|
Bimetal side plates are a type of bearing that is commonly used in hydraulic gear pumps. These plates are constructed from two types of metal – typically a high-quality low carbon steel and a bronze alloy – through a process of high-temperature sintering and rolling.
These bimetal plates are designed to withstand high impact loads, making them suitable for use in hydraulic gear pumps which are often subject to intense forces. The plates’ combination of steel and bronze creates a bearing that is both strong and has excellent anti-friction properties.

| Function of SinoBronze ® Side Plates |
 |
|
In a hydraulic gear pump, SinoBronze side plates serve several crucial roles:
1. Efficiency: The main function of the side plate is to reduce friction in the gear pump, which helps maintain the pump’s operational efficiency. The plate’s bronze layer offers excellent anti-friction properties, ensuring that the gears in the pump can rotate smoothly and without unnecessary resistance.
2. Durability: The steel backing of the bimetal side plate provides strength and durability, allowing it to withstand the high pressures and forces commonly experienced in hydraulic systems.
3. Maintenance and lifespan: Thanks to their excellent wear resistance, bimetal side plates can extend the lifespan of hydraulic gear pumps. By reducing friction and wear, these plates help prevent premature wear and tear, reducing the need for frequent maintenance and replacement of parts. |
| |
In conclusion, bimetal thrust plates play a crucial role in the operation of hydraulic gear pumps. Their combination of strength, durability, and anti-friction properties make them an indispensable component, contributing to the overall efficiency and lifespan of the pump. It is essential to source these components from a reliable supplier to ensure the optimal performance of your hydraulic gear pump.
