Spring washers with cap

1. Product description

Spring washers with cap serve as retainers for axles, bolts, and shafts without groove, by providing reliable axial protection. Made from high-quality spring steel or stainless steel (the cap is always stainless steel), they effectively prevent axial withdrawal on bolts and shafts. Thanks to their domed inner shape with several slots, they have spring properties that exert pressure in the clamped state when applied to the shaft or bolt, thereby fixing the parts securely. Our range includes spring washers with cap for shaft diameters from 1.6 to 25 mm, suitable for various industrial applications.

Spring washers with cap offer several advantages over the version without cap, by better protecting the washer and components in demanding environments from external influences and extending their lifecycle. Additionally, they reduce the risk of injury through covering sharp edges, which is particularly advantageous in work environments where regular maintenance is needed. The mounting is straightforward and requires only minimal preparation. To simplify installation, special assembly tools are available, enabling precise and time-saving installation.

3. Application Areas & Compatibility

Fields of application

Mechanical engineering: Spring washers with cap are frequently used in machinery to reliably secure components and prevent axial movements, with the cap providing additional protection against external influences.

Automotive engineering: In vehicle technology, spring washers with cap are used to secure shafts, axles, joints, or control mechanisms.

Agricultural and construction machinery: In heavy agricultural and construction machinery, spring washers with cap extend the lifespan of components under high stress due to their robust protection.

Electrical engineering: Spring washers with cap are used to secure electrical connections and fix mechanical parts in electrical devices, especially in applications without grooves.

Compatibility

Material of the bolt or shaft: The choice of material for spring washers with cap is important to ensure both mechanical security and protection against corrosive environments; stainless steel is often recommended.

Diameter: The spring washer with cap must match the diameter of the shafts or bolts to perform the desired securing and protective functions.

Axial load: Spring washers with cap must be suitable for the respective axial load, and the type of cap should be chosen to provide additional protection without compromising functionality.

Operating temperature: For extreme temperatures, the material of spring washers with cap must be resistant to ensure their protective function is not compromised.

4. Advantages and Benefits

Advantages

Easy installation: Spring washers with cap are easy to install and do not require any special grooves or other elaborate preparations on the shaft or bolt.

Cost efficiency: Due to their simple design and additional protection through the cap, they offer a cost-effective solution for securing components and protecting the environment.

Corrosion resistance: Spring washers with cap made of stainless steel are characterized by their high corrosion resistance and are thus ideal for use in humid or corrosive environments.

Versatility: They are available in various sizes and materials, making them suitable for a wide range of applications and environments. The cap provides an additional protective function.

Low maintenance: Spring washers with cap require little maintenance and their robust materials protect against wear, thereby extending their lifespan.

Protection for people: The cap covers sharp edges, reducing the risk of injury during handling or near moving parts.

Benefits

Effective axial securing: They reliably prevent axial displacement of components on shafts or bolts, thus increasing the operational safety of machines and equipment.

Protection against loosening: Spring washers with cap reduce the risk of unwanted loosening of connections, which is particularly crucial for applications with vibrations or dynamic loads.

Space-saving: By directly mounting onto the shaft or bolt, spring washers with cap require little additional space, making them ideal for tight or complex constructions.

Diverse applications: Thanks to their adaptability and the additional protection provided by the cap, they can be used in various industries.

5. Assembly and Installation

Selection of the right spring washer with cap: Choose a spring washer with cap that matches the diameter of the shaft or bolt. The inner diameter of the washer should be slightly smaller than the diameter of the bolt or shaft to ensure a firm fit. Ensure that the washer is made of a material suitable for the specific environmental conditions, especially in corrosive influences or high temperatures. The cap (always made of stainless steel) offers additional protection and can also reduce the risk of injury from sharp edges.

Preparation of the mounting surface: Ensure that the surface of the shaft or bolt is clean and free of dirt or lubricants, as a clean surface ensures optimal friction resistance.

Positioning: Place the spring washer with cap at the end of the shaft or bolt so that the curved inner part of the spring washer rests evenly and the cap covers the end of the shaft. Ensure that the spring washer exerts axial pressure on the adjacent components to ensure their secure fixation.

Compression: Position the adjacent components as desired and apply even pressure to compress the spring washer and push it onto the shaft or bolt. This pressure must be sufficient to create a firm connection without permanently deforming and damaging the washer. Ensure that the cap limits the possible push-on depth (measure T).

Check for a secure fit: After assembly, ensure that all parts are firm and secure. Ensure that the pressure is evenly distributed over the entire contact surface of the spring washer and that the cap sits correctly. If necessary, perform a functional test in which dynamic and static loads are simulated to confirm the secure attachment.

Proper assembly not only ensures optimal function and longevity of the spring washer with cap but also contributes to the overall safety and increased protection of the application.

6. Safety instructions & Standards

When using spring washers with cap on axles, shafts and bolts without groove, it is crucial to observe both safety precautions and applicable standards to ensure safe and compliant use. Below are some essential safety instructions:

Quality control: Use only spring washers with cap that are defect-free upon visual inspection. Especially for critical applications, the cap should have a flawless surface quality to ensure optimal protection.

Mechanical stress: Avoid overloading the spring washers with cap. Damaged or severely deformed washers or caps do not provide the necessary securing or protective effect and should be replaced immediately.

Corrosion protection: For applications in moist or aggressive environments, you should use spring washers with cap made of corrosion-resistant materials like stainless steel to avoid failure due to rust. An intact cap provides additional protection against environmental influences, as it is always made of stainless steel.

Regular inspection: Regularly check the spring washers with cap for wear or damage, especially in applications with strong vibrations or dynamic loads.

Use of Suitable Tools: Use appropriate tools for assembly and disassembly to prevent damage to the spring washers with cap and adjacent components. Ensure that the cap remains intact during tool use to maintain its protective function.
