Frequently Asked Questions

What is a DDS rotary shaft seal used for?

A DDS rotary shaft seal prevents lubricant leakage and blocks contaminants in rotating equipment such as pumps, gearboxes, and motors. Its single-lip design with spring and rubber-enclosed case suits rough bores, making it reliable for industrial machinery across machining, power transmission, and material handling applications.

What are the specifications of the DDS 24.5408.5SF rotary shaft seal?

The DDS 24.5408.5SF is a metric SF-design single-lip oil seal with a nitrile lip and spring. It has a 24.5 mm inside diameter, 40 mm outside diameter, and 8.5 mm width. The rubber-enclosed case is engineered for rough bores, providing secure sealing in demanding industrial environments.
