JDB-600 cast bronze self-lubricating bearing details: choice for high-load applications

JDB-600 cast bronze bearings are a high-quality, self-lubricating bearing material, mainly used in mechanical scenarios with heavy loads and low-speed movement. Due to its excellent wear resistance and pressure resistance, it is widely used in engineering machinery, mining equipment, lifting machinery and other occasions that need to withstand high loads.

1. Material properties
JDB-600 bearings are made of high-strength cast bronze materials, and the self-lubricating effect is enhanced by the design of lubrication holes distributed on its surface. These holes are usually filled with solid lubricants, such as graphite or molybdenum disulfide, to form a uniform lubricating film on the contact surface of the bearing and the shaft.

Main material properties:

High strength: Bronze materials have excellent tensile strength and impact resistance, and can maintain structural stability under high load conditions.
Wear resistance: Cast bronze materials have high surface hardness and low friction coefficient, which reduces friction and wear.
Self-lubricating property: The distribution of solid lubricants enables the bearing to maintain low friction performance under dry sliding or low lubrication conditions.

2. Structural design
JDB-600 cast bronze bearings are usually made by centrifugal casting, which can improve the density and uniformity of the material. There are regular lubrication holes or grooves on the surface, and by filling solid lubricants, the bearings can be maintenance-free for a long time in practical applications.

Lubrication hole design:

The lubrication holes are usually distributed in a "plum blossom" or "diamond" shape, which helps to evenly distribute the lubricant.
The solid lubricant filled in the lubrication hole is gradually released during the friction process, which can effectively reduce friction and wear.
Hole and groove shape: For better lubrication and heat dissipation, JDB-600 bearings often use specific hole and groove shapes, such as hemispherical or shallow grooves. The design of these hole and grooves can help the lubricant to be evenly distributed on the friction surface.

3. Application advantages
Compared with traditional sliding bearings, JDB-600 cast bronze bearings have significant advantages in the following aspects:

Excellent self-lubricating performance: The presence of solid lubricants ensures that the bearings can still work stably in the absence of oil lubrication.
High load bearing capacity: Suitable for high load and low speed occasions, and can withstand large static and dynamic loads.
Long service life: The corrosion resistance and wear resistance of bronze material, combined with the self-lubricating properties, enable the bearing to operate for a long time in harsh environments.
Maintenance-free: Due to its self-lubricating properties, there is no need to add lubricating oil frequently, which reduces maintenance costs.

4. Application scenarios
JDB-600 cast bronze bearings are mainly used in the following fields:

Engineering machinery: Such as excavators, loaders, etc., under high load and heavy friction conditions, this bearing can provide good self-lubricating performance and high durability.
Lifting equipment: The rotating parts, shaft pins and other parts of lifting equipment such as cranes require high load capacity and long-term lubrication.
Mining equipment: In mining machinery, due to the harsh environment and high dust, the corrosion resistance and maintenance-free characteristics of JDB-600 bearings are particularly important.
Agricultural machinery: In agricultural machinery that needs to withstand long-term high-intensity work, the long life and low maintenance requirements of JDB-600 bearings make it an ideal choice.
