Bearing Isolator Labyrinth Seal


 

The Quba Seals Bearing Isolator is a non-contacting, permanent bearing protection device which consists of a unitized stator and rotor that form a compound labyrinth seal with no wearing parts – ensuring permanent protection. The stator is typically pressed into the bearing housing, while the rotor turns with the shaft. The Quba Seals Bearing Isolator protects in multiple ways. Lubricant is captured in the inner portion of the labyrinth and flows back to the bearing housing. Outside contamination attempting to enter the bearing housing is captured in the outer labyrinth paths and expelled through a port in the stator by centrifugal force and gravity.

 

The Quba Seals Bearing Isolator is a unique barrier for contamination ingress and lubrication retention for bearings
installed in pumps, motors, gearboxes, pillow blocks, steam turbines, sleeve-bearing motors, paper machine rolls, machine tool spindles and many other types of rotating equipments. This technology has been applied across a variety of industries including chemical processing, food and beverage, mining, oil and gas, power generation, primary metals, chemical processing and pulp & paper industry. No matter the size or complexity of your application, Quba Seals can design an isolator to fit your exact specifications. You can count on Quba Seals in bearing and system protection to maximize the uptime of your rotating equipment.



BENIFIT
  • Non-wearing, non-contacting, permanent bearing protection
  • Can be installed by OEMs or retrofitted on site
  • Maintenance free
  • Zero energy consumption
  • Can accommodate shaft sizes of 19.05 – 120 mm. (0.75 – 4.724 in)
  • Standard temperature tolerances range from -37ºC (-35ºF) – 204ºC (400ºF)*
  • Manufactured in bronze, stainless steel, aluminum or other materials for more extreme conditions.

INCREASE THE RELIABILITY OF YOUR ROTATING EQUIPMENT
  • Contact seals have a finite life expectancy, eventually wearing at the point of contact or grooving the shaft. Examples of contact seals are lip seals, mechanical seals and magnetic seals.
  • This short and unpredictable service life makes contact seals inadequate.
