Product Overview

C93200 bearing bronze CNC parts are precision-engineered components manufactured from C93200 alloy, a high-lead tin bronze specifically designed for bearing and bushing applications. Also known as SAE 660 bronze, this alloy contains approximately 83% copper, 7% tin, and 7% lead, along with small amounts of zinc and nickel. The high lead content provides excellent self-lubricating properties, making C93200 bronze ideal for applications where continuous lubrication is difficult or impossible. This material conforms to ASTM B505 and ASTM B27 standards for continuous cast bronze bearing alloys.

Our advanced CNC machining capabilities enable us to produce custom C93200 bearing bronze parts with exceptional precision and tight tolerances. The material's excellent embeddability allows dirt and debris to be embedded into the bearing surface, preventing damage to shafts and rotating components. The conformability characteristics enable the bronze to adapt to minor misalignments and shaft deflections, ensuring smooth operation even under less-than-ideal conditions. Our experienced engineering team works closely with you from design to delivery, ensuring your parts meet exact specifications while maintaining the material's superior bearing properties.

We offer comprehensive surface finishing options for your C93200 bearing bronze parts, including standard oil impregnation for enhanced lubrication, precision machining for optimal surface finish, and custom sizing to match your shaft specifications. With no minimum order quantity and fast delivery, we're ready to meet your production needs, whether you require a single prototype or high-volume production of precision bronze bearings, bushings, thrust washers, or wear plates for industrial machinery, automotive applications, marine equipment, or heavy-duty mechanical systems.

Frequently Asked Questions

What makes C93200 bronze suitable for bearings?

C93200 bearing bronze contains 7% lead which provides excellent self-lubricating properties. The lead acts as a solid lubricant, allowing the bearing to operate effectively even without continuous external lubrication. Its embeddability allows debris to be embedded into the soft bronze matrix, preventing shaft damage.

What is the minimum order quantity for C93200 bronze CNC parts?

We have no minimum order quantity. Whether you need a single prototype or thousands of production parts, we can accommodate your requirements with the same level of precision and quality.

What is the typical lead time for C93200 bronze parts?

Prototype orders typically ship within 3-5 business days. Production orders usually take 7-14 days depending on quantity and complexity. Expedited options are available for urgent requirements.

What is the difference between C93200 and other bearing bronzes?

C93200 (SAE 660) is the most widely used general-purpose bearing bronze with balanced properties. It offers good load capacity, excellent self-lubrication, and conformability. Compared to C95400 aluminum bronze, C93200 has better self-lubricating properties but lower strength. Compared to C51000 phosphor bronze, C93200 has better embeddability but lower fatigue resistance.

Does C93200 bronze require external lubrication?

While C93200 bronze has excellent self-lubricating properties due to its lead content, external lubrication is still recommended for optimal performance and extended bearing life. The self-lubricating property provides protection during startup and in applications where lubrication may be intermittent.
