DAIDO METAL
Compound bearing (bushing type ) with low friction characteristics and that optimizes metal properties such as strength and dimensional stability.
This environmentally friendly, lead- free, self-lubricating bearing requires no additional lubricant and does not use any lead at all.
Daidyne DDK05 is a compound bearing that combines a low-friction polytetrafluoroethylene (PTFE) bearing surface with the strength and dimensional stability of a metal backing.
[Features]
· The bearing surface has such a low coefficient of static and dynamic friction so that the surface runs smoothly without lubrication.
· "Stick Slip" doesn't happen.
· Also safe to use in oil.
· Can be used within a temperature range of -200°C to +280°C.
· Adaptable to operations under high-load, impact load, intermittent operation and reciprocating motion.
· Free from electrostatic induction (when installed, each bearing has an electrical resistance of 1 to 10 Ω per 1cm2).
· Bearing surface has superior chemical resistance and is not affected by solvents such as petroleum and alcohol.
· Will not damage the surface of the engaging component.
· Extended surface life.
· Bearing is lightweight and thin (3 mm at its thickest), so it doesn't take up much space and has a compact design.
· Minimizes operating noise.- Volume Discount

FAQ Oil Free Bushings
- Question: What does the term ″self-lubricating bushing″ or oil free bushings refer to?
- Answer: The term ″self-lubricating bushing″ or oil free bushings 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 or oil free bushings 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 oil free bushings?
- Answer: Oil free 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.
