PRODUCT DESCRIPTION
The V-ring serves as a lip seal but also as a centrifugal ring. The V-ring sits expanded on the shaft and must be mounted at right angles at a precisely defined distance from the metallic counter-running surface to ensure axial preload of the sealing lip. The end face of a bearing, the end wall of a housing, a shaft collar and a flange cover serve as a counter-running surface. The V-ring rotates with the shaft and seals axially on the counter-running surface. As the circumferential speed increases, the sealing lip strives outward due to centrifugal force, thereby reducing the contact pressure. From a certain circumferential speed, the sealing lip lifts completely off the metallic counter-running surface. The V-ring then only acts as a gap seal and centrifugal disc.
PRODUCT BENEFITS
- simple sealing element - seal against dirt, grease, oil or water splashes - can be used well in combination with radial shaft seals - low requirements on the counter-running surface in terms of surface quality - simple installation - is stretched on the shaft - the running friction decreases with increasing circumferential speed due to the centrifugal effect - good dynamic sealing effect - compensates for small axial movements as well as angular and radial offset - protects radial shaft seals from abrasive environmental conditions
PRODUCT DESCRIPTION
The V-Ring serves as a lip seal but also as a centrifugal disc. The V-Ring is stretched onto the shaft and must be installed at an accurately defined distance from the counter-rotating metal surface to guarantee axial preload of the seal lip. The end of a bearing, the bearing case or a shaft collar serve as counter-rotating surface. The V-Ring rotates with the shaft and seals axially on the counter surface. With increasing peripheral speed, the seal lip is pulled outwards by the centrifugal force and the contact pressure is reduced. At a certain peripheral speed, the seal lip lifts off the counter metal surface completely. The V-Ring then functions only as a gap seal and centrifugal disc.
PRODUCT ADVANTAGES
- single function sealing element - seals against dust, dirt, lubricant, oil or water spray - works well in combination with rotary shaft seals - low demands on the counter surface with regard to the surface quality - simple installation - is stretched onto the shaft - the dynamic friction reduces with increasing peripheral speed due to the centrifugal force - good dynamic sealing effect - balances and well-setting conditions from axial segments
