A pin washer GOST 9649-78 is a specialized type of washer used to increase the bearing surface on a part in pin joints. It has a greater thickness compared to ordinary washers and provides a more secure fastening. Typically, it is installed together with a pin (axle) in a hole of a part. This allows for even distribution of the load and prevents wear of the parts.
Material and Characteristics
- Material: Usually made of steel, providing high strength and durability.
- Accuracy class A: This means that the washer has a high manufacturing accuracy, which is important for ensuring a reliable connection.
- Coating: Zinc plating is often used for corrosion protection.
- Dimensions: The inner diameter (for the pin), outer diameter, and thickness are regulated by ГОСТ 9649-78.
Application
Pin washers are widely used in various industries, including:
- Mechanical engineering: In assemblies and mechanisms where reliable part fixation is required.
- Automotive industry: In suspension, steering, and other assemblies.
- Agricultural machinery: In pin joints.
Advantages of using GOST 9649-78 pin washers
- Reliability: Provides a strong and durable connection.
- Ease of use: Easy to install.
- Availability: Wide range of sizes and materials.
- Compliance with standards: Manufactured according to the state standard, which guarantees quality.
GOST 9649-78 pin washers are an indispensable fastening element in many industries. Due to their characteristics, they ensure reliability, durability, and precision of connections.
