JDB650 copper-based inlaid self-lubricating bearings: no oiling required, completely self-lubricating

JDB650 copper-based inlaid self-lubricating bearings

JDB650 copper-based inlaid self-lubricating bearings are high-performance sliding bearings that combine the wear resistance of copper alloy (ZCuZn24Al6) and the self-lubricating properties of solid lubricants, so that they do not require oiling and maintenance during use
Basic characteristics and technical indicators

• Maximum load: The maximum static load capacity of JDB650 copper-based inlaid self-lubricating bearings is 250N/m², while the maximum load capacity at low speed is 100N/m²
• Using temperature: The operating temperature range of this bearing is very wide, from -100℃ to +300℃
• Maximum linear speed: The maximum linear speed is 2m/s under grease lubrication conditions, and can reach 4m/s when continuously lubricated
• Friction coefficient: The friction coefficient is between 003 and 020, which helps to reduce energy consumption and improve mechanical efficiency

Material Type and Performance Comparison

• Material Composition: The JDB650 series includes a variety of material types, such as extra-hard high-strength brass, aluminum bronze, etcDifferent materials have different hardness and elongation to adapt to different application environments
• Thermal conductivity: All types of JDB650 bearings have a thermal conductivity of 60W (m·K)⁻¹, which helps to effectively dissipate heat
• Expansion coefficient: The linear expansion coefficient varies from 16x10⁻⁶K⁻¹ to 19x10⁻⁵/℃ depending on the material, which is very important for applications under different temperature conditions
• Tensile strength: The range of tensile strength and hardness provides options for different load requirements, ensuring the reliability and durability of the bearing
  Self-lubricating mechanism and advantages
• Working principle: JDB650 bearings form a transfer film of solid lubricants on the bearing surface in the initial operation stage, and finally form a solid lubricating film to achieve self-lubrication
  No need for additional lubrication: This design allows the bearing to operate without oil or less oil without an additional lubrication system, reducing maintenance costs and system complexity
  

Application fields and applicable occasions

• Industrial applications: JDB650 bearings are widely used in high temperature, high load, low speed and heavy load occasions such as metallurgical continuous casting machines, train brackets, and steel rolling equipment
• Special environmental adaptability: Due to its self-lubricating characteristics, JDB650 bearings are particularly suitable for places where it is difficult to add oil or grease, such as dusty environments or underwater applications
  

Installation and maintenance

• Ease of installation: The design of JDB650 bearings takes into account the convenience of installation, simplifies the assembly process, and reduces the possibility of installation errors
• Low maintenance requirements: Due to its self-lubricating characteristics, JDB650 bearings have low maintenance requirements, which can significantly reduce machine downtime and maintenance costs

In general, JDB650 copper-based inlaid self-lubricating bearings have become the first choice for many industrial applications due to their excellent performance, wide application fields and low maintenance requirementsDuring the selection and use process, please consult the professional manufacturer Zhejiang Mingxu Machinery Manufacturing Co, LtdUnder the guidance of professional manufacturers, understanding its performance characteristics and maintenance requirements will help maximize its performance and extend its service life
