Lead-Free Bronze Bearings, Sleeve and Plain Bearing

We produce lead-free bronze alloys bearing and bushing upon request. In the world of machinery components, the transition to more environmentally conscious materials is crucial. Lead-free bronze bearings are at the forefront of this change, offering a safer and equally efficient alternative to traditional leaded bronze bearings. Made from innovative bronze alloys, these bearings eliminate lead, replacing it with elements like bismuth to retain the favorable mechanical properties without the health risks.

Common Lead-Free Bronze Alloy， Leaded Bronze Bushings and Bearings

We specialize in large-size centrifugal bushes, rings, and sleeves, crafted with precision by our team of skilled engineers, technicians, and bearing bronze alloy experts. Explore our products to see what we offer.

Leaded bronze, known for its high lead content, offers superior dry running properties and results in a softer material. This composition adjusts its mechanical properties when operating temperatures exceed 200°C. Leaded bronze is particularly suited for bearings under high surface pressure due to its acid resistance and compatibility with water lubrication. We offer leaded bronze bushings in alloys such as CuSn10Pb10 (CC495K) and CuSn7Pb15 (CC496K), catering to diverse application needs.

Leaded bronzes are renowned for their superior corrosion resistance and robust operational properties. Below, you can explore a selection of our most sought-after leaded bronze alloys. Additionally, we specialize in crafting custom alloys tailored to meet the specific requirements of our clients.

Bronze Alloy: CuSn10Pb10-C Specifications
