Contact SupplierStandard telescopic spring covers are made from high-quality blue spring steel strip (55-58 Rockwell) with rounded edges. Strength up to 1800 Nm2.
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.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.
