1. Product Introduction
TCV type pressure-resistant skeleton oil seal is specially designed for medium and low pressure, rotating and oil-lubricated working conditions. It features a short and thick sealing lip, minimal deformation under pressure, excellent pressure resistance, and is ideal for small-diameter shaft applications. Widely used in hydraulic pumps, motors, reducers and other rotary equipment sealing scenarios, with stable performance and long service life.
2. Structure Feature
-
Composition: Carbon steel metal skeleton + rubber elastomer (NBR/FKM) + tension spring (partial models).
-
Double lip design: Main sealing lip for effective oil sealing, auxiliary dust lip for preventing dust and impurities from entering, protecting the sealing surface.
-
Short & thick lip structure: High rigidity, stable pressure resistance, not easy to deform under medium pressure, better performance than ordinary TC type oil seal.
-
Inner encapsulated skeleton design: Interference fit to install into the cavity, tightly hold the shaft surface, easy to install and stable in sealing.
