[AT] Shaft seal

[H. L. Staples]

The V-ring seals have been discussed on this before.  They can be installed
on the shaft and run against the existing seal flange outer surface. The
nice thing about them is that they can be installed, space permitting,
without removing the old seal. The following was copied from an Internet
site.  
 
"V-Ring Seals are used with grease or oil lubrication. V-rings include a
rubber body and a sealing lip that exerts a light axial pressure on the
sealing surface. This type of seal is simple to fit and at slow speeds
permits relatively large angular misalignments of the shaft with respect to
thin the original seal size, which are used. These sleeves are commercially
available in many popular bearing sizes. V-rings are generally fitted on the
outside of the housing with grease lubrication and on the inside of the
housing with oil lubrication. V-ring seals are unique all-rubber seals for
rotary shafts. V-rings are mounted on and rotate with the shaft. These rings
are normally made of nitrile rubber. V-rings are made entirely of elastomer
without fabric or sheet metal reinforcement."
