When it comes to precision cutting applications, the quality of components used can significantly impact the accuracy, efficiency, and longevity of the cutting process. Among these components, sliding strips, self-lubricating wear plates, and bushing housings play a crucial role.
Sliding strips, often made of high-grade materials like stainless steel or hardened alloys, provide a smooth and consistent surface for the cutting tool to slide against. They are designed to minimize friction and wear, ensuring precise and repeatable cuts.
Self-lubricating wear plates are an innovative solution for reducing friction and wear in cutting applications. These plates are typically embedded with solid lubricants that release lubricating oils or greases during operation, creating a lubricating film between the sliding surfaces. This film helps reduce friction, heat generation, and wear, improving the overall performance of the cutting tool.
Bushing housings, also known as bearing blocks, house the bushings or bearings that support the rotating components in a cutting machine. These housings are precision-manufactured to ensure accurate alignment and stability of the bushings. They often feature hardened surfaces and wear-resistant materials to ensure long-term durability and performance.
In precision cutting applications, the combination of sliding strips, self-lubricating wear plates, and bushing housings can significantly enhance the cutting process. By reducing friction, wear, and heat generation, these components help maintain the accuracy and efficiency of the cutting tool over extended periods of operation.
It's essential to select components that are specifically designed for precision cutting applications and are manufactured to the highest quality standards. With the right combination of sliding strips, self-lubricating wear plates, and bushing housings, you can ensure your cutting process is as precise, efficient, and reliable as possible.

This material meets the demanding criteria for long life and trouble-free performance with or without lubricant, of high safety factor even.
The bronze backing provides a high corrosion resistance, anti magnetic properties and a good thermal conductivity, The bearings are particularly appropriate for high temperature environment where no oil is efficient and the machine must be under successive long period working condition.
The typical applications covered Steel metallurgy industry such as bushes for roller grooves of successive casting machines, cement grouting pumps and screw conveyers for cement and so on.
