Watch the Bearing Isolator video
lnpro/Seal's Bearing Isolator is a two-part dynamic seal consisting of a stator and a rotor ... working in concert to form a non-contacting compound labyrinth seal – with no wearing parts.
When at rest, the patented lnpro/Seal VBX ring effectively seals the labyrinth – blocking condensation and other contaminants from entering the bearing housing. During operation, centrifugal force lifts the VBX ring away from contact with the stator to create a non-wearing permanent seal. Outside contamination attempting to enter the bearing housing is captured in the outer labyrinth paths and expelled through a port in the stator.
Bearing lubricant is captured in the inner portion of the labyrinth and directed back into the bearing housing.
Custom engineered designs can be split for easy installation and come with an unconditional performance guarantee.
Inpro/Seal Bearing Isolators ensure permanent bearing protection – increasing the reliability of your rotating equipment.
