Bearings are available in a variety of materials. Fabricators and manufacturers regularly employ chrome steel (particularly SAE 52100) stainless steel (usually the 300 series), low and medium carbon alloy steel, ceramics and even plastics. However, when looking at the material employed for bearings, it is no surprise that bearing bronze is a favorite. Bearing bronze is undeniably one of the most versatile metals to use in producing bushings. Bearing bronze bushings are commonly available and reliable for the functions they must fulfill.
Bearing bronze is available in different types or classifications. This includes both leaded and non-leaded varieties. A common type often employed for bushings, bearings, sprockets, washers and other similar components is C93200, a highly leaded tin bronze that is 80% copper, 10% tin, and 10% lead.
Bronze Bars C93200 (SAE 660)
This bar stock is a general utility product. With its very smooth and high-quality finish, it is an excellent choice for both bushings and bearings. This readily available bearing bronze possesses the following attractive qualities:
- Excellent machining
- Increases longevity making it an excellent choice where wear and tear is heavy
- High impact resistance
- Resistant to corrosion and wear and tear
- Good anti-friction properties
- Sufficient and cost-effective strength
- Adequate hardness
- Reasonable ductility
C93200 also known as 80-10-10 bronze due to its composition, is perfect for general-purpose applications including bronze bushings for pumps, cylinders, and earth moving equipment.
C93200 Bronze Bushings
C93200 is one of the most commonly requested bearing bronzes. It is often described as the workhorse of the bearing bronze alloys. With a wider applicability than the other highly leaded tin bronzes, it finds use in many applications requiring light and medium loads and speeds. As a popular general utility metal, alloy C93200 is a cost-effective means of manufacturing durable and good quality bronze bushings and bearings for a myriad of common applications in diverse industries.
