NF E 25-511 Conical Knurled Spring Washers, Symbol CS Alloy Steel 65Mn Dacromet

Characteristics:

1. Conical Design: The washer features a conical profile with a wider diameter at one end and a narrower diameter at the other. This design allows it to adapt to different sizes and shapes for assembly, while providing uniform pressure distribution.

2. Knurled Surface: The surface of the washer is knurled, creating a serrated or raised texture. This texture not only increases friction but also enhances the anti-slip properties of the washer.

3. Spring Properties: Conical knurled spring washers possess a certain degree of elasticity and flexibility, allowing them to compress and expand within a certain range. This characteristic enables the washer to adapt to minor variations during the assembly process, reducing vibration and noise.

Advantages:

1. Strong Anti-Slip Performance: The knurled surface increases the friction between the washer and the contact surface, effectively preventing slippage and loosening.

2. High Adaptability: The conical design and spring properties enable the washer to adapt to different sizes and shapes for assembly, while accommodating minor changes during the process.

3. Vibration and Noise Reduction: The elasticity and flexibility of the washer can absorb and dissipate vibration energy, thus reducing vibration and noise generated during equipment or structure operation.

4. Long Service Life: The knurled surface and spring properties give the washer high wear resistance and durability, ensuring stable performance over a long period of time.

Applications:

1. Automotive Manufacturing: Conical knurled spring washers are widely used in automotive manufacturing, such as in the assembly of engines, transmissions, suspension systems, and other components, to reduce vibration, lower noise, and improve assembly precision and stability.

2. Aerospace Industry: In the aerospace industry, where assembly precision and stability are crucial, conical knurled spring washers are used in the assembly of fasteners for aircraft, rockets, and other equipment to ensure safe and reliable operation.

3. Machinery Equipment: In various machinery equipment, such as machine tools, engineering machinery, agricultural machinery, and more, conical knurled spring washers are commonly employed in the assembly of fasteners to enhance the performance and stability of the equipment.

4. Construction Industry: In the construction industry, conical knurled spring washers are used in the assembly of fasteners for bridges, tunnels, steel structures, and other constructions to ensure the stability and safety of the structures.
