Frequently Asked Questions

What is a DDS rotary shaft seal used for?

A DDS rotary shaft seal prevents lubricant leakage and contaminant ingress in rotating equipment such as pumps, gearboxes, and motors. Its single-lip nitrile design with spring maintains sealing pressure on shafts, making it suitable for industrial applications requiring reliable oil retention.

What are the specifications of the DDS 8210512SF rotary shaft seal?

The DDS 8210512SF is a metric SF-design single-lip oil seal with a rubber-enclosed case for rough bores. It has an 82 mm ID, 105 mm OD, and 12 mm width. The lip is nitrile with a spring, providing effective sealing in moderate-temperature industrial environments.

Where to buy DDS rotary shaft seals worldwide?

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

Ensure the housing 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 driver that contacts the outer case only, avoiding damage to the rubber enclosure. Never hammer directly on the seal.
