Roller guides simplify the

welding of wind turbine towers

A collaboration between NSK and Spain-based Talleres Ganomagoga has led to a

major advance in the welding of wind turbine towers. Based on the latest NSK
roller guide technology, innovative linear motion solutions are allowing Talleres
Ganomagoga to achieve smooth and accurate movement of its welding machines
as the towers increase in length during production.
he Ganomagoga Group,
which has history stretching
back to 1974, has its
Theadquarters in Pontevedra,
in the Galicia region of northwest
Spain. Initially formed to serve sectors
such as marine, automotive and
construction, recent years have seen a
number of emerging industries come
to the fore, including renewable
energy and, specifically, wind power.
Talleres Ganomagoga specialises
in the manufacture of critical
assemblies for wind turbines,
including towers. Due to their size, the
towers comprise a number of
individual cone segments that the
company subsequently welds
together. Precision and repeatability
are prerequisites in this process,
which is why Talleres Ganomagoga
relies on linear roller guide technology
from NSK.
The company uses large welding
machines based on a column and
