Hard rubber-attachment element for use in e.g. construction industry, has sliding core manufactured from aluminum and steel alloy and including loading area, whose length is one-third of total length of cylindrical part

摘要

The attachment element has a sliding core, which is manufactured from aluminum and steel alloy. The attachment unit includes a loading area, in which torsional loading occurs, a load-free area, and hole opening area. The length of the loading area is one-third of the total length of a cylindrical part of the attachment unit. The tolerance and dimension of the core is selected such that a smooth contact is ensured.
