Telescopic Spring Guards

Telescopic Spring Guards

Telescopic springs – also known as spiral springs or spring guards – have been developed to protect against accidents and mechanical damage wherever there are rotating parts, such as spindles or shafts. They are designed to follow the motion of the machine by spring force. Some of these springs can also be retrofitted.

  • Sizes: Presently, more than 1000 different standard sizes are available. See literature for sizes.
  • Material: High-quality blue spring steel strip (55-58 Rockwell) with rounded edges. Strength up to 1800 N/m². Thickness of 0.6 mm
  • Speed: Standard telescopic springs are designed for speeds up to 40 m/min.
  • Mounting/Orientation: Centering Flanges/ Collars which should be provided at the ends of the springs. They may be used for vertical, horizontal or diagonal motion. See tab below for more info.

Application Notes:

  • Intended to cover a spindle or ball screw on a machine tool. Compatible with oil.
  • Abrasive particles tend to find their way between the coils. Therefore, for grinding dust, we recommend a fabric bellows cover as an alternative method of protection.
  • Where coolants with a high water content are regularly used, we recommend telescopic springs made of stainless steel. These, however, have less spring force and can therefore not be made in all sizes.
