V-ring seal VS

rotaryelastomerNBR

Description
The V-ring VS is an axial sealing, single-acting seal designed for non-pressurized shaft and bearing sealing applications. It seals against the vertically arranged front surface and is mounted expanded on the inner diameter to ensure a tight fit on the shaft.

Fields of application

• static
• dynamic
• single-acting
• double-acting
• linear
• rotating
• oscillating

Main use
Contaminant-exclusion seal for shaft outlets with improved shaft fit

Materials
Elastomers (standard: NBR with ozone resistance, FKM). Other materials available on request.

Technical values (typical / material dependent)

• Material variants: NBR, FKM
• NBR — Pressure: not for pressurized applications; Temperature: -30°C to +100°C (material dependent); Speed: up to 8 m/s; up to 12 m/s with axial fixation
• FKM — Pressure: not for pressurized applications; Temperature: -20°C to +200°C (material dependent); Speed: up to 8 m/s; up to 12 m/s with axial fixation
• Maximum values for temperature, speed and pressure are not simultaneously applicable and vary depending on material and media
