End Cap Covers Seal Plug Seal Ec 16*6 for Gearbox

Product Description

End Cap Covers  Oil Seals(EC/VK/CAP):
End caps are designed for applications where the shaft does not pass through the housing wall of the bore.  The end cover provides protection for the bearings.  The covers are designed to fit into housing bores for rotary shaft seals.  They have the same tolerances as those for the O.D. of a seal. The inner housing is carbon steel and the outer seal is nitrile rubber.  It is mainly used for the orifice, the core opening and the bearing of an oil seal, which is particularly used as a substitute for an end flange or an end cover in a gear box, and the rubber layer at the outer diameter ensures the oil leakage in the oil seal seat. At the same time, it also strengthens the neatness and beauty of the cabinet.
