining Equipment
• Hydropower & Energy Generation Systems

Wherever high load, wear resistance, and long service life are demanded, our bronze alloys deliver.
