The Manufacturing Process of Bushing Bearings
Bushing bearings are constructed using a multi-layered composite material, with each layer serving a specific purpose to enhance performance and durability.
- Outer Layer: The outermost layer is crafted from SPCC elastic steel plating, providing robust support capable of withstanding forces up to 300kgf per square centimeter.
- Middle Layer: The middle layer consists of a lead bronze sintered layer, which roughens the surface of the SPCC steel and enhances the strength of the bearing through the inclusion of PTFE+ additives. This layer also facilitates efficient heat transfer to the machine wall via the copper component.
- Inner Layer: The innermost layer is a mixture of PTFE and lead, designed to minimize the friction coefficient and reduce friction to a minimum.

The Role of Butterfly Valves in Industrial Processes
Butterfly valves are essential for controlling the flow of fluids in pipelines. They are particularly popular due to their compact design, low cost, and ability to provide precise flow control. These valves consist of a disc, also known as a butterfly, which rotates around an axis to regulate the flow of fluids. However, to function effectively, butterfly valves require various components, including bearings.
Importance of Bearings in Butterfly Valves
Bearings play a critical role in the smooth operation of butterfly valves. They provide support and reduce friction between moving parts, allowing the valve to open and close with minimal effort. In high-stress industrial environments, choosing the right type of bearing is crucial to ensure optimal performance, longevity, and minimal maintenance requirements.
Stainless Steel Backed PTFE Bearings: A Winning Combination
Stainless steel backed PTFE (Polytetrafluoroethylene) bearings have gained widespread acceptance in butterfly valve applications due to their remarkable properties. This combination of materials offers several key advantages:
- Corrosion Resistance: Stainless steel is renowned for its exceptional corrosion resistance properties. When used as a backing material for PTFE, it protects the bearing from the corrosive effects of the fluids being transported, making it ideal for applications where corrosion is a concern.
- Low Friction: PTFE is well-known for its low friction coefficient, which results in reduced wear and tear on the bearing and valve components. This low friction contributes to the valve’s smooth operation and longer lifespan.
- High Temperature Resistance: Butterfly valves often operate in extreme temperatures, and stainless steel backed PTFE bearings can withstand a wide temperature range, making them suitable for both high and low-temperature applications.
- Chemical Compatibility: PTFE is highly resistant to a wide range of chemicals, ensuring that the bearings remain unaffected by the corrosive properties of various process fluids.
- Self-Lubricating: PTFE possesses self-lubricating properties, reducing the need for additional lubrication and maintenance. This not only saves on maintenance costs but also prevents contamination of the process fluids.
- Load-Bearing Capacity: Stainless steel backing provides the necessary structural support to handle the mechanical loads and pressures encountered in butterfly valve applications.
Applications of Stainless Steel Backed PTFE Bearings
Stainless steel backed PTFE bearings are widely used in various butterfly valve applications, including:
- Chemical Processing: These bearings excel in corrosive chemical environments, making them suitable for handling acids, bases, and other aggressive chemicals.
