Engineered Sealing Solutions
Bearing isolators provide reliable, non-contact protection for rotating shafts by combining a rotor and stator to seal out contaminants like dust, moisture, and chemicals while retaining lubrication. Unlike traditional lip seals, they operate without friction or wear, extending bearing life and reducing maintenance downtime. Ideal for pumps, motors, gearboxes, and other rotating equipment in harsh industrial environments.

Common questions about Bearing Isolators
A lip seal makes physical contact with the shaft and wears over time, while a bearing isolator uses a rotor-stator design with no contact, eliminating wear and friction.
Yes, most are designed as drop-in replacements for standard lip seals without modifying the housing.
Commonly bronze, aluminum, or stainless steel, depending on the operating environment and load requirements.
No - they're designed to run maintenance-free for the life of the bearing.
