Frequently Asked Questions

What is the DDS Rotary Shaft Seal used for?

The DDS Rotary Shaft Seal is a single-lip oil seal designed to retain lubricants and exclude contaminants in rotating shaft applications. It is ideal for rough bore housings where a rubber-enclosed case provides improved sealing in less-than-perfect bore surfaces, common in industrial gearboxes, pumps, and heavy machinery.

What are the specifications of the DDS Rotary Shaft Seal 190.5228.614.28SC?

How to install a DDS Rotary Shaft Seal with a rubber-enclosed case?

Ensure the bore is clean and free of burrs. Lubricate the seal lip and outer diameter with compatible oil.

Avoid damaging the nitrile lip or spring during installation for optimal performance.
