Material: High-quality blue spring steel strip (55-58 Rockwell) with rounded edges. Strength up to 1800 N/m². Standard telescopic springs are designed for speeds up to 40 m/min.
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.
Horizontal mounting position:
telescopic springs designed for horizontal use have greater overlap of coils than springs for vertical use to avoid "sagging". The larger diameter should be where most chips occur.
Vertical and diagonal mounting position:
due to the high extension forces involved, these springs (which act against the force of gravity) require greater extended length than horizontal telescopic springs. The larger diameter should be at the top. This avoids dirt from falling into the coils and has a self-cleaning effect.
Centering should be provided at the ends of the springs to allow these to turn. The springs must be able to move freely and must not be fixed. The mounting sleeve and centering flange are not normally supplied with the springs.
These flanges can be supplied as optional accessories.
Types and Sizes:
Presently we have more than 1000 different standard sizes available. In our catalog you can find all technical data of the telescopic springs in our itemized list. This type code results in our final order number.
You'll find a wide range of telescopic springs in our online shop.
