Metal on one side only. Metal bumpers can be used to limit bearing
surfaces e.g. for elastically mounted power units, and as bump stop to
limit the spring travel in vehicles. They can also be used for machines
that cannot be fixed to the floor or are standing on floors with an
easily damaged surface, e.g. office machines. Temperature resistant up
to 80°C.
