The 442 Series High Speed Rotary Seal is a premium seal that offers a significant advantage over traditional rubber-and-textile rotary seals through its highly flexible, dual-construction internal metal spring and seal lip. The high flexibility of the seal lip and spring combination allows for use in applications with large deflections or very high speeds. The seal body has an internal reinforcing metal ring that ensures high retention during installation.
