C90500 BRONZE BEARING SOLUTIONS
Gunmetal, a bronze alloy composed mainly of copper, tin, and often zinc or lead, is valued for its strength and wear resistance, making it ideal for bearings. Its performance is further enhanced with graphite plugging.
C90500 Gunmetal Bronze is commonly used in bearings, bushings, pump sleeve bushings, gears, and high-strength bushings for low-speed, heavy-load conditions. Other applications include pump impellers, piston rings, steam fittings, valve bodies, movable bridge components, and fixed bearing structures subjected to slow or intermittent motion under heavy loads.
We specialize in bearings and related components, focusing on self-lubricating bearings as an alternative to plain or oil-free options. Our goal is to foster collaboration among engineers in academia and industry involved in bearing design, development, manufacturing, and maintenance. We produce custom-machined bronze components, including bushings and bearings, tailored to your specifications while ensuring on-time delivery and cost efficiency.

Self-lubricating bearings function without external lubricants by incorporating solid materials like lead, graphite, or molybdenum disulfide. The lubricant choice depends on performance, cost, maintenance, and operating conditions. For specific guidance, please provide application details.
Gunmetal Bronze Bearings: The Ultimate Choice In Durability And Precision
Plain bearing materials include bronze bushings and other alloys. Our gunmetal bearings are made from RG7 alloy, a machined bronze continuous cast material. For sizes with an inner diameter over 14 mm, these bearings feature an inner grease groove that helps establish a lubricating film on the sliding surface, significantly reducing friction during operation. They are well-suited for medium to heavy loads and perform exceptionally in dirty environments, ensuring high performance and durability under challenging conditions.
Bronze RG5, also known as Leaded Gunmetal or C83600, is a type of bronze alloy that commonly consists of:
- Approximately 85% Copper (Cu)
- Approximately 5% Tin (Sn)
- Approximately 5% Lead (Pb)
- Approximately 5% Zinc (Zn)
These percentages can slightly vary based on the manufacturer’s specifications. RG5 bronze is celebrated for its excellent machinability, resistance to wear and corrosion, and its ability to achieve a fine surface finish. It is typically used in the production of bearings, bushings, and other components requiring a durable, wear-resistant material.
The alloys C83600 and C86300 represent two distinct types of bronze, each with different elemental compositions and properties. Here’s an overview:
C83600 (Leaded Red Brass or RG5)
- Comprises about 85% Copper, 5% Tin, 5% Lead, and 5% Zinc.
- Known for good machinability and corrosion resistance.
- Commonly used in bearings, valves, and fittings.
C86300 (Manganese Bronze or High Strength Yellow Brass)
- Contains approximately 60-68% Copper, 3-7% Tin, up to 7% Zinc, and 2.5-5% Aluminum, with 2.5-5% Manganese.
- Renowned for its high strength, superior load-bearing capacity, and excellent wear resistance.
- Often employed in heavy-duty applications such as gears, bridge components, and other high-strength parts.
The primary difference between C83600 and C86300 lies in their composition and the resulting mechanical properties, making them suitable for varying applications. C83600 offers easier machinability and good corrosion resistance, while C86300 is favored for its robust strength and load-bearing capabilities.
Comparison of RG5 and RG7 Bronze Alloys
- RG5 (Leaded Gunmetal or C83600): Composed of about 85% copper, 5% tin, 5% lead, and 5% zinc. It’s well-suited for general use in manufacturing components like bearings and valves due to its excellent machinability and corrosion resistance.
- RG7 (Tin Bronze or C93200): Typically contains about 87% copper, 7% tin, 3% lead, and 3% zinc. The increased tin content enhances strength and hardness, making it ideal for more demanding applications like gears and heavy-duty bearings.
RG5 is generally easier to machine and is apt for standard applications, whereas RG7, with higher tin content, offers better wear resistance and is suited for more strenuous conditions.
