The easy handling facilitates mass assembly, which is especially valuable in industrial production. Dismantling is easy and can be done with a screwdriver, for example.

High retention force and reliability: Due to their special design, the locking washers DIN 6799 generate excellent retention force, effectively holding the components in place. This retention force remains even under demanding conditions and vibrations, ensuring a secure and reliable connection. This feature is particularly important in applications where safety and functionality are prioritized.

Durability and maintenance-free: Made from high-quality materials such as spring-hardened steel or stainless steel, the locking washers DIN 6799 offer excellent durability and corrosion resistance. These features ensure that the washers maintain their functionality even under continuous use in aggressive environments without the need for replacement or maintenance. This minimizes operating costs and increases the reliability of applications.

Improved safety: The design and functionality of the locking washers help to minimize the risk of unintentional loosening of components. This improves the overall safety of machinery and equipment, helping to reduce potential hazards for users and the environment.

5. Assembly and Installation

Step 1 - Preparation: First, ensure that the axle or bolt on which the locking washer DIN 6799 is to be installed is free of dirt, oil, and other contaminants. This guarantees optimal holding force of the locking washer DIN 6799.

Step 2 - Positioning: The locking washer DIN 6799 should be positioned in the correct orientation to the groove on the axle or bolt. Make sure that the embossed edge of the washer is correctly aligned to allow proper snapping into place.

Step 3 - Installation: Now, carefully but with sufficient pressure, press the locking washer DIN 6799 into the groove of the axle or bolt. The installation can be done with or without an assembly tool, but using the special assembly tool simplifies the process. The procedure is complete when the locking washer DIN 6799 is fully snapped in and flush with the surface of the groove base.

Step 4 - Verification: After installation, it is recommended to check the locking washer DIN 6799 for correct fit and full engagement. A properly installed locking washer DIN 6799 will be firmly in place and cannot be removed without applying targeted force.

6. Accessories and Extensions

For the locking washer DIN 6799, a specific assembly tool is available to facilitate installation in hard-to-reach areas.

Frequently Asked Questions (FAQ)

What is the locking washer DIN 6799 and what is it made of?

It has a minimalist yet functional design that offers excellent retaining force for lightly to heavily loaded connections, while ensuring durability and reliability.

For which applications is the locking washer DIN 6799 particularly suitable?

The locking washer DIN 6799 is used in a wide range of industries and applications. These include mechanical and plant engineering, agricultural equipment, and various everyday applications such as household appliances and bicycles. Its robustness and reliability make it the preferred fastener in many critical applications.

What are the advantages of the locking washer DIN 6799?

The advantages include easy and quick assembly, high holding power and reliability even under demanding conditions, durability and maintenance-free operation due to the use of high-quality materials, as well as improved safety by minimizing the risk of unintended loosening of components.

How is the assembly of the locking washer DIN 6799 carried out?

The assembly is carried out in several steps: First, the axle or bolt on which the locking washer is to be mounted is cleaned of dirt or impurities. Then, the locking washer is correctly positioned and pressed into the groove, with special assembly tools possibly facilitating the installation. After installation, it is recommended to check for correct fit and full engagement.

Why is it important to regularly inspect locking washers DIN 6799 and what measures should be considered during care and maintenance?

Regular inspection is important to ensure the safety and functionality of the locking washers. Attention should be paid to signs of corrosion, wear, or damage that could impair their function. In extreme operating environments, more frequent inspections are advisable to detect damage early and renew or replace the locking washers if necessary, ensuring a permanent and stable connection between the components.

What materials are used for the production of locking washers DIN 6799?

For the production of locking washers DIN 6799, spring steel and stainless steel are usually used. Spring steel is appreciated for its high elasticity and hardness, which ensure permanent clamping force. Stainless steel is preferred for its corrosion resistance and durability in environments with aggressive media or where there are high hygienic requirements.

How do you determine the size of the locking washer DIN 6799 for a specific application?

The size of the locking washer is typically determined by the diameter of the bolt or shaft on which it is to be mounted. It is important to accurately measure the outer diameter of the shaft or bolt and choose a locking washer with an inner dimension slightly below this measurement to ensure a secure and tight fit. Additionally, the groove width and depth in the shaft or bolt should match the specifications of the locking washer.
A great help for the proper design of the groove or indentation is the mbo Osswald bolts configurator with groove.

Can locking washers DIN 6799 be reused?

Although locking washers DIN 6799 can be carefully removed and theoretically reused in some cases, this is not recommended. The disassembly process can alter the structure of the locking washer and impair its holding force. It is advisable to always use new locking washers for critical applications or when permanent and reliable holding force is required.

What is the significance of locking washers DIN 6799 for the general safety of machinery and equipment?

Locking washers DIN 6799 play an important role in ensuring the overall safety of machinery and equipment.
