FZF-5 copper-based inlaid self-lubricating bearings, also known as JDB bearings, are a type of self-lubricating bearing that uses metal as the base material. These bearings feature embedded solid lubricants within the metal surface, which help reduce friction and wear during operation.
During operation, the metal substrate supports the majority of the load, while the solid lubricant embedded in grooves or holes is transported to the contact surface. This creates a smooth, strong, and even layer that reduces friction and extends the life of the bearing. As the bearing operates, the solid lubricant continuously replenishes the contact area, ensuring long-term performance with minimal wear and noise.
Unlike traditional bearings that rely solely on oil films, these self-lubricating bearings offer high load capacity, excellent impact resistance, heat resistance, and a low coefficient of friction. They are particularly well-suited for heavy-duty applications where oil film formation is difficult, such as in low-speed, reciprocating, or vibrating environments. Additionally, they are resistant to water, acid, and other corrosive elements, making them ideal for harsh industrial conditions.
Key features of copper alloy inlaid self-lubricating bearings include:
1. Long-term operation without the need for oil or grease.
2. Excellent wear resistance and low friction, ideal for heavy-duty, low-speed operations.
3. Suitable for applications where oil films are hard to maintain, such as in reciprocating or intermittent motion.
4. Corrosion and chemical resistance, making them suitable for a wide range of environments.
5. Operable across a broad temperature range from -40°C to +300°C.
6. Low maintenance and long service life, reducing downtime and repair costs.
These bearings are widely used in industries such as metallurgy, mining, shipbuilding, gas turbines, and rolling equipment, where high loads, low speeds, and challenging operating conditions are common.
In addition to their durability and efficiency, users have reported significant energy savings and reduced fuel consumption. Compared to conventional bronze bushings, these bearings have double the hardness and more than double the wear resistance, making them a preferred choice for demanding applications.
Whether it's for continuous casting machines, train supports, or heavy machinery, copper alloy inlaid self-lubricating bearings provide reliable performance under extreme conditions.
