rubber Hardness 55° Shore.

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. * F_perm. is
the permissible static permanent load, which may be overlaid by a
dynamic, alternating load. With shearing load please take care that no
tension load in the rubber occurs at all during mounting. To achieve a
sufficient fatigue strength provide some compressive pre-stressing. The
stated permissible loads are only approximate, guideline values for the
static load for "medium" rubber hardness. With particularly high,
dynamic, alternating loads or high frequencies, the load figures have to
be reduced accordingly. Temperature resistant up to 80°C.
