Oil-free cast bronze bushings, integrated with solid lubricant inserts, offer a unique and efficient solution for lubrication-free operations. These bushings are designed to eliminate the need for regular oiling, significantly reducing maintenance requirements and operational costs.
The cast bronze material used in the bushings is renowned for its exceptional strength, durability, and wear resistance. This ensures that the bushings can withstand heavy loads and maintain their performance even under extreme conditions.
The solid lubricant inserts are a key feature of these bushings. These inserts are made from a high-performance material that releases lubricating particles as the bushing rotates, providing a continuous and reliable lubricating layer between the bushing and the mating surface. This eliminates the need for external lubrication, ensuring smooth and friction-free operation.
The combination of cast bronze and solid lubricant inserts creates a bushing that is not only durable but also self-lubricating. This makes it an ideal choice for a wide range of industrial applications, particularly those that require reliable and maintenance-free bearing solutions.
In addition to their lubrication-free operation, these bushings are also easy to install and maintain. Their robust design and material choice ensure long-term reliability and performance, minimizing downtime and operational disruptions.
Overall, oil-free cast bronze bushings with solid lubricant inserts provide a cost-effective and efficient solution for lubrication-free bearing applications, offering superior performance, durability, and maintenance-free operation.
1. It can work under oil-free lubrication or oil less condition for a long time, with good self-lubrication performance. 2. More suitable for heavy load and low speed working conditions, with very good wear resistance and very low friction coefficient. 3. Suitable for reciprocating, rotating, oscillating and intermittent motion, etc. where oil film is difficult to form. 4. With corrosion and chemical resistance.
High force brass part can also be drilled and graphited.
45# steel ring High force brass as the base and inlaid with solid lubricant. Using the frictional heat in use to form a self-lubricating film of oil and ultra-fine powder mixture, breaking through the limitations of general bearings rely on oil film lubrication. High hardness, excellent wear resistance and high load bearing capacity.
