As the inventor of the original Bearing Isolator, Inpro/Seal continues to be a leading provider of permanent bearing protection for a variety of applications. No matter the size or complexity of the application, Inpro/Seal’s technical experts can design a custom solution for your equipment.
Bearing failures lead to expensive downtime and lost production. With Inpro/Seal Bearing Isolators you can reduce maintenance costs and double the lifetime of your rotating equipment.
The Inpro/Seal Bearing Isolator is a two part dynamic seal consisting of a stator and a rotor attached to the shaft. The rotor and stator form a non-contacting compound labyrinth seal with no wearing parts – ensuring permanent protection.
Permanently protect against high levels of contamination ingress with the Inpro/Seal VBXX Bearing Isolator.
The VBXX Bearing Isolator’s unique XX Interface blocks contaminants from entering the bearing housing. Ensuring an effective seal against water, dust, dirt and other contaminants. This design can incorporate multiple features for lubrication retention depending on lubrication type and application. The VBX® Ring inhibits the transfer of vapor contamination created by the heating/cooling of the bearing enclosure.
The VBXX Bearing Isolator can be custom engineered to meet the requirements of your application and operating environment.
The VB45-U Bearing Isolator is one of the most robust Bearing Isolator designs ever developed. It provides permanent bearing protection by protecting against lubrication loss for both oil and grease lubricated equipment and is IP66 rated for high contamination ingress protection. This unique design also handles extreme amounts of axial movement while only having a 17.78mm (0.700 in.) overall length, allowing for premium protection in limited space.
The VB45-U ensures premium protection by utilizing multiple innovative design features. The patented XX Interface blocks contaminants from entering the bearing housing while the D-Groove and Coalescing Ring protect against oil or grease loss. The unique VB45 Chamber houses the VBX® Ring to inhibit the transfer of vapor contamination created by the heating/cooling of the bearing enclosure. The unitized construction accommodates 6.35 mm (0.250 in.) of axial movement.
The VB45-S Bearing Isolator is the new standard in Bearing Isolator technology for oil-lubricated applications. The next step in permanent bearing protection, Inpro/Seal’s latest design provides the best protection against contamination ingress (IP66 rated) and lubrication loss available, at only a 15.88 mm (0.625 in.) overall length.
The VB45-S ensures premium protection in such a small design envelope by utilizing multiple innovative design features. The patented XX Interface and oversized contamination chamber blocks contaminants from entering the bearing housing while the enlarged D-Groove protects against oil loss by capturing oil on the shaft and returning to the bearing housing. The unique VB45 Chamber houses the VBX® Ring to inhibit the transfer of vapor contamination created by the heating/cooling of the bearing enclosure.
Gearboxes with flooded shafts are some of the most difficult applications to seal. Due to the flooded conditions, oil will leak through a non-contacting seal into the atmosphere. However, contact seals lose effectiveness in a short period of time due to wear, and purged seals can be expensive to purchase and maintain.
The Inpro/Seal STS Bearing Isolator effectively seals gearboxes with flooded shafts through innovative design and technology. A two-part dynamic seal consisting of a rotor and stator, the STS Bearing Isolator combines a contact seal with the patented XX Interface to eliminate contamination ingress and lubrication loss. To increase seal life expectancy, the contact seal rides on a ground stainless steel rotor that replicates the shaft surface, decreasing wear.
The STS Bearing Isolator can be custom engineered to meet requirements of your gearbox and operating environment.
mini66™ Bearing Isolator
The Inpro/Seal® mini66 Bearing Isolator, the latest innovation in Bearing Isolator technology, is the smallest IP66 rated Bearing Isolator available. With only a 0.375″ (9,52mm) overall length, the mini66 protects against both water and dust ingress on applications with very limited space. This unique design exceeds IEEE-841 standards and allows for permanent bearing protection on a wider range of rotating equipment than ever before.
As a non-contacting seal with no wearing parts, the mini66 will provide IP66 performance for the lifetime of your application. All designs are custom engineered and can be manufactured in bronze and stainless steel – making it a perfect fit for washdown and severe-duty environments.
