V-
Ring seal is used with SNA,
SNH, and SNL housings. For
SDG and PDN type housings,
V- Ring seal are used as supplementary
seal to enhance sealing efficiency.
V-Ring
seal consist of a V-ring
and steel sheet washer (TA).
It is designated as TA or
TSNA
500A or TSNA 600A
The V-ring
of synthetic rubber has a
thin sealing lip which acts
in an axial direction. The
ring also servers as a flinger
as it rotates with the shaft.
This type of seal is effective
under most operating conditions.
V- ring is normally suitable
for peripheral speeds up
to 12 meter/sec although
axial location for the v-ring
must be provided at peripheral
speeds in excess of 7meter/sec.
Higher speeds than 12meter/sec
can be permitted if the V-Ring
body is also radially clamped,
using a steel ring. The maximum
permissible misalignment
of the shaft is approximately
1.5. degree for a shaft diameter
of 50 mm, which decrease
to approximately 1 degree.
for a shaft diameter of 150
mm.
V-ring
seals are suitable for temperature
range of -40.0 C to 1000
C , grease lubrication and
vertical mounting but less
suitable in axial shaft displacement
oil lubrication. For external
condition with dust, sand
and splashing fluid, V-ring
seals are selected, but they
are not suitable with grit,
sharp objects, chipping,
splinters and sunshine.
