V-Rings VR-VS

Description

Seal for rotary sealing made entirely of elastomer. The joint consists of a body and a front closing lip. The elasticity of the body together with the interference between it and the shaft, keeps the joint attached and rotating solidly with the shaft, without the need for a specific housing. The lip is exactly the same as the VA, but the body is more robust and a smaller range of measurements.

Assembly

The V-Ring VS is mounted by expanding it slightly to slide it over the shaft, ensuring that the lip is in uniform contact with the bearing surface, avoiding sharp edges and singing edges if necessary, and checking that the seat is clean and perpendicular to the shaft to ensure a correct seal.

Advantages

Standard design with reinforced body.
Excellent dynamic sealing effect thanks to the front lip.
Suitable as a primary sealing element or in combination with radial seals.
Capable of compensating for small axial displacements as well as angular and radial misalignments.
Direct installation on the shaft without the need for specific housing.
Friction decreases as peripheral velocity increases.
High body elasticity, ensuring a secure hold due to interference with the shaft.
Effective protection against dust, dirt, oil splashes, grease or water.

Materials

Available in NBR, FKM, CR, HNBR and VMQ materials, with hardnesses between 60 and 80 Shore. These compounds offer an optimal combination of flexibility, chemical resistance and thermal stability, enabling reliable performance against dust, splashes, oils, greases and atmospheric agents. Its elastic structure guarantees adequate adaptation to the shaft and an effective seal even in the event of misalignments or vibrations.
