What are axial joints and what are they used for?

Axial joints similar to DIN 71802 are mechanical linking elements that enable linear motion transmission along an axis. They are often used in linear drives, lifting systems, and any application that requires direct force transmission in an axial direction.

What are axial joints made of and what parts do they include?

An axial joint typically consists of an axial ball socket, the ball stud DIN 71803, a circlip, an optional sealing cap, a hex nut, and grease.

How do axial joints differ from angle joints according to DIN 71802?

The main difference lies in the direction of movement: axial joints transfer forces along a straight axis (180°), while angle joints transfer forces at an angle (90°).

What is the swivel angle of axial joints similar to DIN 71802 and what significance does this have for the application?

The pivot angle of axial joints, similar to DIN 71802, is ±18 degrees. This means that the joint allows for a total movable rotation of 36 degrees. Such a pivot angle ensures that the joint offers sufficient flexibility to compensate for axial movements and misalignment in applications. The pivot angle is particularly important to ensure that the joint remains intact despite unfavorable movements or forces and provides reliable power transmission.

What are the extraction forces of the ball stud from the axial ball socket in axial joints and what does this mean for the application?

The extraction forces of the ball stud, as they occur in axial joints similar to DIN 71802, range from at least 30 to at least 100 N depending on the size. These values indicate how much force is required to pull the ball stud out of the ball socket. These extraction forces are crucial for stability and safety, ensuring that the connection remains secure under normal operating conditions and does not unintentionally loosen, thereby guaranteeing safe power transmission and motion control.

What materials are used for axial joints?

Axial joints are available in steel, stainless steel, and stainless steel A4 quality. Each material option offers specific advantages in terms of corrosion resistance and load capacity.

What surface treatments are available for axial joints?

The surface treatments include bright and electroplated galvanised white.

What sizes and thread versions are axial joints available in?

The sizes range from 6 M4 to 19 M16. This includes various diameters and thread sizes to meet different application requirements. They are available with fine-pitch thread right, regular thread left, and right. For more precise adjustment options, a fine-pitch thread is best suited.

What are the specific applications for axial joints?

They are used in mechanical engineering, vehicle construction, agricultural and construction machinery, energy technology, and the manufacturing industry to ensure precise linear movements and power transmission.

What options are there for axial joints similar to DIN 71802?

Axial joints with sealing cap increase wear resistance and extend the lifespan of the joint, especially under adverse environmental conditions (dust, lubricants, etc.).

How do I correctly install an axial joint?

Clean all parts, check material compatibility, apply lubricant, use appropriate tools, and ensure the axial joint is mounted in the desired position.

What safety measures should be considered during the installation and use of axial joints?

Wear personal protective equipment, use appropriate tools, pay attention to mechanical stress, and conduct regular maintenance and inspections.

What standards must axial joints comply with?

Relevant standards include DIN 71802 (specifications for dimensions and technical requirements), DIN 71803 (important dimensions and technical details for the ball stud), DIN ISO 2768 (general tolerances), DIN EN ISO 9001 (quality management), and others for material and manufacturing accuracy.

How do you maximize the lifespan of an axial joint?

A suitable selection of material and surface protection, proper installation, regular lubrication and maintenance, as well as the use of sealing caps contribute to extending the lifespan.
