Radial shaft seals (oil seals)
Radial shaft seals (also named as oil seals or simerings) are sealing devices whose function is to close the gap between rotating shafts and fixed parts to prevent the leakage of liquids, oils or other substances. These seals are widely used in various industrial equipment, machinery and vehicles, ensuring reliable and long-term operation. Radial shaft seals are made in different sizes and materials to meet specific industrial requirements.
