HS split seal types
Where downtime is critical and shaft removal
is impractical, type HS all-rubber split seals are
ideal. They are simply placed around the shaft
and pushed into the seal bore, then held firmly
by a cover plate, which compresses the split
joint together. HS split seals perform best with
grease or heavy lubricants as well as with light
lubricants, placed no higher than the shaft
centreline. Horizontal shafts are preferred with
the split placed in the 12 o’clock position. HS
split seals are available in a wide variety of
types, styles and materials.
HS6
HS6 is an all-rubber split seal with a single
spring-loaded element and a Spring-Lock
(page 199). HS6 features a separate loose
spring and a positive spring connection.
Generally, the spring connection is of the
hook-and-eye type for shafts over 457 mm
(18 in) and a threaded-type connection for
smaller sizes. For proper fit, a cover plate is
required.
HS7
HS7 is an all-rubber split seal with a single
spring-loaded element, which has both a
Spring-Lock and a Spring-Kover (page 199). A
control-wire spring connector is used to join
the seal together (fig 72). HS7 does not have
the high performance as other HS types, but it
is the easiest one to install. The spring is
completely enclosed and the connection is
simply made by running the control wire into
the center of the spring coil across the split
(butt joint). Spring tension to hold the sealing
lip on the shaft is built-in at the factory. For
proper fit, a cover plate is required. Due to the
unique design that permits easier installation,
please note that a gap may occur at the joint
even after the cover plate is installed. Special
attention to place the gap at the 12 o’clock
position during installation is necessary.
