Seals type BO

DIN 3761 Type BO seals are characterized by having a primary sealing lip without a reinforcing spring, making them ideal for applications with less demanding operating conditions or where constant pressure on the shaft is not required. This simplified design results in reduced friction and facilitates operation in low-speed or low-pressure environments.

Like the Type BS, the Type BO features an exposed metal case, which provides a robust structure and dimensional stability during installation. However, its springless design limits its use to applications where lubricant loss is minimal and the operating environment is controlled, such as in static equipment or low-demand mechanical systems.

This type of seal is particularly suited for sealed systems with stable lubrication, where there are no sudden pressure changes or significant presence of external particles. Its construction allows for easy installation and cost optimization, making it an effective solution for auxiliary equipment, electric motors, low-pressure pumps, and similar applications.

Type BO is available in various diameters and materials to suit the requirements of each application.
