Product Explanation: Brass Bearing Bushing

Distinctive Features of the Product

1. Elimination of Oil Supply Systems, Injection Holes, and Groove Processing

• The omission of oil supply devices, along with associated costs for processing and assembly, drastically reduces manufacturing expenditures and time, contributing significantly to manufacturing cost reductions.

2. Diminishing Operational Costs

• Notably reduces the consumption of lubricating oil and maintenance expenses for the equipment, while also eradicating risks associated with insufficient oil supply.

3. Shortening Design Time

• The incorporation of oil-less technologies simplifies design and structural elements, lowers costs, saves design time, and enhances mechanical performance. Furthermore, the use of self-lubricating bearings can notably improve mechanical performance, extend lifespan, and elevate reliability.

4. Lubricating Oil Recovery and Environmental Protection

• The absence of waste oil recovery processes is beneficial for environmental protection. JDB (500#) self-lubricating bearings, as components in the mechanical industry, find usage in a broad sense. To ensure the smooth operation of mechanical transmission, considerable effort has been invested. Bearings are differentiated into rolling and sliding bearings. Under conditions like high-load motion, foreign object intrusion, temperature conditions, oil supply, and imperfect maintenance, general sliding bearings can cause fluffing. Under harsh conditions where general sliding bearings cannot be utilized, solid inlay metal self-lubricating bearings exhibit durability and resistance to fluffing, displaying the desired bearing performance, realizing high mechanical performance, and serving a maintenance-free function.

5. Usage Precautions

1. Use standard specifications in design wherever possible.
2. Ensure no foreign objects are present on surfaces during assembly.
3. Do not clean the sliding surface after use; the black or grey-black appearance due to the oil film formed by solid lubricants is normal—continue to use as is.
4. Applying lubricating oil to mating parts before assembly can shorten the run-in period and facilitate mechanical operation and rotation.
5. Press in slowly during assembly, strictly avoid hammering to prevent bearing damage and deformation.
6. Select appropriate materials for different parts during design to enhance mechanical performance and extend bearing lifespan.
7. Use screws for fixing in high load and reciprocating motion.
8. In fresh water, seawater, and maritime operations, it is recommended to use stainless steel or chrome-plated shafts for wear.

Advantages of Solid Self-Lubricating Bearings

1. Cost-Effective and Time-Saving Design

• The oil supply system in mechanical design is a laborious and time-consuming device. Using solid self-lubricating bearings in design eliminates the need to consider oil supply devices, saving on equipment costs. Moreover, the solid lubricating bearing can be designed in various shapes to meet the needs of various special occasions, and its use can significantly reduce mechanical maintenance and oil costs.

2. Operable Without Oil

• Since the linear expansion coefficient of the solid self-lubricating agent is higher than that of the metal matrix, the oil film will transfer to the mating part when the solid self-lubricating bearing starts to operate, realizing self-lubrication. Thus, it can be used in places where it is difficult to add oil and where oil or grease cannot be added, providing good lubrication even under low-speed, high-load conditions.

3. Lower Usage Costs

• Traditional mechanical design requires regular oil maintenance and checks on oil gauges and whether the oil supply device is unobstructed within a certain operating time. Periodic oil addition causes pollution to the body itself and the surrounding environment, increasing maintenance costs. Achieving self-lubrication not only achieves a clean environment but also significantly reduces the cost of using lubricating oil.

4. Superior Performance Under High Load and Low Speed

• Solid self-lubricating bearings are made of high-strength alloy brass cast by centrifugation as the matrix to bear the load, and graphite with good self-lubricating performance made of special formula as a lubricant to play a self-lubricating role. Therefore, it combines their respective advantages and can exert superior performance even under high load and low speed.

5. Superior Wear Resistance in Reciprocating Motion, Oscillating Motion, and Frequent Start-Stop Scenarios

• The principle of arranging lubricants for solid self-lubricating bearings is to ensure that all parts of the mating parts have lubricant effects during operation. Therefore, when arranging lubricants, the arrangement position of the lubricants must be determined according to the movement direction of the mating parts.

6. Product Cost is More Competitive

• Compared with similar products, it has a longer working life, requires little maintenance, has a long replacement cycle, and performs well.
