An oil seal, also known as a radial oil seal, radial shaft seal, or rotary shaft lip seal, is a circular sealing device used to seal between two machine parts that rotate relative to each other. They are used to seal lubricants and/or block contaminants, or to separate different media.
They are available in metric and imperial sizes, and are suitable for single-lip and double-lip designs. NSAR offers a variety of seals for rotary and shaft solutions. These include oil seals, grease seals, shaft seals, and mechanical seals. Seals are available in a variety of different configurations, including but not limited to: single or double lip, with or without springs, and double spring lip formats.
