Material: Metal parts: Stainless steel 1.4301 (AISI 304).
Elastomer: Natural rubber, 55° Shore hardness.

Rubber-Metal buffers are simple, reasonably priced standard components
used for elastic mounting. When shearing load occurs their load-bearing
capacity is considerably lower than with pressure load. This has to be
considered when horizontal mass forces or belt traction occur. The grade
of rubber used has perfect physical properties. Temperature resistant up
to 80°C.
