Axial joints similar to DIN 71802

Axial joints, according to DIN 71802, are used as connecting and guiding elements for moving parts, providing corner joint functionality. While standard angle joints may not always meet the design requirements, especially when linear force transmission is needed, the axial joint offers a specialized solution. Unlike the 90° angular conversion of standard joints, the axial joint converts the absorbed forces into linear motion through a 180° variant. The allowable pivoting angle, similar to DIN 71802, is ±18°, and the withdrawal forces for the ball stud from the ball socket range between a minimum of 30 N and a maximum of 100 N, depending on the size.

Axial joints are available in steel and stainless steel, with dimensions ranging from M5 to M16. They can be obtained in bright or galvanized finishes, with or without sealing caps, as fully assembled units or as component parts, with or without hexagon nuts. Additionally, they can be acquired with a sealing cap and rivet stud.

Materials

  • Ball socket and stud: carbon steel
  • Alternative: stainless steel AISI303 (1.4305) ; stainless steel  AISI316L (1.4404)
  • Snap ring and safety clip: spring steel 60Si2MnA (C98 UNI EN 10270-1 DH); alternative: stainless steel
  • Gaiter: Neoprene

Surface treated 

  • Zinc plating white & blue passivate (silver/clear) according to EN ISO 4042
  • Chromate treatment (passivation) example on request 

Operating Temperature range

  • -40°C ~ +120°C (-40°F ~ +248°F)
  • -30°C ~ +110°C (-22°F ~ +230°F) (with neoprene protection cap)

Some current applications of axial joints include:

  • Bowden cable
  • Linkages
  • Remote controls
  • General machine construction

Delivery condition

The standard delivery of the axial joints similar to DIN 71802 made of carbon steel is without heat treatment. If higher strength is required, heat treatment angle joints can be ordered on request.

The tensile strength as below after heat treatment
• Ball socket: carbon steel, min. tensile strength Rm = 500 N/mm²
• Ball stud: carbon steel, min. tensile strength Rm = 600 N/mm², ball induction hardened on the surface with a ≥ 52 HRC hardness

Extraction and Insertion force ball-stud and ball-socket

The load values requested for the extraction and insertion of the ball stud from/to the ball socket’s housing with the mounted “R” spring, with the joint free from grease, are indicated in the following table:

d1 (ball diameter) 8 10 13 16 19
min. extraction force [N] 30 40 60 80 100
max insertion force [N]  200 250 320 350 400

 

Permissible load and tightening torque

The maximum permissible load for the axial joint is given in the following table; it is also important to tighten the nut as indicated:

Designation Permissible load [N]  Nut tightening torque [N·m] 
static dynamic
8 M5 50 20 3.5
10 M6 100 40 7.4
13 M8 200 80 18
16 M10 400 160 35
16 M12 400 160 35
19 M14 800 320 70
19 M16 800 320 70

Some current applications of axial joints include:

  • Bowden cable
  • Linkages
  • Remote controls
  • General machine construction
