Disc Springs for Heavy Bolt Section |
 |
These series of Disc Springs have been specifically
designed for heavy bolted sections such as those used in electrical industries on Bus Bar
applications, Transformers, Thyroids, Transmissions, Heat Exchangers, Rectifiers, etc.
They are widely used to compensate for developed looseness due to thermal expansion of
bolted sections. |
Special Disc Springs are made of high quality Premium Spring Steel,
Chrome Vanadium (En47), and also available with Zinc Plating, Cadmium Plating. |
For corrosive environment, Disc Springs made
from Martensitic Stainless Steel duly treated are strongly recommended. |
For special applications, Disc Springs for non
magnetic stainless steel are also manufactured against request. |
