Rotary Seals & Bearing Isolators from Parker

Bearing Isolators
Parker´s bearing isolator selection includes non-contact, labyrinth designs which provide unsurpassed bearing protection for rotary shaft equipment. It is designed to retain lubrication and exclude aggressive contaminants in non-flooded applications. Specialty isolators include dual-contacting versions for flooded and oil mist applications, among many others.
 

Rotary Shaft Seals
Rotary shaft seals provide sealing and wiping functionality for rotating and swiveling movements under low pressure and high velocity. They perform two essential functions. The primary function is to retain the bearing or system lubricant in the system to avoid leakage. The secondary function of a rotary shaft seal is to preclude any contamination of the system by external particles or other environmental impacts. Radial shaft seals typically consist of a metal insert and an elastomer diaphragm with a spring-energized sealing lip.

Rotor Seals
Rotor seals provide sealing functionality for rotating and swiveling movements under high pressure and low velocity. There are two different types of rotary seals: for the stator with dynamic sealing on the inside, and for the rotor with dynamic sealing on the outside diameter of the seal. Except for end seals in rotary distributors, rotor seals are designed for double-acting functionality.
