C83600 Bearing Bronze
C83600 — also known as SAE 40, CDA 836, or 85-5-5-5 red brass — is a leaded tin-zinc casting bronze containing roughly 85% copper, 5% tin, 5% lead, and 5% zinc. It is the most widely used casting alloy for general-purpose bushings and bearings because it combines good corrosion resistance, reliable load capacity, and the easiest machinability of any standard bearing bronze.
If you are specifying a cast bronze bushing for moderate loads and speeds — a pump sleeve, a valve stem nut, a gear blank, or a custom-machined bearing — C83600 is usually the first alloy on the shortlist.

C83600 vs C86300 vs C95400 — Which One Fits?
These three alloys are frequently quoted against each other. The differences are significant:
| Alloy | Family | Tensile (typ.) | Best for |
|---|---|---|---|
| C83600 (SAE 40) | Leaded red brass | ~235 MPa | General bushings, corrosion resistance, machinability |
| C86300 (SAE 430B) | Manganese bronze | ~820 MPa | Very high loads, slow speeds |
| C95400 | Aluminum bronze | ~585 MPa | High strength + corrosion, marine and heavy equipment |
Rule of thumb: choose C83600 when machinability and corrosion resistance drive the decision; C86300 manganese bronze when the load is the dominant constraint; C95400 aluminum bronze when you need both strength and seawater corrosion resistance.

SAE 40 Self-Lubricating Bronze Bearings
SAE 40 self-lubricating bronze bearings, crafted from durable copper alloy, are pivotal in enhancing electrostatic precipitation systems. Widely employed in industrial settings, these bearings excel in environments demanding wear and impact resistance. In Electrostatic Precipitators (ESPs), they serve crucial roles in the transmission shaft, shaking mechanism, and guiding system.
In ESPs, SAE 40 self-lubricating bronze bearings find application in critical components such as the shaking mechanism, transmission system, and guiding system. These components endure heavy dust pollution and require stable operation. The self-lubricating nature of SAE 40 bearings effectively reduces friction and wear caused by dust accumulation, thus prolonging equipment lifespan and maintenance cycles.
SAE 40 bearings are ideal for ESPs due to their exceptional wear and corrosion resistance. They ensure stable equipment operation in harsh environments, while their low friction coefficient and good mechanical properties enhance system efficiency and reliability. Additionally, their corrosion resistance makes them well-suited for the high humidity and corrosive environments encountered in ESPs, ensuring long-term operational efficiency.
