HDS7
Metal clad seal series
General
The most popular seal group in the SKF LDS
line is the metal clad seal series with the HD
seal designs.
The HD designs include the highly engineered
HDS7, the ultra-high performance HDL and
the reliable HDS1, HDS2 and HDS3 seal. SKF
HD seals are specifically designed to withstand
the extreme conditions encountered in heavyduty
applications.
The seals perform exceptionally well in the
highly contaminated environment of metal
rolling mills, the high speed and high
temperature environment of paper mills, as
well as more universal applications such as
industrial gearboxes. The metal clad seal series
has a product to perform in almost any
industrial application.
Type HDS7
Water and solid contamination particles are
common causes for bearing failures. SKF has
developed the HDS7 as a grease seal with
enhanced exclusion capabilities.
The highly engineered HDS7 features a
computer optimized, springless lip profile
designed to retain lubricants and aggressively
pump contamination away from the lip. The increased
ability of the HDS7 to exclude
contamination makes it an ideal equipment
protector in heavily contaminated
environments such as the water and scale
present in rolling mill applications. The
springless lip concept of the HDS7 also reduces
radial load.
The HDS7 is available in a nitrile lip material
for common applications, Duratemp ® for
higher temperature conditions and Duralip ®
for applications where extra abrasion
resistance is necessary.
It is important to note that the HDS7 is not
available in FPM (LongLife ® ) material.
The HDS7 is available in all shaft sizes
ranging from 200 to 1 575 mm (8 to 62 in).
Spacer lugs are available for any configuration,
see page 198 for further information.
