Overview
The Garlock 29502-4108 is a KLOZURE® ISO-GARD® bearing isolator labyrinth seal engineered for industrial pump, motor, and gearbox applications. This flanged isolator uses a patented unitized labyrinth design to exclude contamination while retaining bearing lubrication, ensuring extended equipment uptime and reduced maintenance costs. Manufactured in the USA with glass-filled PTFE, it delivers non-contact, non-wearing sealing performance across demanding operating environments.
Key Features
- Labyrinth Seal Design: Non-contact engineered geometry prevents contaminant ingress and lubrication egress without wearing components or shaft drag
- Glass-Filled PTFE Material: Durable, corrosion-resistant construction rated for harsh industrial conditions and flooded lubrication applications
- Cam-Lock O-Ring Grooves: Patented retention system enables fast hand-installation without arbor press; snap-fit assembly reduces downtime
- Flanged Configuration: Standard flange design with 0.375 inch mounting lip for secure housing fit and axial positioning
- Made in USA: Precision-engineered by Garlock, backed by decades of rotating equipment sealing expertise
