Oil Free Bushings(Case Shape:Oval Shaped Flange)

Since bearings usually receive a lot of frictional resistance that generates heat, lubricants such as oil or grease are used to prevent the seizing or abnormal wear that this frictional heat could otherwise cause. Lubrication-free bushings don't need lubricating oil because the bearing body has a lubricating structure

Since bearings usually receive a lot of frictional resistance that generates heat, lubricants such as oil or grease are used to prevent the seizing or abnormal wear that this frictional heat could otherwise cause. Lubrication-free bushings don't need lubricating oil because the bearing body has a lubricating structure made possible by lubricating oil in the bearing body, or by embedded solid lubricant or the like. Since they don't need lubricating oil, lubrication-free bushings are often used for applications such as precision machinery that makes lubricating oil refilling difficult, and equipment with poor affinity to oil. They also greatly reduce maintenance costs by eliminating the need for regular lubrication and enabling stable operation over long periods. Lubrication-free bushings come in a variety of shapes that can be used for different applications as needed. Examples include straight bushings, collar bushings, flange bushings and housing bushings.

            FAQ Oil Free Bushings

            Question: What does the term ″self-lubricating bushing″ refer to?
            Answer: The term ″self-lubricating bushing″ refers to a type of bearing or sleeve that has the ability to provide lubrication to reduce friction without requiring external lubricants like oil or grease. These bushings are designed with embedded solid lubricants, such as graphite or PTFE (Teflon), which release lubrication during operation. They are commonly used in various applications where low friction, smooth operation, and maintenance-free performance are desired, such as in machinery, automotive components, and industrial equipment.
            Question: Should you apply grease or oil to bronze bushings?
            Answer: In general, bronze bushings do not need additional grease or oil. They are self-lubricating and don't require external lubrication. However, if there is excessive friction or wear, a small amount of compatible oil or grease can be applied. It's best to follow the manufacturer's recommendations or seek professional advice for specific bronze bushings.
            Question: What materials are typically used to manufacture self-lubricating bushings?
            Answer: Self-lubricating bushings are usually made from materials like bronze, brass, steel, PTFE (Teflon), nylon, and composites. These materials have built-in lubrication properties, reducing the need for external lubricants. Bronze and brass are durable choices, steel is strong, PTFE offers low friction, nylon is lightweight, and composites provide a balance of strength and self-lubrication. Material selection depends on specific application requirements.
            Question: Are bronze bushing self-lubricating?
            Answer: Yes, bronze bushings are self-lubricating. They contain built-in solid lubricants like graphite or PTFE. This means they can provide lubrication on their own, reducing friction and wear. They don't require additional external lubrication, making them convenient and suitable for various applications.
