710925401 Liebherr Parts Seal Group Duo-Crane Floating Oil Seals fits R932

Description: Specifically engineered for heavy duty, rotating appliC-A-Tions, floating seals are designed to withstand extreme wear and tear. They

consist of two identical metal seal rings mounted face-to-face in separate housings, and each metal ring is centered within its housing with an

elastomeric element. This allows one half of the mechanical face seal to remain static in the housing, while the other half rotates and seals on the

lapped surfaces.

Designed for use in transmissions, pumps, axles, wet braking systems, axles, rollers, and final drives; these seals are developed using

special cast iron materials resulting in extraordinary wear-resistance. Mechanical Face seals have proven beneficial in gearboxes,

mixers, stirrers, wind-driven power stations as well as other appliC-A-Tions requiring maintenance-free lifetime sealing.

The Material of The Floating Oil Seal

Floating seal ring

Since the basic structure of cast iron is mostly sorbite pearlite or finer flake pearlite, the structure is relatively loose, which can absorb trace liquids

to form oily friction surfaces, improve lubriC-A-Tion, and adjust its chemical composition (especially the metallographic structure). ) To meet different

performance requirements, so the mechanical properties and wear resistance of cast iron are good, and cast iron has the advantages of low

price, easy processing and large thermal conductivity, so the floating seal ring mostly uses alloy cast iron.

Rubber Ring

The material used for the rubber ring requires good elasticity, low friction coefficient, resistance to medium corrosion, dissolution and swelling,

aging resistance, small permanent deformation after compression and long-term work, and non-stickiness when used under high temperature. , It

is not hard and brittle and loses elasticity at low temperature, and has certain strength and compression resistance. Therefore, under normal

circumstances, the rubber ring is mostly nitrile rubber, but also fluorine rubber, silicone rubber, hydrogenated nitrile rubber, etc.
