Overview
The Inpro Seal 1987-A-02356-0 is a precision bearing isolator engineered to provide permanent protection for rotating equipment. This innovative non-contacting design consists of a unitized stator and rotor that form a compound labyrinth seal with no wearing parts, ensuring permanent bearing protection against lubrication loss and contamination ingress. This unit is supplied new in box and ready for immediate deployment in industrial bearing applications.
Key Features
- Non-Contacting Seal Design: A two-part dynamic seal consisting of a stator and rotor working in conjunction to form a non-contacting compound labyrinth seal with no wearing parts
- Contamination Protection: Protects against lubrication loss and contaminants such as dirt and moisture entering the bearing housing
- Zero Wear Components: Bearing isolator keeps lubricants in and contaminants out through a labyrinth seal design with no wearing components
- Permanent Protection: Inpro/Seal as the inventor of the Bearing Isolator has delivered proven permanent bearing protection for rotating equipment for over 45 years
- Dual Function VBX Ring: When at rest, the Inpro/Seal VBX ring effectively seals the labyrinth; during operation, centrifugal force lifts the VBX ring away from contact with the stator to create a non-wearing permanent seal
