cassette oil seal

XING TAI S&P MECHANICAL SEAL FACTORY

Cassette oil seal/Labyrinth oil seal

The cassette seals are generally made up of a sleeve, sealing lip with a spring and several anti-dust lips integrated into a labyrinth system to protect against external pollution, and are distinguished by greater system reliability and longevity. Furthermore, their friction surface, which has been adjusted and finished beforehand, does not require any shaft maintenance during replacement.

a.Metal/rubber outside diameter
The cassette seal's outside diameter design provides better static sealing against low-or high-viscosity fluids, limited bounce-back effect, accurate positioning and a solid foundation for the seal in its housing, as well as better heat dispersion.
b.Pre-lubricated areas
Depending on the application, a compatible lubricant is applied to different areas inside the cassette seal, whichenables better heat dispersion, lubricates addtional sealing lips during friction and prevents the entry of external pollutants.
c.Rubber bumpers
Rubber bumpers correctly position the sleeve with the primary sealing lip. They also ensure an appropriate level of restriction or interference using various additional barriers, and reduce the entry of external pollutants into the system.
d.Primary sealing lip
The primary sealing lip is pre-stressed by a spring, which guarantees optimal sealing against media when in rotation, whilst compensating for potential shaft run-out and eccentricity faulis. The sealing lip's optimised geometries ensure reduced friction and longer product lifespan.
e.Metal/rubber inside diameter
The cassette seal's inside diameter interior is designed to offer better static sealing against low-or high-viscosity fluids, and reduce installation effort during assembly.
f.Curved metal part
The curved metal cage on the outside of the cassette seal allows for easy assembly and disassembly, and prevents the seal from coming apart during transport or maintenance operations.
g.Conactless barrier
The rubber baffle is a contactless barrier that limits the entry of external pollutants.
h.Additional anti-pollution sealing lips
Additional sealing lips can be radial or axial, depending on the cassette seal profiles and additional barriers against external pollutants.
i.Ground metal cage
The metal part of the cage that is in contact with the sealing lip(s) is ground in order to improve surface toughness, reduce friction and increase the seal's lifespan.
