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.
- 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.
- 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.
