Description
High-quality rotary lip seals built for industrial gearboxes—stable sealing, cleaner lubrication, and fewer maintenance stops.

High-Quality Radial Shaft Seals for Industrial Gearboxes

Built for stable gearbox sealing

Designed for rotating shafts in industrial gearboxes, these radial shaft seals help retain lubricant and minimize contamination—supporting smoother operation and longer service intervals.

Highlights

  • Consistent radial load with spring-energized lip

  • Optional auxiliary dust lip for harsh shop-floor environments

  • Material options for oil compatibility and temperature demands

  • Replacement-friendly DIN 3760 / ISO 6194-style geometry

Selection tip

For higher temperatures or aggressive media, consider FKM or PTFE compounds; for general-purpose oil sealing, NBR is a common choice.
