Tungsten Carbide Type U Seals

Introduction

Tungsten carbide type U seal is a kind of seal with sealing application. As the section of seal with type U, so it called U seals. Type U seal is a kind of sealing lip with a symmetrical configuration, which is used in single-acting piston or double-acting hydraulic cylinder standard.

Tungsten carbide type U seal is the most conmen seals in hydraulic cylinder, which is a typical Lip seal, it with the same affect in single-acting piston or double-acting hydraulic cylinder standard. In the low pressure situation, rely on lip seal interference deformation, due to the small contact area, friction is relatively low, as the pressure increases, the elastic deformation of the lip increases the tensile, compressive and bending stress increases, U-ring radial pressure clamping force automatically increases the length of contact with the sealing surface increased until the entire axial length of the U-ring seal in contact with the surface, so as to ensure a good seal under high pressure.

Features

Well corrosion, high temperature, wear-resistant.

Advantages

1. Has no effect for overloaded and the piston rod bending, compared with the lip, seald with less friction under the low pressure range.

2. Good corrosion and wear resistance, good lubricating oil film formed in the sealing gap, no effect on sudden load.
