Bearing Isolators
Advanced Bearing Isolators for Maximum Equipment Protection
At GSI – Globe Seal Industries, we engineer and supply high-performance bearing isolators that safeguard critical rotating equipment by preventing lubricant leakage and blocking external contaminants. Our bearing isolators help you achieve longer bearing life, reduced maintenance costs, and improved reliability for demanding industrial environments.
Product Overview
Bearing isolators are non-contact, dynamic sealing devices designed to protect bearings by creating an effective barrier against contaminants while retaining lubricants. Unlike traditional contact seals, bearing isolators operate without friction, ensuring long-term performance without wearing out shaft surfaces.
At GSI, we offer both standard and custom-engineered bearing isolators, precisely designed to fit your equipment and operating conditions.
Key Features
✔ Non-Contact Design: Labyrinth-style construction eliminates friction, heat generation, and shaft wear, enabling virtually indefinite service life.
✔ Effective Contaminant Exclusion: Keeps out dust, dirt, moisture, and other contaminants that lead to premature bearing failures.
✔ Superior Lubricant Retention: Prevents oil or grease from leaking out, maintaining proper lubrication inside housings.
✔ Custom Configurations: Available in split or solid designs for easy installation on existing equipment.
✔ Dynamic Pressure Balance: Engineered to maintain sealing efficiency during shaft rotation and transient pressure changes.
Materials of Construction
Our bearing isolators are crafted from premium-grade materials to ensure durability and compatibility with a wide range of industrial applications:
Aluminum & Bronze Alloys: For excellent strength, thermal stability, and corrosion resistance.
Stainless Steel: Ideal for aggressive environments requiring higher corrosion protection.
Engineered Polymers & Composite Inserts: For specific chemical, temperature, or non-sparking requirements.
Applications
GSI bearing isolators provide critical protection in applications such as:
Pumps & Compressors
Gearboxes & Speed Reducers
Electric Motors & Generators
Fans & Blowers
Mixers & Agitators
Paper, Steel, Cement, and Mining Machinery
