VA (V RING)

product

VA is a V-Ring designed to be used for rotating shaft applications.

PRODUCT ADVANTAGES

  • Easy fitting and requires little space
  • Functions even with poor surfaces
  • The one size of V-seal can be used for shafts of several different diameters
  • Low friction
  • Economical sealing solution

APPLICATION
Electric motors-limit switches , agricultural machinery , automotive engineering and special applications of rotating systems

INSTALLATION
Assembly of the v-ring is easy and does not require much time. The ring is expanded and pulled over the shaft. It is then brought into position with a rounded screw-driver or similar tool. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.

NOTES
For special applications that require high temperatures , V-rings VA can be produced in FPM material.

MATERIAL: NBR 70 SH
