What is Bushing Brass Sleeve
Bushing Brass SleeveBushing brass sleeve stands out as a top-tier product characterized by unmatched quality, versatile functionality, and an extended lifespan. Elevate your engineering applications with a component that combines precision craftsmanship with durable materials, ensuring optimal performance in every use case.Bearings and bushings are necessary for optimal functioning of any wheel application. Without it, the bore of the wheel is subject to constant friction-wearing it out faster and shortening its life span. This is especially important in industrial wheels that carry heavy loads, such as metal wheels at lumber mills or manufacturing plants.
Three Types of Bushing Brass Sleeve Designs Are Typically Used In Automotive Applications
Split (Butt Joint) bushing
Split bushings are generally used for low load or low speed conditions. The most common transmission use for this application is shift linkages, although some suppliers are now making them available to service internal transmission components.
Solid (No Seam) bushing
This type of bushing has the tightest wall and OD tolerances in use today. These bushings are manufactured with a layer of babbitt material and with seamless construction, making them easy to install. Additionally, their ridged structure eliminates the machine in place process, which may have been required at the OEM level.
Clinched (Puzzle Piece Design) bushing
This is a sintered-material, layered bushing and currently the most common type in use today. Several OEMs use this type of bushing. After installation, the OEM may bore the bushing to make sure they work efficiently. This process is called "machine in place" and is used on some transmissions to create a true bore after bore machining and bushing installation.
Process Of Bushing Brass Sleeve




Powder laying: Firstly, decontaminate and deoxidize the steel plate surface, and then prepare the required copper powder;
Sintering: The copper powder material can be transformed into dense body in the sintering process. After the powder is formed, the dense body obtained by sintering is a polycrystalline material, which affects the performance of the material. According to different technical requirements and steel plate thickness, alloy copper powder with a certain thickness is evenly paved on the surface of the steel plate, then heated with high temperature oxygen isolation, and sintered at 700-900 ℃ for 30-90 minutes. The metal other than copper is partially melted, and the alloy powder becomes paste. After cooling, it is firmly sintered on the steel plate;
Blanking: Cut the steel plate and copper plate into the specified length and width according to the product requirements;
Oil pressure groove: Punch out the oil groove with designed size on the bimetallic plate;
Punching buckle: Set punching buckle at the edge;
Pre bending: Place the alloy plate on the pre bending die for pre bending;
Bending: Combine the two ends of the alloy parts bent at both ends with the bending die;
Rounding: Shape the alloy parts with guide posts;
Extrusion: While shaping, the side matching the shape radius of the alloy part and the pressing die are used for final shaping;
Integration: Level the two end faces of the alloy parts on the grinder, chamfer the mouth at both ends, and finally finish grinding the outside of the alloy parts.
