TELESCOPIC SPRINGS STEEL COVER DETAILS
Materials
(click to enlarge)
Standard telescopic spring covers are made from high-quality blue spring steel strip (55-58 Rockwell) with rounded edges. Strength up to 1800 N/m2.
If regularly used with coolants of high water content, we recommend spring covers be made of stainless strip steel. However, due to the properties of this material, the spring force of these springs is less so that they cannot be made in all sizes. Please contact us for details.

Installation
(click to enlarge)
Telescopic spring covers can be installed either horizontally or vertically. To avoid "sagging", telescopic springs designed for horizontal use have a larger overlap of coils than those designed for vertical use, and their larger diameter should be located where the majority of chips will be encountered.
Due to their high initial torque, telescopic spring covers designed for vertical mounting always require a longer extension than horizontal spring steel covers, and their larger diameter should be at the top.

Flanges
CQM recommends the use of collar and pilot flanges on each end of a telescoping spring cover to allow for the spring to turn. The telescopic spring must be able to move freely to ensure maximum life and must NOT under any circumstances be fixed (by means of screws or rivets).
Operating Conditions
(click to enlarge)
CQM designs telescopic spring covers to allow for traveling speeds up to 40m/min. Telescopic springs find optimum operating conditions in an oily environment. They are not suitable for use where fine particles or dust are encountered. In the latter case we recommend the use of bellows.
Maintenance
Regular maintenance of conical spring steel covers is indispensable. Depending on the amount of soiling, the springs should be cleaned daily or weekly, followed by the application of a thin oil film in accordance with our maintenance instructions. A special spray can be supplied by us to ensure the longest life of your telescopic spring covers. Never GREASE telescopic springs!
