B6 Bearing Protector

Structure and Sealing Principle

● Mainly composed by rotating ring (part 1), static ring (part 2), and floating o-ring 　 (part 3). ● The static ring is fixed to the chamber through the stator o-ring (part 4), and a oil 　return channel directly below the oil storage tank. ● The rotating ring is fixed to the rotor through the rotor o-ring (part 5), forming 　several 90° bending and buffering chambers with the static ring. Impurities from 　the outside are discharged through the drain tank directly below by gravity and 　centrifugal force. ● The specially designed floating o-ring locks the static ring and rotating ring into 　one unit, which acts as a static seal when stationary, achieving sealing between 　the bearing and the external environment; During operation, the floating o-ring 　"lifts" under the action of centrifugal force, greatly reducing wear, and the 　expansion gas generated in the bearing cavity is safely released.

Quality Assurance

The whole set of bearing protectors shall operate continuously without faults for no less than one major overhaul period, and it is generally recommended to replace them every three years.

Special Note

Bearing protectors are different from contact seals, the basic model B6 cannot be used for pressurized working conditions. We can customize products with various materials and structural types to comply with the individual needs of customers.

Recommended Applications

● Pump　　　 ● Gearbox ● Blower　　　 ● Motor ● Other Industrial Rotating Equipment

Technical Service

Provide on-site technical services and operation training, and guide on-site installation, debugging and maintenance. The supplier should promptly respond and solve any problems that arise during operation and maintenance.
