• Telescopic springs made of
  hardened high-grade spring
  steel ensure an excellent
  protection against dirt, swarf
  and mechanical damage even
  when fully extended
  
  
• Minimum overlap (of the
  individual windings) of 40%

• A special manufacturing method
  and optimal resilience ensure an
  easy compression and extension.
  Horizontal springs have a minimal
  sag and vertically used springs
  only a slight lateral deviation
  
  
• Winding-on types are available
  up to the size 54/1120/120
  
  
• Easy assembly by pushing the
  springs over the machine parts

 FEATURES:~ Telescopic springs made from hardened high-grade spring steel ensure an excellent protection against dirt, chips and mechanical damage even when extended. This good result is achieved with a minimum overlap of the windings of 40%, thus enabling the user to safely protect, for instance, high precision ball screws. A special manufacturing method ensures a minimal sag of horizontal springs and only a slight lateral deviation of vertically used springs. The optimal resilience of the springs assures an easy compression and extension. Assembly of the spring is easy. Normally, the springs are pushed over the edge of the spindle or shaft when mounting the machine parts. Upon request, 'winding-on' types are available for later assembly. Detailed information will be provided if required.

SUPPLY:~ Telescopic springs are available in a wide range of dimensions for various applications. For non-standard applications, Hennig supplies telescopic springs made to individual requirements. In order to provide an optimum protection for any kind of assembly, telescopic springs have different features for horizontal and vertical use. For special requirements such as extremely long travels or shorter compressed lengths, two standard telescopic springs can be combined. The many types of telescopic springs available are listed below in our 'easy-to-use' chart.
