V-Ring VA is used for dust proof and waterproof

V-ring VA can be stretched open directly installed on the shaft, fixed by the internal tension of the rubber body. It as the axis of rotation axis in the direction of vertical pressure shaft surface static sealing effect, the dynamic seal friction surface can be bearing wall, or washers, stamping parts, bearing, and even metal skin oil seal, the sealing lip is flexible, and only relatively small contact pressure to the friction surface, but enough to keep the sealing function. Dry operation of seals is allowed in many applications because of low contact pressure.
