Extension Spring with Turnable Bolt, Outside Diameter 30mm, Free Length 330mm, Metrol - 6388

Extension springs with turnable, extra strong loops for high loads In order to be able to use the spring to its maximum, without running the risk of loop breaks, you can use this series of extension springs with hardened loops, which have tapered ends. The loops are loose, and can therefore be turned to any position.

Max load length and temperature Maximum load length Ln applies for static or pseudo static loaded springs operating at temperature up to about 40° C. The relaxation, i.e. the power loss over time, will then stay within acceptable values for most applications. At higher operating temperatures or dynamic life demands, more than 10,000 cycles, the spring should not be loaded as far as Ln. Maximum permitted operating temperature of unalloyed spring steel EN10270-1-SH is about 120 °C.
