In the realm of metallurgical continuous casting, the machine train support system plays a crucial role in ensuring the smooth and efficient operation of the entire casting process. Among the various components that make up this system, high-force brass bushings stand out as a key element due to their unique properties and functions.
High-force brass bushings are designed to withstand the extreme forces and temperatures encountered during the continuous casting process. Made from a high-grade brass alloy, these bushings exhibit excellent strength, wear resistance, and thermal stability. This allows them to effectively support and guide the moving parts of the machine train, ensuring precise alignment and reducing the risk of misalignment or damage.
The use of brass as the primary material for these bushings is due to its exceptional combination of properties. Brass is a copper-zinc alloy that offers excellent machinability, ductility, and corrosion resistance. These qualities, combined with its high strength and wear resistance, make brass bushings ideal for applications in the metallurgical industry.
In addition to their material properties, high-force brass bushings are also designed with precision and attention to detail. The bushings are manufactured to exact specifications, ensuring that they fit perfectly within the machine train support system. This precision fit not only improves the overall performance of the system but also reduces the need for maintenance and repairs.
Overall, high-force brass bushings are an essential component of the metallurgical continuous casting machine train support system. Their unique properties and precision design ensure that the casting process runs smoothly and efficiently, minimizing downtime and maximizing productivity.
The VSB-JDB-1 solid mount bearing is located in a brass matrix. A high performance solid lubricant with solid graphite or MoS2 lubricants that interrupts the general lubrication of the bearings with limitations of the oil film. In the process of use, through the heat of friction to make the lubrication solid and the friction of the shaft, the formation of oil, the co-lubrication of the powders in excellent conditions.Its hardness is higher than average copper sleeve one times, wear-resisting property is also one times.At present, the product has been used in metallurgical continuous casting machine, train support, steel rolling equipment, mining machinery, ships, gas turbines and other high temperature, high load, low speed heavy load and other occasions.

| Shaft | Chamfer 5 mm x 15°, for easy insertion of the shaft | ||
| For smaller diameters, the OD should be greased before pressing in. | |||
| For larger diameters dry ice for freeze fitting should be used. |

1.No need of oil supply device, oil injection hole, oil tank processing oil supply device cost, processing cost, assembly cost and other excess costs and time savings, can significantly reduce the manufacturing cost.
2.The reduction in operating costs significantly reduces the amount of lubricating oil used and the cost of equipment maintenance, and also eliminates the risk of insufficient oil supply.
3.Shortening of design time oil-free can greatly simplify the design and structure, reduce the cost and save the design time. In addition, the use of self-lubricating bearings can also improve the mechanical properties, prolong the service life and improve the reliability and other aspects of significant results.
4.Oil recovery and environmental protection without waste oil recovery treatment, conducive to environmental protection.VSB-JDB(500#SP) self - embellishment bearing as a mechanical industry parts, has a certain sense of use.A lot of work has been done to make the mechanical drive run normally.The bearings are divided into rolling bearings and sliding bearings.General sliding bearing in high load mode of motion, foreign matter mixing, temperature conditions, oil supply, maintenance is not perfect, will cause hair.Under the harsh condition that such a general plain bearing cannot be used, the solid inlaid metal self-lubricating bearing's wear resistance and hair resistance can give play to the due performance of the bearing and realize the role of high performance and maintenance free of machinery.
