Update:2018-12-08

The V-shaped seal is used to prevent external dust, powder and water. DSH seal shared with you about the structural design and application of the V-shaped seal.

The V-shaped seal is a seal made of pure rubber (shown in Figure 1 is a V-shaped seal cross-section structure), which can be directly mounted on the shaft, and cooperates with the contact surface, the cavity, the seal shell and the like. 

Can be used as a primary or secondary seal. Because it is a pure rubber seal, his elasticity is better than the same V-shaped seal, and it can also be stretched and assembled. The product types we offer: DVS/DVA is the most common style and the most widely used; 

DVS/DVA is the original design structure, designed into a wide body and a cone root, which makes it better to hold the shaft, usually For automotive and agricultural applications; DVS/DVA is a narrow-section seal with a compact structure for replacing labyrinth seals on the pedestal; 

DVS/DVA is a heavy-duty large-diameter seal that allows for large axial displacements, where DVS/DVA  has the largest cross section and is usually used for dustproof and waterproof seals on rolling mills; it is generally used on shaft steel machines, ball mills and paper machines.
