Bearing washer (Material: S45C / SUS304)
EPA

Washers, also known as washers, are parts that are usually used to pad between the connector and the nut.
The main purpose is as a spacer to protect the surface of the connected parts from being scratched by the nut, to disperse the pressure of the nut on the connected parts, and to reduce the detachment caused by vibration.
Common materials: steel, stainless steel, copper, aluminum, iron, plastic, titanium
Main application industries: industry, mold, equipment...etc
Washers can be divided into three types
1. Flat washer
Function: Prevent the surface damage of the connector, increase the contact area and disperse the pressure.
2. Spring washer
Function: used to flexibly prevent loosening and vibration.
3. Anti-loose washers
Function: To prevent the loosening of the connector and prevent the rotation of the screw.

A gasket is a mechanical seal between two objects, usually used to prevent pressure, corrosion, and pipeline leakage between the two objects.
Since the machined surface cannot be perfect, the irregularities can be filled with spacers.
Main use: sealing of pipe flanges, valves, pumps, pressure vessels, etc. some professional equipment
The main application industries are petrochemical, refining, electric power, metallurgy, manufacturing and other industries

This product is made according to DIN6340
