HDL seals
The HDL is a premium metal clad oil seal that
is especially designed to operate in severe
conditions including high speeds and
temperatures, high runout and high
misalignment. The excellent high-speed
performance characteristics of the HDL make
it the preferred design in the severe
environment encountered in the rolls of the
papermaking machines.
The HDL features a stainless steel garter
spring that is entrapped by individual finger
springs, also made of stainless steel, around
the entire circumference of the seal.
The spring combination allows the seal to
compensate for severe conditions in order to
maintain high levels of sealing performance,
operational life and equipment reliability.
The HDL series also comprises type HDLA
with a secondary (dust) lip for extra protection
against contaminations.
The HDL is available in lip material nitrile
rubber, Duratemp and LongLife (pages 28 and
29), ensuring that the HDL will perform
regardless of speed or temperature. Spacer
lugs are available for all products within the
HDL line. Available HDL sizes can be found in
the size listing (page 214 to 243).
HDS1, HDS2 and HDS3
The most commonly used metal clad seal is
the HDS series for general purpose applications.
HDS seals are divided into the
HDS1, HDS2 and HDS3 categories.
All three seal versions are encased in a
heavy-duty steel shell and a SAE 302 series
stainless steel spring is standard.
The basic HDS1 has its stainless steel spring
mounted in a protective Spring-Lock groove.
Where blind installations may increase the risk
of spring displacement, the type HDS2 adds a
Spring-Kover that bonds the spring into the
groove. The HDS3 adds a spark-free inner
diameter, standard Duralip material and
