  • Application Details

    *Dynatect will recommend another type of protective cover for your application.
    Standard telescopic springs are designed for speeds up to 40 m/min (26.25 in/sec). For higher speeds, Dynatect can provide other options like bellows, way covers, and shade rollers.

  • Cover Sizing

    Fill out what you know, we can help you with the rest.

  • If part number not known, supply the remaining dimensional information and we will make a recommendation.

    If you have already selected the part number, then we do not need the dimensions below.

  • part = Cylinder, shaft, spline, lead screw, ball screw, etc.

  • *Horizontal & diagonal mounting positions: Telescopic springs designed for horizontal use have greater overlap of coils than springs for vertical use to avoid “sagging”. *Horizontal mounting position: Telescopic springs designed for horizontal use have greater overlap of coils than springs for vertical use to avoid “sagging”.

    **Vertical mounting position: These springs have greater extended length than horizontal springs. The larger diameter (D2) should be at the top/higher mounting position. This avoids dirt from falling into the coils and has a self-cleaning effect.

  • For L max refer to size chart and diagram #2 below

  • Preferred Material

  • High-quality blue spring steel strip [55-58 Rockwell] with rounded edges. Strength up to 1800N/m².

    Where coolants with a high water content are regularly used, we recommend telescopic springs made of stainless steel (material No.1.4.310). These, however, have less spring force and can therefore not be made in all sizes.

    Available stainless-steel springs are highlighted yellow in our list of spring types.
