Description
Structural Design:
At its core, the TB type is equipped with a spring-loaded sealing lip, which delivers excellent dynamic sealing performance against lubricants.
What makes this seal unique is the additional protective dust lip, designed to keep out external contaminants such as dust, dirt, and moisture.
This dual-action sealing concept makes the TB oil seal an ideal choice for machinery operating in harsh conditions, offering both internal sealing reliability and effective external protection.
Summary of Advantages:
- Good radial rigidity, particularly for large diameters
- Good stability when assembled, preventing the bounce-back effect
- Sealing for low and high viscosity fluids
- Modern sealing lips with low radial forces
- Protection against undesirable air contaminants
Typically made from polyurethane, alternative materials can be provided upon request to suit your specific needs.
