Lipped seal 30

with circular cross sectionpolymermetal

Overview
Omniseal® 30 and 40 rotary lip seals feature a threaded sealing lip that pumps lubricating media away from the sealing interface. These designs are intended for use in lubricating media only and provide sealing performance within specified PV and pressure limits.

Materials & Design
Proprietary high-performance polymer compounds are combined with optional metal outer cases and engineered geometries. Material combinations are selected to meet application-specific requirements and manufacturing standards.

Applications

• Engine crankcase seals.
• Spindles and similar rotary shaft assemblies.
