We specialize in manufacturing and supplying self-lubricating composite bushings that offer excellent wear resistance and low friction properties. As a global supplier of DU bushings, we are committed to advancing our position in the market. We offer a wide range of sliding bushing types in standard dimensions, including cylindrical bushes, flanged bushes, thrust washers, flanged washers, and sliding plates. Additionally, we can manufacture metric and imperial self-lubricating bushings to order from our facilities in China. Whether you need standard sleeve bushing types or customized parts with specific dimensions, thrust washer variations, or special inch sizes, we can accommodate your requirements based on stamping drawings or deep drawing techniques. Our aim is to provide top-quality self-lubricating bushing designs that meet your expectations.

As a bushing exporter, we are flexible when it comes to minimum order values and quantities, ensuring that even small orders can be fulfilled promptly. We prioritize fast delivery to ensure your needs are met in a timely manner.

Our self-lubricating bushings are available in cylindrical and flanged sleeve designs, with various dimensions to suit your specific needs. The dimensions are typically specified as Inside Diameter x Outside Diameter x Length for cylindrical bushes, and Collar Bushings Flange Size for flanged bushes. We offer a range of self-lubricating bushings with bronze plating in a flanged type, and they are lined with PTFE (polytetrafluoroethylene). These bushings provide excellent lubrication properties and are suitable for various applications.

For your convenience, we provide a standard cylindrical self-lubricating bushing size chart, available in both metric and inches. If you require specific sizes, please let us know, and we will be happy to assist you in finding the correct replacement size from our Garlock bushings range to meet your requirements. Our self-lubricating bushings are designed to deliver high performance in a variety of operating conditions. They perform very well in dry conditions and exhibit good performance when oil lubrication is used. When grease lubrication is applied, the performance is fair. These bushings also provide fair performance when lubricated with water or process fluids.

The self-lubricating bushing material we use consists of a steel back, a porous bronze sinter layer, PTFE (polytetrafluoroethylene), and lead. This combination ensures optimal lubrication and reduces friction during sliding operations. The self-lubricating bushing you are referring to is composed of several layers. The first layer is a steel backing, which provides strength and support to the bushing. On top of the steel back, there is a layer of porous bronze sinter. This layer helps with the distribution of lubricant and provides additional structural integrity. The next layer is a PTFE (polytetrafluoroethylene) sliding layer. PTFE is known for its low friction properties, which allow for smooth and efficient sliding between surfaces. This layer acts as a solid lubricant, reducing friction and wear. Finally, there is a layer of lead, which further enhances the self-lubricating properties of the bushing. Lead assists in the formation of a thin lubricating film during operation, ensuring a continuous and reliable lubrication process. This combination of materials—steel back, porous bronze sinter, PTFE sliding layer, and lead—results in a high-quality self-lubricating bushing that offers excellent wear resistance and low friction performance.
