distinct from other flexible couplings, the new
generation of NENFLEX spiders, the star
shaped, the Wrap-Around and the individual free
floating are the subject matter of a patent and
a result of CAD analysis and practical dynamic
test. The specially designed profile of the spider
arm and the drive insert allows only a partial
contact with the driver and the driven jaws at
no load and 100% contact at nominal torque. There
is less abrasion and heat build up which enhances
the service life of the spider and also allows
a larger load carrying capacity.
variety of high performance polyurethane materials
are available as optional materials for the spiders
and drive inserts.
