Frequently Asked Questions

What is a DDS rotary shaft seal used for?

A DDS rotary shaft seal prevents fluid leakage and contaminant ingress in rotating equipment such as pumps, gearboxes, and motors. Its single-lip design with spring and rubber-enclosed case suits rough bores, making it ideal for industrial machinery requiring reliable sealing in inch-dimension applications.

What are the specifications of the DDS rotary shaft seal MPN 6.3519.056.35SF?

This DDS rotary shaft seal has a 0.25-inch inner diameter, 0.75-inch outer diameter, and 0.25-inch width. It features a single lip with spring, SF design, and nitrile material. The rubber-enclosed case is designed for rough bores, and the system of measurement is inch.

How to install a DDS single-lip oil seal with rubber-enclosed case?

Ensure the bore is clean and free of burrs. Lubricate the seal lip and shaft with compatible oil. Press the seal evenly into the bore using a suitable driver, avoiding damage to the rubber case. For rough bores, the rubber-enclosed case compensates for surface irregularities. Follow manufacturer guidelines for shaft speed and alignment.
