PB2 Phosphor Bronze BushingAs a manufacturer of Bronze bearings and bushings, we employ the casting route, specifically using sand casting and centrifugal casting techniques. Sand casting is a traditional method that involves creating molds from compacted sand, while centrifugal casting uses centrifugal force to distribute molten metal into a mold, producing high-quality cylindrical components like bushings.

Our process ensures that the PB2 Bronze components are supplied in proof machine condition and can also be provided with a final grinding finish as per the customer’s specific requirements. This flexibility allows us to cater to various industries and applications with precise tolerances and surface finishes.

Quality Control

At our facility, maintaining the desired material composition is of utmost importance. We have our own material testing laboratory where we conduct rigorous chemical and mechanical testing. This enables us to adhere to customer-specific requirements and ensure that the PB2 Bronze alloy meets the necessary standards for performance and durability.
