S2 Belt Fasteners

Jingwei’s S2 belt fastener is engineered through an advanced forming technique that combines integral stamping with welding, resulting in a highly robust structure. Made from galvanized carbon steel, this fastener is designed to withstand harsh environmental conditions with enhanced corrosion resistance. The S2 model stands out with its exceptional tensile strength, capable of handling up to 1000 KN/m, which supports more demanding applications compared to many other fasteners. It is equipped with a collet that measures 45mm in width and 68mm in height, providing a reliable grip on the conveyor belt. A key feature of the S2 is its extended bolt length of 120mm, which offers deeper engagement for increased stability and security in high-load scenarios.


Ideal Usage Scenarios

The S2 belt fastener is tailored for heavy-duty industrial environments where conveyor belts endure high stress and significant wear and tear. This fastener is especially effective in industries such as mining and construction, where the belts must handle extreme loads and the fastening system must maintain its integrity under intense operational demands. Additionally, its robust design makes it suitable for applications in the heavy machinery sector, where prolonged durability and reliability are critical.

Applications and Benefits

The integration of the S2 belt fastener into conveyor systems translates to enhanced operational efficiency and reliability. Its unique construction, featuring a longer bolt and a blend of stamping and welding, provides a superior hold that reduces the risk of mechanical breakdowns. This reduction in potential failures minimizes downtime and maintenance costs, crucial in sectors where operational continuity is key. The use of galvanized carbon steel not only ensures longevity but also reduces the frequency of fastener replacements, providing a cost-effective solution for managing high-performance conveyor systems.

S4 and S5 Belt Fasteners

Jingwei’s S4 and S5 belt fasteners distinguish themselves through their advanced precision casting process, which involves three distinct parts, enhancing their structural integrity and durability. Both models are available in two material options: galvanized cast steel for standard applications and stainless steel for environments requiring higher corrosion resistance.

The S4 belt fastener boasts a strength capacity of up to 1200 KN/m, making it suitable for heavy-duty operations. It features a collet width of 48mm and a height of 72mm, dimensions that ensure a robust and secure fit.

In comparison, the S5 belt fastener is designed for even more demanding applications, with a maximum strength of 1600 KN/m. It shares the same collet width of 48mm but has a slightly taller height of 75mm, providing extra grip and strength that are critical in high-load environments.

Ideal Usage Scenarios

The S4 fastener is ideally suited for industrial sectors such as manufacturing and processing where reliable fastening is essential but not to the extremes of more harsh environments. Its robust design and material choice make it a dependable option for a wide range of applications.

The S5 fastener, with its superior strength, is particularly effective in industries like mining, heavy construction, and any applications involving extreme mechanical stresses where its high performance can prevent slippage and extend the operational life of conveyor systems.

Applications and Benefits

The unique precision casting of the S4 and S5 belt fasteners ensures that they provide excellent load distribution across the belt, reducing the risk of belt damage and prolonging the belt’s life. The choice between galvanized cast steel and stainless steel allows for customization based on environmental conditions, ensuring optimal performance and durability.

The S4 and S5 models offer improved operational reliability, with their enhanced specifications designed to handle higher and more intense loads. This capability helps minimize downtime and maintenance interventions, crucial in high-stakes industrial settings. Furthermore, the advanced material engineering promotes longer service life, resulting in cost savings from reduced replacement frequency and lower inventory costs.

These descriptions underscore the tailored applications and benefits of Jingwei’s S4 and S5 belt fasteners, highlighting their suitability for different industrial requirements and environments. Each fastener model is crafted to provide secure, reliable, and durable solutions to meet the demanding needs of various heavy-duty conveyor applications.
