The V-Ring is known for its durable, yet tight-fitting grip strength. It produces tight contacts and restorations, while producing a uniform shape. The V-Ring serves as the lip’s seal and also as the centrifugal disc. It is used mainly in combination with other types of seals (such as rotary shaft seals) and as pre-sealing elements for bearings and shafts.
The V-Ring Has Many Advantages, Including:
- Superior Grip Strength
- Excellent Durability
- Protection of Rotary Shaft Seals from Abrasive Environmental Conditions
- Single-Element Sealing against Dust, Dirt, Lubricant, or Water
- Exceptional Performance when Combined with Rotary Shaft Seals
- Dynamic Friction Reduces with Increasing Peripheral Speed due to Centrifugal Force
Allied Metrics Offers V-Rings in a Variety of Materials, Including:
Buna, which is also known by other names such as NBR, Buna-N and Nitrile Rubber, is an excellent material that is able to perform well within temperature ranges between -40° degrees Celsius to 100° degrees Celsius.
Silicone, a heat-resistant, rubber-like material. Silicone has low thermal conductivity, low chemical reactivity. It is resistant to oxygen, ozone and ultraviolet light. It also has a high gas-permeability.
Urethane, a form of plastic that is formed when urethane resin and urethane hardener are combined. It offers good resistance against mineral oil, acid and bases.
EPDM, a synthetic rubber and is also known as M-class rubber. EPDM offers good compatibility with fireproof hydraulic fluids, ketones, alkalis and water. It is not compatible with most oils, gas, kerosene halogenated solvents, acids and aromatic and aliphatic hydrocarbons.
